Scheme for the Identification of Piping Systems
|Publication Date:||1 January 1975|
OBJECT AND SCOPE
This Standard is intended to establish a common system to assist in identification of materials conveyed in piping systems. Use of this Standard will promote greater safety and will lessen chances of error, confusion, or inaction in times of emergency.
This scheme concerns only identification of contents of piping systems in industrial and power plants. It does not cover pipes buried in the ground or electrical conduits.
Existing schemes for identification shall be considered acceptable if certified in writing by an authorized federal or state safety official being equal to or better than this recommended scheme.
