摘要
介绍无焰燃烧烟密度标准物质的研制方法。选用合适的α-纤维素作为原材料,经打浆造纸后,作为标准物质候选物,经均匀性检验和稳定性考察合格后,对标准物质进行定值。在无焰燃烧条件下烟密度标准物质的标准值为175,扩展不确定度为8;校正烟密度标准物质的标准值为166,扩展不确定度为8。
Non-flame smoke density certified reference material was development. It was made of a-cellulose, The homogeneity and stability of non-flame smoke density certified reference material were satisfied, Under the condition of non-flame, the standard values were 175 for smoke density and 166 for the calibration smoke density, the expanded uncertainties were 8 for smoke density and calibration smoke density.
