Roof coating ASTM standards are material specifications, not system warranties. ASTM D6083 covers water based acrylic coatings, ASTM D6694 covers silicone coatings used over spray polyurethane foam, and ASTM D6947 covers moisture cured polyurethane coatings over spray foam. Each one sets minimum lab values for elongation, tensile strength, permeance, adhesion, tear, weathering and low temperature flexibility. None of them tests wind uplift, fire class, or how long the coating lasts on your roof.
This page maps each specification to the product it governs, names the underlying test method behind every property, and shows how to read a real coating data sheet against the standard it claims. It also corrects the most common error in coating literature: the belief that ASTM D7311 is the SEBS coating specification.

Which ASTM standard applies to your roof coating?
Match the specification to the binder chemistry, then check the scope. ASTM D6083 applies to water dispersed acrylic latex. ASTM D6694 applies only to solvent dispersed coatings that are more than 95 percent silicone polymer and only when used over spray polyurethane foam. ASTM D6947 applies to single component moisture cured urethane over spray foam. Asphalt based coatings sit under a separate family of specifications entirely.
| Standard | Current designation | Product type | Scope limit written into the standard |
|---|---|---|---|
| ASTM D6083 | D6083/D6083M-24 | Liquid applied acrylic (water dispersed latex) | Material properties only. Explicitly provides no application guidance. |
| ASTM D6694 | D6694/D6694M-25 | Liquid applied silicone, more than 95 percent silicone polymer | Written for use as a membrane over spray polyurethane foam insulation. No application guidance. |
| ASTM D6947 | D6947/D6947M-16(2023) | Single component moisture cured urethane | Written as a protective coating for spray polyurethane foam roofing systems. |
| ASTM D3468 | D3468/D3468M-99(2020) | Liquid applied neoprene and chlorosulfonated polyethylene (CSPE) | Roofing and waterproofing solutions. Legacy chemistry, rarely quoted on current data sheets. |
| ASTM D1227 | D1227/D1227M-13(2024) | Emulsified asphalt protective coating | Built up roofs and exposed surfaces at inclines of not less than 4 percent (1/2 in. per ft). |
| ASTM D2824 | D2824/D2824M-18(2024) | Aluminum pigmented asphalt roof coating, fibered and nonfibered, asbestos free | Material only. Application is covered separately by Guide D3805. |
| ASTM D4479 | D4479/D4479M-07(2024) | Asbestos free asphalt roof coatings, brush or spray consistency | Material only. |
All designations above were confirmed against the current ASTM catalog listings in August 2026. The acrylic and silicone specifications are both maintained by ASTM Subcommittee D08.09 under Committee D08, Roofing and Waterproofing.
What ASTM D6083 actually tests on an acrylic coating
ASTM D6083 covers water dispersed acrylic latex elastomeric roof coatings and splits its requirements into liquid properties and dry film properties. Per the published ASTM abstract, the liquid side covers viscosity plus volume and weight solids. The dry film side covers initial elongation at break, initial tensile strength, final elongation after accelerated weathering, permeance, water swelling, adhesion, fungi resistance, tear resistance and low temperature flexibility after weathering.
The values were not invented in a lab. Writing in IIBEC Interface in January 2001, William A. Kirn, RRC, then secretary of the ASTM D08 Polymeric Materials Subcommittee, described how the task group identified acrylic coatings already performing successfully on more than 20 in service roofs aged from three to 20 years, measured their lab properties, and set the minimums from that field record.
One detail almost no product page mentions: D6083 recognizes more than one type. GAF’s published data sheets label their acrylic top coats as passing Type 1 or Type II, with different low temperature flexibility thresholds attached (a 0.5 inch mandrel bend at minus 15 F for one, and at 14 F for the other). A coating that “meets ASTM D6083” without naming a type has told you less than it appears to.
What ASTM D6694 actually tests on a silicone coating
ASTM D6694 covers a liquid applied, solvent dispersed elastomeric coating whose principal polymer is more than 95 percent silicone, used as a roofing membrane over spray polyurethane foam. The published abstract lists liquid properties (viscosity, volume solids, weight solids) and cured film properties: elongation, tensile strength, permeance, accelerated weathering, adhesion, tear resistance and low temperature flexibility.
