自2010年5月起，本文件已被标为“已取消”。通过这一行动，本文件将保留在航空航天标准索引的数字部分。本SAE航空航天推荐规程（ARP）描述了灰尘控制空间中颗粒取样的两个程序。其中一个步骤涵盖5gmm以上的空气粉尘。另一个（以及新添加的程序）包括25gmm及更大的颗粒，这些颗粒会从环境中“脱落”到表面上。在每种情况下，粒子都是按最长的尺寸进行大小调整和计数的。空气中的颗粒物报告为每立方米（立方英尺）的颗粒物，而在脱落样品中收集的颗粒物报告为每0.1平方米（平方英尺）的颗粒物。本文件包括括号内的英语单位，作为有意义的国际单位制参考信息。

This document has been decalred "CANCELLED" as of May 2010. By this action, this document will remain listed in the Numercial Section of the Aerospace Standards Index.This SAE Aerospace Recommended Practice (ARP) describes two procedures for sampling particles in dust controlled spaces. One procedure covers airborne dust above 5 \gmm. The other (and newly added procedure) covers particles of 25 \gmm and larger that "fall out" of the environment onto surfaces. In each case the particles are sized in the longest dimension and counted. Airborne particles are reported as particles per cubic meter (cubic foot) whereas particles collected in fall out samples are reported as particles per 0.1 square meter (square foot). This document includes English units in parentheses as referenced information to the SI units where meaningful.
