ASTM D1353:13(R2021) pdf free download – Standard Test Method for Nonvolatile Matter in Volatile Solvents for Use in Paint, Varnish, Lacquer, and Related Products.
3. Significance and Use
3.1 This test method describes the analytical measurement of residual matter in solvcnts that arc intended to be 1(X) % volatile at 105 °C ± 5 °C. Volatile solvents are used in the manufacture of paint, varnish. lacquer, and other related products, and the presence of any residue may affect the product quality or cfficicncy of the process. This tcst mcthod is useful in manufacturing control and assessing compliance with specilications.
4. Apparatus
4.1 O’en. thermostatically controlled at 105 °C ± 5 °C.
4.2 Dish, evaporating, platinum. l25-mL. A platinum evaporating dish is preferred. Alternatively, an aluminum or porcelain dish may be used (see Note I).
Note 1–Preckion daia were dctennincd utilirmg only platinum dishes.
4.4 Analytical Balance, precision to ±0.1 mg.
5. hazards
5.1 Warning—Certain solvents and chemical intermediates, particularly. but not only ethers and unsaturated compounds. may form peroxides during storage. These peroxides may present a violcnt explosion hazard when the chcmicals are evaporated. When peroxide formation is likely because of chemical type or length of storage time, analyze the material for peroxides (see Test Method E299). If they exist in hazardous concentrations, take appropriate precautions such as destroying the peroxides before evaporation. shielding, or disposal of the sample and not running the test.
6. Procedure
6.1 Dry a 125-mL platinum evaporating dish in an oven at 105 °C ± 5 °C. cool in a desiccator, and weigh. Repeat until the weight is within 0.1 mg 1)1 the previous wcighing.
6.2 With the graduated cylinder, measure 100 mL of sample at room temperature into the conditioned platinum evaporating dish (see 4.2); place on a steam bath or a hot plate in a fume hood and evaporate. Warning—Since aliphatic hydrocarbons have low autoignition temperatures. only efficient hoods should he used.
Note 2—Precision data were obtained only with cviaptwatlon LoSIng steam bath.
6.3 Return the dish and contents to the oven for IS to 30 mm, cool, and reweigh. Repeat, if necessary. until the weight is constant to within 0.1 mg of the previous weighing.
7. Report
7.1 Report as nonvolatile matter the residue obtained from the specimen as milligrams of nonvolatile residue/lOO mL.
