浅谈《化妆品安全技术规范》理化检验结果的数值修约

Discussion on Rounding off the Cosmetics Physical and Chemical Test Results of Safety and Technical Standards for Cosmetics

为建立化妆品理化检验结果的修约方法,根据GB/T 8170-2008《数值修约规则与极限数值的表示和判定》的要求,确定各参数的有效位数,按有效数字运算规律进行运算,对《化妆品安全技术规范》中理化检验结果进行修约。结果发现:化妆品理化检验结果可保留2或3位有效数字,所建立的方法适用于对《化妆品安全技术规范》(2015年版)理化检验结果的修约。

To establish the rounding method applied to cosmetics physical and chemical test results,according to GB/T 8170—2008 rules of rounding off for numerical values&expression and judgment of limiting values,the test results were rounded following the rules for retention of significant digits.It was showed that the test results should have two or three significance digits.The method established in this study is suitable for rounding numerical values of Safety and Technical Standards for Cosmetics 2015.
