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.
1.1 This test method covers the determination of the nonvolatile 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 he rounded oft’“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.
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 ± 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 etliciency 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 ± 5 °C.
4.2 Dish, evaporating, platinum. 125—mL. A platinum evaporating dish is preferred. Alternatively, an aluminum or porcelain dish may he used (see Note 1).
Note 1—Precision data were determined utilizing only platinum dishes.
4.3 Cylinder graduated. 100-mL.
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 violent explosion hazard when the chemicals 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 of the previous weighing.ASTM D1353 pdf download.
