GB/T 39527-2020 (English Version) PDF

Scope: This standard specifies the method principles, reagents and equipment, test methods and requirements, precision and inspection reports for the determination of calcium, aluminum and silicon element content in solid surface products by chemical titration and inductively coupled plasma emission spectrometry. This standard is applicable to the determination of calcium, potassium and silicon content in solid surface products. Artificial granite and artificial quartz stone can be used as a reference. The measurement range of each element of solid surface material products is shown in Table 1. Table 1 Elements and measuring range Element name Measuring range Mass fraction)/Bar Calcium (calculated as CaO) 0.51 to 51.45 Aluminum (calculated as AbOs) 0.50 to 48.96 Silicon (calculated as SiO) 0.53 to 90.49 The specified measurement range indicates precision The range that has been studied experimentally. It may be applicable beyond this range, but the laboratory needs to verify the testing beyond the range.
