GB/T 6750-2007 《Paints and varnishes - Determination of density - Pyknometer method》 Related products

The standard GB/T 6750-2007 "Determination of Paints and varnish density Specific Gravity bottle method" specifies a detailed method for the determination of the density of Paints, varnishes and related products using Specific Gravity bottles. This standard applies to Coating materials of low to medium viscosity and is measured at a specified temperature to ensure accuracy and comparability. The standard requires that the Specific Gravity bottle be calibrated before the test and that the temperature change does not exceed 0.5 ° C during the test. The measurement results are expressed in grams per millilitre (g/mL), and the test conditions, Specific Gravity bottle type used, test temperature, and measured density values should be recorded in detail in the test report to ensure the accuracy and traceability of the data.
