CSA/AM - ANSI Z21.81/CSA 6.25
Cylinder Connection Devices
|Publication Date:||1 January 1997|
This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of cylinder connection devices. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on cylinder connection devices designed for utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to help reduce such risks while retaining the normal operation of the appliance.
Nothing in this standard is to be considered in any way indicating a measure of quality beyond compliance with the provisions it contains. It is designed to allow compliance of cylinder connection devices, the safety construction and performance of witch may exceed the various provisions specified herein. In its preparation, full recognition has been given to possibilities of improvement through ingenuity of design. As progress takes place, revisions may become necessary. When they are believed desirable, recommendations or suggestions should be forwarded to the Chairman of Accredited Standards Committee Z21/Z83, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Chairman (Interim CSA) Gas Equipment Standards Steering Committee, 178 Rexdale Boulevard, Etobicoke Ontario, Canada M9W 1R3.
Safe and satisfactory operation of a cylinder connection devices depends to a great extent upon its proper installation, use and maintenance. It should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI Z223.1; the Natural Gas Installation Code, CAN/CGA-B149.1; the Propane Installation Code, CAN/CGA-B149.2.
Users of this American National Standard/CSA Gas Standard are advised that the devices, products and activities within its scope may be subject to regulation at the Federal, Territorial, Provincial, state or local level. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a conflict with this standard, the Federal, Territorial, Provincial, state or local regulation should be followed.
THIS STANDARD IS INTENDED TO BE USED BY THE MANUFACTURING SECTOR AND BY THOSE APPLYING THE EQUIPMENT AND BY THOSE RESPONSIBLE FOR ITS PROPER INSTALLATION. IT IS THE RESPONSIBILITY OF THESE USERS TO DETERMINE THAT IN EACH CASE THIS STANDARD IS SUITABLE FOR AND APPLICABLE TO THE SPECIFIC USE THEY INTEND.