Two things follow from that scope. First, the 95 percent silicone threshold is what separates a true silicone from a silicone modified product, so the standard doubles as a purity claim. Second, the specification is written around spray foam. Manufacturers routinely and legitimately sell D6694 compliant silicone for metal, TPO, PVC, EPDM and modified bitumen: GAF’s High Solids Silicone data sheet lists all of those as approved substrates. But the compliance testing behind the number, including the adhesion test, is framed for foam. Adhesion over an aged, weathered single ply is a separate question that the standard does not answer, which is why every silicone manufacturer tells you to run adhesion test patches first.
The D7311 and SEBS mix up: there is no published SEBS coating spec
ASTM D7311 is frequently cited online as the SEBS roof coating standard. It is not. The ASTM catalog lists D7311 as “Standard Specification for Liquid-Applied, Single-Pack, Moisture-Triggered, Aliphatic Polyurethane Roofing Membrane,” and it was withdrawn in 2013. Specifying it today means specifying a document ASTM no longer maintains.
As of August 2026 there is no published ASTM specification for liquid applied SEBS (styrene ethylene butylene styrene) roof coating. What exists is an open ASTM work item, WK85130, titled “New Specification for Liquid Applied SEBS Thermoplastic Rubber Coating Used in Roofing.” A work item is a draft in the balloting pipeline, not a standard you can cite in a specification.
The one published ASTM document with SEBS in the title is D6152/D6152M-12(2024), SEBS-Modified Mopping Asphalt Used in Roofing. That is a hot applied bitumen for built up roofing, not a coating. If a SEBS coating submittal cites either D7311 or D6152 as its governing specification, the citation is wrong, and the honest answer from that manufacturer should be that the product is tested to individual ASTM test methods with no umbrella specification behind them.
The property tests behind the numbers
The specifications above do not contain their own test procedures. They point at separate ASTM test methods, which is why the same property can appear with different method numbers on different data sheets. Knowing which method produced a number tells you whether two products can be compared at all.
| Property | Test method | Method title | What the buyer learns |
|---|---|---|---|
| Elongation and tensile strength | ASTM D2370 | Tensile Properties of Organic Coatings | How far the film stretches before breaking and how much force it takes. The method built for coatings. |
| Elongation (wrong method for coatings) | ASTM D412 | Vulcanized Rubber and Thermoplastic Elastomers, Tension | Intended for prefabricated rubber sheet. Kirn flagged its use on coatings in 2001. Numbers from D412 and D2370 are not interchangeable. |
| Permeance | ASTM D1653 or ASTM E96 | Water Vapor Transmission of Organic Coating Films / Gravimetric Determination of Water Vapor Transmission Rate | Whether the film breathes. Acrylic sheets usually cite D1653, silicone sheets often cite E96. |
| Volume solids | ASTM D2697 | Volume Nonvolatile Matter in Clear or Pigmented Coatings | How much dry film you get per gallon. The single best value for comparing cost per mil. |
| Weight solids | ASTM D1644 | Nonvolatile Content of Varnishes | Easier to measure than volume solids and easier to inflate with heavy filler. |
| Accelerated weathering | ASTM D4798 | Accelerated Weathering Test Conditions and Procedures for Bituminous Materials (Xenon-Arc Method) | Whether the film cracks or checks after a fixed exposure. Hours matter: 1,000 and 5,000 hour results are not comparable. |
| Adhesion (peel) | ASTM D903 or ASTM C794 | Peel or Stripping Strength of Adhesive Bonds / Adhesion-in-Peel of Elastomeric Joint Sealants | Force to peel the film off the substrate. Ask whether the reported value is dry or wet. |
| Tear resistance | ASTM D624 | Tear Strength of Conventional Vulcanized Rubber and Thermoplastic Elastomers | How fast damage propagates once the film is nicked or has already delaminated. |
| Low temperature flexibility | ASTM D522 | Mandrel Bend Test of Attached Organic Coatings | Whether the aged film cracks when bent cold. Always check the stated mandrel size and temperature. |
| Water swelling | ASTM D471 | Rubber Property, Effect of Liquids | How much water the film absorbs. Swelling stresses the bond line. |
| Fungi resistance | ASTM G21 | Determining Resistance of Synthetic Polymeric Materials to Fungi | Appearance retention. Biocides leach out over time, fastest where water stands. |
| Hardness | ASTM D2240 | Rubber Property, Durometer Hardness | Shore A value. Informational, not a D6083 pass criterion. |
| VOC content | ASTM D3960 | Determining Volatile Organic Compound (VOC) Content of Paints and Related Coatings | Whether the product is legal in your air district. |
How to read a roof coating data sheet against the standard
A compliant data sheet prints three columns: the test method, the ASTM minimum, and the manufacturer’s measured value. Anything less is a claim rather than a disclosure. Work through it in this order.
