Preface

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of quick disconnect devices for use with gas fuel appliances. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on quick disconnect devices for use with gas fuel appliances 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.

The revisions in this standard supersede any corresponding provisions of ANSI Z21.41-2003 (R2008)-CSA 6.9-2003, ANSI Z21.41a-2005 (R2008)-CSA 6.9a-2005, and ANZI Z21.41b-2010-CSA 6.9-2010; and are identical to the coverage from the review and comment text dated October 2009, distributed during that period.

Scope

1.1.1
This standard applies to newly-produced, hand-operated quick-disconnect devices, hereinafter also referred to as devices, constructed entirely of new, unused parts and materials which provide a means for connecting and disconnecting appliances or appliance connectors to gas supplies and which are for indoor and outdoor applications. These devices shall be equipped with automatic means to shut off the gas when the devices are disconnected. The mating parts shall be held together securely either by a positive locking means or by means requiring a straight pull to disconnect.

1.1.2
This standard applies to devices for use with natural, manufactured and mixed gases, liquefied petroleum gases and LP gas-air mixtures, at pressures not in excess of 1/2 psi (3.5 kPa).

1.1.3
All references to psi (kPa) throughout this standard are to be considered as gauge pressure unless otherwise specified.

1.1.4
Exhibit A, Items Unique to Canada, contains provisions that are unique to Canada.

1.1.5
Exhibit B, List of Reference Standards, contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
