Significance and Use
5.1 This practice is intended to assist field personnel in obtaining samples from tanks for laboratory analysis. The cost associated with sampling and analysis make it essential that samples be taken correctly before submitting them for chemical analysis, physical testing, or both. Incorrect sampling can invalidate resulting data.
5.2 This practice provides guidance in choosing the sampling technique and equipment suitable for specific situations. It is recommended that this guide be used as a supplement to a written field sampling plan.
1.2 The purpose of this practice is to help field personnel in planning and obtaining samples from vertical and horizontal tanks, open-topped rectangular/square tanks, railroad and truck tankers, vacuum trucks and tanks with multiple compartments using equipment and techniques that will assist in meeting the sampling objectives.
