BS ISO 22262-3:2016主要用于定量分析含有石棉的样品
以低于约5%(按重量计)的估计质量分数进行鉴定。ISO 22262的这一部分扩展了通过
在XRD量化之前,使用简单的灰化和/或酸处理程序。ISO 22262的本部分适用于ISO 22262-1中确定的含石棉材料。这个
以下是样品基质的示例:通过ISO 22262-1中的分析检测到石棉的任何建筑材料;弹性地砖、沥青材料、屋面毡和任何其他含有石棉的材料
嵌入有机基质中,使用ISO 22262-1检测到石棉;使用时检测到石棉的墙壁和天花板石膏,无论是否含有骨料
ISO 22262-1。如果基质中含有非石棉状蛇纹石或非石棉状角闪石矿物
假设的XRD峰是?石棉的可能峰值?将代表这些矿物。这
该方法不适用于可能含有石棉的天然矿物或任何
加入这些天然矿物质。该方法仅适用于建筑材料
含有故意添加的商业级石棉(包括透闪石石棉)的样品。ISO 22262的本部分供熟悉X射线衍射方法的分析员使用
以及参考文献[5]和[6]中规定的其他分析方法。这不是我的本意
ISO 22262的一部分,提供基本分析程序的基本说明。交叉引用:ISO 22262-1:2012ISO 22262-2:2014ISO/IEC指南98-3ISO 5725-2ISO 13794:1999ISO 20988:2007NIOSH方法9000NIOSH方法7500JIS A 1481-3:2014购买本文件时可获得的所有现行修订均包括在内。
BS ISO 22262-3:2016 is primarily intended for quantitative analysis of samples in which asbestos has
been identified at estimated mass fractions lower than approximately 5 % by weight.This part of ISO 22262 extends the applicability and limit of detection of quantitative analysis by the
use of simple procedures of ashing and/or acid treatment prior to XRD quantification.This part of ISO 22262 is applicable to the asbestos-containing materials identified in ISO 22262-1. The
following are examples of sample matrices:any building materials in which asbestos was detected by the analysis in ISO 22262-1;resilient floor tiles, asphaltic materials, roofing felts and any other materials in which asbestos is
embedded in an organic matrix and in which asbestos was detected when using ISO 22262-1;wall and ceiling plasters, with or without aggregate, in which asbestos was detected when using
ISO 22262-1.If non-asbestiform serpentine or non-asbestiform amphibole minerals are included in the matrix, the
XRD peaks that are assumed to be?possible peaks of asbestos?will represent these minerals. This
method is not for application to natural minerals that may contain asbestos or any products that
incorporate such natural minerals. This method is intended only for application to building material
samples that contain deliberately added commercial grade asbestos including tremolite asbestos.This part of ISO 22262 is intended for use by analysts who are familiar with X-ray diffraction methods
and the other analytical procedures specified in the References [5] and [6]. It is not the intention of this
part of ISO 22262 to provide basic instruction in the fundamental analytical procedures.Cross References:ISO 22262-1:2012ISO 22262-2:2014ISO/IEC Guide 98-3ISO 5725-2ISO 13794:1999ISO 20988:2007NIOSH method 9000NIOSH method 7500JIS A 1481-3:2014All current amendments available at time of purchase are included with the purchase of this document.
