[Current]Methods of testing soils for engineering purposes, Method 1.4.2: Sampling and preparation of soils — Selection of sampling or test sites — Stratified random number method
This Standard sets out the method for selecting the location of test or sampling sites where a test site or stockpile is divided into strata from which individual samples or subsamples are to be taken. The method uses random numbers obtained from a random number table (see Table 1) or generated using a suitable electronic calculator or algorithm. The method is based on ASTM D 3665.
