Procedure4.1 Aerosol CoatingsTest Method D 3062 covers thedetermination of solids content (weight %) in aerosol coatings.4.2 Volatile Content of Coatings (Test Method D 2369)This test method covers the determination of
16、 the volatilecontent of coatings. It is considered to be applicable to mostsolvent-reducible and water-reducible paints.4.3 High Performance Interior Architectural Wall Coatings(HIPAC)Determine the nonvolatile content of HIPAC coat-ings in accordance with Test Methods D 1644. Calculate thevolatile c
17、ontent (weight %) by difference.4.3.1 Method A3 h at 105C for paints with nonsolventcomponents that decompose at higher temperature.4.3.2 Method B10 min at 149C for most paints withnonsolvent components that are reasonably stable at 149C.4.4 Asphalt Roof CoatingsDetermine the nonvolatile con-tent (w
18、eight %) of asphalt roof coatings of brushing or spray-ing consistency in accordance with the Physical RequirementsConsistency section of Specification D 2823.4.5 Aluminum-Pigmented Asphalt Roof CoatingsThenonvolatile content (weight %) of asphalt-based aluminumroof coatings suitable for application
19、 to roofing or masonrysurfaces by brush or spray is determined in accordance with thePhysical Requirements Consistency section of SpecificationD 2824.4.6 Emulsified Bitumens Used as Protective CoatingsSection 8 of Test Methods D 2939 contains a method fordetermining residue by evaporation (weight %)
20、 of emulsifiedbitumens used in relatively thick films as protective coatingsfor metals and built-up roofs.4.7 Shellac VarnishDetermine the nonvolatile matter inorange shellac and bleached lac varnishes in accordance withSections on Drying Time Procedure and Nonvolatile MatterMaterials and Procedure
21、sections of Methods D 1650.4.8 Coil CoatingsAlthough stated to be for solvents,determine the nonvolatile matter (weight %) in accordancewith Test Method D 1353.

22、nificance and Use,Apparatus, and Procedure of Test Methods D115on nonvola-tile matter by weight, are applicable to the following classifi-cations of varnishes used for electrical insulation: alcohol-soluble varnishes, oxidizing air-drying varnishes,thermosetting varnishes, oxidizing baking varnishes
23、, air-dryingasphaltic varnishes, silicone varnishes, and thermo-settinglaminating varnishes.4.9.2 Determine nonvolatile matter in electrical insulatingvarnishes intended for electrical equipment operating at 180Cand above in accordance with Test Methods D115except thatthe temperature used shall be 1
24、35 6 3C (275 6 5.5F) or ata temperature agreed upon between the producer and the user.4.10 Volume Nonvolatile Matter in Clear or PigmentedCoatings (Test Method D 2697) This test method is appli-cable to the determination of the volume nonvolatile matter ofcoatings. A gloss enamel, a flat wall paint,

As an additional
26、 requirement, the specimen shall bereheated and reweighed until the weight is constant to within 1mg. Method A of Test Methods D 1644 is preferred sinceMethod B is potentially dangerous when used with lacquers.4.12 Magnet Wire EnamelsThe Determined Solids andStack Loss sections of Test Method D 3288

31、 Test Methods D 1644. These testmethods may give high results due either to incompleteelimination of volatile matter or to absorption of oxygen byoxidizing-type varnishes.4.17 Solvent-Based Interior Semigloss Wall and TrimEnamelsUse Test Method D 2369 to determine volatilecontent. Volume nonvolatile
