Abstract

Because a sample must be representative to be of any value, the method of sampling is of major importance in testing and inspection. Much time and description is devoted to the details of test methods, but almost no exacting instructions have been prepared covering the correct procedure for securing representative samples. The reason for this deficiency is primarily that the conditions and situations involved in taking samples in the field are so varied that complete and detailed instructions would necessarily be too voluminous and complex. In this paper some of the conditions and situations are described and some general precautions stated. Equipment for sampling is discussed.
