IICharacteristic values and uncertainties

thisseriesThe uncertainty assessment of the characteristic values of standard substances mainly considers the uncertainty components introduced by the joint determination of multiple laboratories, as well as the uncertainty components introduced by the uniformity and stability tests of standard substances.

IIIUniformity testing and stability assessment

Reference standard materialrelatedTechnical specifications require randomly selecting standard substance samples after packaging,Reference standardsGB/T42696-2023The conditions for the determination of phosphate ester compounds in textiles,adoptUltrasonic extraction with ethyl acetate60min，gas chromatography-Tandem mass spectrometry（GC-MS）Conduct uniformity and stability tests,RMX-E019The minimum sampling size is0.2g；RMX-E020The minimum sampling size is0.1gThe results indicate that the series of standard materials have good uniformity and stability. The validity period of this standard substance is from the date of self determination3Year. The research and development unit will continue to track and test the stability of the standard substance. If any changes in the value are found within the validity period, the user will be notified in a timely manner.

4Traceability and value determination methods

This standard substance is calibrated using a joint calibration method from multiple laboratories. The calibration method is as follows:Ultrasonic extraction with ethyl acetate60min，gas chromatography-Tandem mass spectrometry（GC-MS）Measurement solutionBy using measurement methods and instruments that meet the requirements of metrological characteristics, the traceability of characteristic values of standard substances is ensured.
