KS M 0005-1997 PDF

Scope: This standard specifies about general method to measure refractive index of chemical products. Remarks 1. Chemical products indicate whole materials that are created by chemical reactions, but it follows the specified method in the standard in case the measurement method that is different from the standard of individual product or product group is specified. 2. There are some chemical products that can't secure safety of test because volatility, explosiveness, radioactivity and etc are strong. Specified method in this standard is general method. Apply what can confirm the safety enough previously. 3. Because the refractive index of chemical products uses sodium spectrum D usually, represent by nD20 for air at 20°C. 4. Sample must be homogeneous and transparent liquid or solid, and satisfy the specified condition by the measurement method. 5. This standard specifies the method to yield the value of the refractive index with accuracy of ± 0.0002.
