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
1. Scope
1.1 This test method covers the determination of the non- volatile matter in volatile solvents for use in paint, varnish, lacquer, and related products. 1.2 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 For hazard information and guidance, see the supplier’s Material Safety Data Sheet for materials listed in this test method. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 5. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Significance and Use
3.1 This test method describes the analytical measurement of residual matter in solvents that are intended to be 100 % volatile at 105 °C 6 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 efficiency of the process. This test method is useful in manufacturing control and assessing compliance with specifications.
4. Apparatus
4.1 Oven, thermostatically controlled at 105 °C 6 5 °C. 4.2 Dish, evaporating, platinum, 125-mL. A platinum evaporating dish is preferred. Alternatively, an aluminum or porcelain dish may be used (see Note 1). N OTE 1—Precision data were determined utilizing only platinum dishes. 4.3 Cylinder, graduated, 100-mL. 4.4 Analytical Balance, precision to 60.1 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 perox- ides may present a violent explosion hazard when the chemi- cals are evaporated. When peroxide formation is likely because ofchemical type or length ofstorage time, analyze the material for peroxides (see Test Method E299). If they exist in hazard- ous concentrations, take appropriate precautions such as de- stroying the peroxides before evaporation, shielding, or dis- posal 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 6 5 °C, cool in a desiccator, and weigh. Repeat until the weight is within 0.1 mg of the previous weighing. 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 be used. N OTE 2—Precision data were obtained only with evaporation using steam bath. 6.3 Return the dish and contents to the oven for 15 to 30 min, cool, and reweigh. Repeat, ifnecessary, until the weight is constant to within 0.1 mg of the previous weighing.Repeatability Limit (r)—Two test results obtained within one laboratory shall be judged not equivalent if they differ by more than the “r” value for that material; “r” is the interval representing the critical difference between two test results for the same paint, obtained by the same operator using the same equipment on the same day in the same laboratory.