- Find the specification header, not the marketing line. Look for a heading like “Physical Properties (ASTM D6083)” above the table. A bullet in the sales copy saying “meets ASTM standards” with no table behind it is not evidence of anything.
- Check the revision year. GAF’s Acrylic Top Coat sheet heads its table “ASTM D6083-21” while the active version is D6083/D6083M-24. Older revisions can carry different requirements.
- Read the type designation. D6083 pass claims should name Type 1 or Type II. The type drives the volume solids floor and the low temperature flexibility threshold.
- Compare the measured column against the minimum column, value by value. GAF’s High Tensile Acrylic Top Coat publishes 500 percent initial elongation against a 100 percent minimum and 550 psi tensile against a 200 psi minimum, per its published data sheet. That is a coating clearing the floor by roughly five times and nearly three times.
- Flag every cell that says “Pass” or “Meets ASTM D6083” instead of a number. On GAF’s standard Acrylic Top Coat sheet, elongation, tensile and permeance are all reported as “Pass” or “Meets ASTM D6083” rather than as measured values. The product is compliant. You simply cannot rank it against a competitor on those rows.
- Check the permeance direction. On acrylic sheets permeance is a maximum (GAF cites max 50 perms under D1653, with a measured 2.5 perms at 20 mils). On GAF’s silicone sheet it appears as a minimum of 2.5 perms under E96, with a measured 6.19 perms. A high number is good in one context and disqualifying in the other.
- Check the weathering hours. GAF’s acrylic sheet reports 1,000 hour accelerated weathering; its silicone sheet reports 5,000 hours. Both pass. They are not the same test.
- Confirm the coverage rate the numbers assume. Film properties are measured at a stated dry film thickness. A data sheet value at 20 mils tells you nothing about a job applied at 12.
One instructive comparison: two acrylic top coats from the same manufacturer, both claiming D6083, disclose at completely different depths. One prints hard numbers on every row. The other prints “Pass.” Same standard, same brand, different amount of information transferred. That gap, not the standard itself, is where most coating buying decisions are actually lost. Our roof coating types comparison covers how those chemistries differ on cost and service life once you are past the spec sheet.
Why a coating can meet D6083 and still fail in ponding water
D6083 has no ponding test. Its water resistance requirements are permeance (ASTM D1653) and water swelling (ASTM D471), both run on a free film in a lab, plus a wet adhesion requirement. Standing water on a roof attacks a different property: the bond between coating and substrate, under continuous saturation, at whatever temperature the roof reaches.
Kirn made the point directly in the IIBEC paper: the roofing industry keeps asking whether a coating withstands ponded water, but the question is better restated as how good the wet adhesion is. A film can swell within limits, pass permeance and still release from an aged substrate once water sits on it for weeks. Fungi resistance degrades on the same schedule, because the biocides leach fastest where water stands.
This is the practical reason silicone dominates ponding specifications while acrylic is generally written for positive drainage. It is a chemistry outcome, not something the D6083 pass or fail decides. If drainage is the issue, the fix is drainage and chemistry selection together, which is where the silicone versus acrylic decision gets made.
What the coating specifications do not cover at all
ASTM D6083, D6694 and D6947 are material specifications. Three properties buyers assume are included sit entirely outside them, and each has its own standard and its own listing body.
- Fire classification. Roof covering fire performance runs through ASTM E108 and its UL equivalent, ANSI/UL 790, and it is an assembly rating, not a coating rating. GAF’s silicone data sheet points to UL Product iQ for the actual listed assemblies. See our breakdown of what qualifies as a Class A fire rated roof.
- Wind uplift. No coating specification includes an uplift value. Uplift is tested at the assembly level, with FM Approvals listings referenced through RoofNav, and field verification of adhered systems done under ASTM E907, Field Testing Uplift Resistance of Adhered Membrane Roofing Systems.
