Specification forms make provision for key data of the equipment and its position in the process, including design characteristics and required performance. A major purpose is a basis for price quotations by suppliers of the equipment.

Although a few forms have been prepared by industry-wide organizations such as TEMA, Hydraulic Institute, and API, most have been prepared for their own use by engineering contractors and design divisions of chemical process organizations. Most private firms have their own libraries, but the merits of some forms have been recognized and copied widely so that much uniformity exists.

The selection of forms in this Appendix is made available through the courtesy of individual companies identified on each form, although one major contributor did not wish to be identified. For the most part, only the most often used kind of equipment is represented, except for the few items in category K.

A related kind of information is the suppliers inquiry forms of Appendix C.

Following is a listing of the equipment specification forms, included in this Appendix. The number appearing in italic is the page number on which the form appears.
