The Comparison of Ultraviolet Regular Transmittance

中文摘要英文摘要

为保证我国紫外透射量值与国际的一致性,中国计量科学研究院代表我国参加了在2018年至2019年间,欧亚计量合作组织(COOMET)组织的首次紫外透射比的研究性比对.这次比对采用了 4组溶液作为比对样品,透射比量值标称值覆盖5%~90%,波段覆盖235~350 nm.比对结果表明,各参比实验室测量结果基本一致.在透射比50%附近,我国与距离国际参考值的偏离量最大不超过0.12%;在透射比20%附近,我国与距离国际参考值的偏离量不足0.08%;在透射比10%附近,我国与距离国际参考值的偏离量不超过0.03%.

In order to ensure the consistency of UV transmittance values in China with those in the world,the National Institute of Metrology,China,participated in the first research comparison of ultraviolet regular transmittance organized by COOMET during 2018 to 2019.This comparison uses 4 sets of solutions as comparison samples,the nominal value of transmittance covers 5%~90%,and the wavelength range covers 235 nm~350 nm.The comparison results show that the measurement results of each reference laboratory are basically equivalent and consistent.When the transmittance is 50%,the deviation between ours and the international reference value can not exceed 0.12%.When the transmittance is near 20%,the deviation between ours and the international reference value is less than 0.08%.For 10%transmittance,the deviates quantity is no more than 0.03%.
