“This standard is no longer an American National Standard or an ASME-approved standard. It is available for historical reference only.”

This standard presents graphic symbols for plumbing fixtures for use on drawings created by architects, engineers and plumbing contractors. Included in Section 5 are symbols for the more common fixtures found in the average building. Included in Section 6 are symbols for the special types of fixtures utilized in hospitals and institutions. By the use of these symbols on their plans, designers and builders will have a uniform method for indicating plumbing fixtures and related items. Drawings will thus be more concise and more easily understood.
