PURPOSE AND USE OF PROCESS INDUSTRY PRACTICES

In an effort to minimize the cost of process industry facilities, this Practice has
been prepared from the technical requirements in the existing standards of major
industrial users, contractors, or standards organizations. By harmonizing these technical
requirements into a single set of Practices, administrative, application, and engineering
costs to both the purchaser and the manufacturer should be reduced. While this Practice
is expected to incorporate the majority of requirements of most users, individual
applications may involve requirements that will be appended to and take precedence
over this Practice. Determinations concerning fitness for purpose and particular matters
or application of the Practice to particular project or engineering situations should not
be made solely on information contained in these materials. The use of trade names
from time to time should not be viewed as an expression of preference but rather
recognized as normal usage in the trade. Other brands having the same specifications
are equally correct and may be substituted for those named. All Practices or guidelines
are intended to be consistent with applicable laws and regulations including OSHA
requirements. To the extent these Practices or guidelines should conflict with OSHA or
other applicable laws or regulations, such laws or regulations must be followed.
Consult an appropriate professional before applying or acting on any material
contained in or suggested by the Practice.

This Practice is subject to revision at any time.

Appendix B – Cover Sheets


B-1: Symbols and Nomenclature – Typical Piping
B-2: Symbols and Nomenclature – Typical Instrumentation
B-3: Symbols and Nomenclature – Typical Equipment
B-4: Typical Details with Implied Components



Note: The example cover sheets in this Appendix are not all-inclusive of the potential uses of implied
components. The implied component examples shown do not cover all actual occurrences or
design possibilities for instrument assemblies, such as the level bridles shown. The user must
ensure that the cover sheets capture their piping/instrument requirements for their use of
implied components. There are many more systems that may require a cover sheet explanation
to show the implied components – pump seals, sampling systems, analyzer systems for
example, as well as other types of level systems than those shown here.
