PURPOSE AND USE OF PROCESS INDUSTRY PRACTICES

In an effort to minimize the cost of process industry facilities, this Practice hasbeen prepared from the technical requirements in the existing standards of majorindustrial users, contractors, or standards organizations. By harmonizing these technicalrequirements into a single set of Practices, administrative, application, and engineeringcosts to both the purchaser and the manufacturer should be reduced. While this Practiceis expected to incorporate the majority of requirements of most users, individualapplications may involve requirements that will be appended to and take precedence overthis Practice. Determinations concerning fitness for purpose and particular matters orapplication of the Practice to particular project or engineering situations should not bemade solely on information contained in these materials. The use of trade names fromtime to time should not be viewed as an expression of preference but rather recognized asnormal usage in the trade. Other brands having the same specifications are equallycorrect and may be substituted for those named. All practices or guidelines are intendedto be consistent with applicable laws and regulations including OSHA requirements. Tothe extent these practices or guidelines should conflict with OSHA or other applicablelaws or regulations, such laws or regulations must be followed. Consult an appropriateprofessional before applying or acting on any material contained in or suggested by thePractice.