- Reflectivity and cool roof compliance. Solar reflectance is measured under ASTM C1549, thermal emittance under ASTM C1371, and Solar Reflectance Index is calculated under ASTM E1980. Aged values come from Cool Roof Rating Council ratings, with laboratory soiling simulated under ASTM D7897. GAF’s High Solids Silicone, CRRC ID 0676-0160, lists initial solar reflectance of 0.88 and initial SRI of 112 on a smooth substrate, dropping to 0.69 reflectance and SRI 85 on the aged rapid rating. Our solar reflectance and SRI reference compares measured values across roof types.
Substrate standards are separate again. Spray polyurethane foam itself is specified under ASTM C1029, Spray-Applied Rigid Cellular Polyurethane Thermal Insulation, which classifies the foam into four types by density and compressive strength. A D6694 silicone over an out of spec foam is a compliant coating on a noncompliant substrate. The SPF roofing guide covers how those two specifications stack.
Frequently asked questions
What does ASTM D6083 mean on a roof coating?
It means the acrylic coating was tested against the minimum liquid and film property requirements in ASTM D6083/D6083M-24, covering solids, elongation, tensile strength, permeance, water swelling, adhesion, fungi resistance, tear resistance and low temperature flexibility. It certifies laboratory material properties on a free film. It says nothing about installed thickness, substrate preparation, drainage, or how long the coating will last on a specific roof.
Is ASTM D7311 the SEBS roof coating standard?
No. ASTM lists D7311 as the specification for a liquid applied, single pack, moisture triggered, aliphatic polyurethane roofing membrane, and it was withdrawn in 2013. There is currently no published ASTM specification for liquid applied SEBS roof coating. A draft is in progress as ASTM work item WK85130. The only published ASTM standard naming SEBS is D6152, which covers SEBS modified mopping asphalt, not a coating.
What is the difference between ASTM D6083 and ASTM D6694?
D6083 governs water dispersed acrylic latex coatings used in roofing generally. D6694 governs solvent dispersed coatings containing more than 95 percent silicone polymer, written specifically for use as a membrane over spray polyurethane foam. They also differ on permeance direction: acrylic sheets typically report permeance against a maximum limit, while silicone sheets commonly report it against a stated minimum.
Which ASTM standard covers polyurethane roof coatings?
ASTM D6947/D6947M-16(2023) covers single component, moisture cured elastomeric urethane coatings used as protective coatings over spray polyurethane foam roofing systems. Its requirement list is close to the acrylic and silicone specifications: viscosity, volume and weight solids, elongation, tensile strength, elongation after accelerated weathering, permeance, water absorption, adhesion, fungi resistance, tear resistance and low temperature flexibility.
Do ASTM coating standards cover wind uplift or fire rating?
No. Wind uplift and fire classification are assembly properties, not coating properties. Fire runs through ASTM E108 and ANSI/UL 790 as a listed assembly. Uplift is handled through FM Approvals assembly listings and field verified on adhered systems under ASTM E907. A coating can fully meet D6083 or D6694 and carry no independent fire or uplift rating of its own.
How do I know if a coating really meets the standard it claims?
Ask for the data sheet table that lists the ASTM test method, the ASTM minimum and the manufacturer’s measured value side by side, and check the revision year in the table header. Rows reported as “Pass” or “meets ASTM” instead of a number are compliant but not comparable. For third party confirmation, look for the assembly level listings: UL Product iQ, FM RoofNav, CRRC rated product identification numbers, and code report numbers.
Does meeting ASTM D6083 mean a coating handles ponding water?
No. D6083 includes permeance and water swelling tests on a free film, not a ponding test. The property that governs performance under standing water is wet adhesion between the coating and the substrate. Acrylic systems are generally specified for roofs with positive drainage, while silicone is the usual choice where water stands. Correcting drainage is normally part of the fix, not optional.
Are ASTM roof coating test results third party verified?
Usually not. Values in a data sheet ASTM table are typically the manufacturer’s own or contracted laboratory results, reported voluntarily. ASTM writes the specification, it does not certify products or audit compliance. Third party verification comes from separate programs: Cool Roof Rating Council ratings for reflectance and emittance, UL and FM listings for fire and uplift assemblies, and ICC ES or Miami-Dade product approvals.
