测量及计数表面上微粒污染物的试验方法

Standard Test Method for Measuring and Counting Particulate Contamination on Surfaces

适用范围:<p id="s00002">1.1 This test method covers the size distribution analysis of particulate contamination, 5 <span class=''unicode''>x03BC;</span>m or greater in size, either on, or washed from, the surface of small electron-device components. A maximum variation of two to one (<span class=''unicode''>x00B1;</span>33 % of the average of two runs) should be expected for replicate counts on the same sample.</p> <p id="s00888">1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.</p>
