CSA 6.9:2014 pdf download.Quick disconnect devices for use with gas fuel appliances
1.1 CSA 6.9 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. These devices shall be capable of operation at ambient temperatures between 320F to 200F (0C to 93.30C) if intended for indoor use only, or temperatures between -20F to 200°F (-28.80C to 93.30C) if intended for indoor/outdoor use. These devices shall also be capable of operation at temperatures of -400F (-40°C) when so specified by the manufacturer.
1.2 This Standard applies to quick disconnect devices for use with natural, manufactured and mixed gases,propane gas and LP gas-air mixtures, having maximum gas pressure ratings of up to and including 60 psi (414 kPa). A manufacturer must specify what pressure will be marked on the product and the applicable pressures in the performance tests shall be adjusted to meet the testing requirements.
1.6 This Standard contains SI (Metric) corresponding to the yard/ pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (Standard for use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI 10 or ISO 80000-1:2009 Quantities and units-Part 1:General are used as a guide in making metric conversion from yard/ pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both shall be provided.
4.4.2 The design of the device shall be such that continuous leakage from the supply side will not occur during connection and disconnection of the mating parts or when the mating parts are only partially joined.Leakage shall be determined as specified in Clause 5.1, Leakage.
The inlet ends of completely assembled devices shall be attached to a rigidly supported extra heavy pipe manifold so that they will be horizontal. The weight specified above shall then be suspended from the extreme outlet end of the assembled device without shock. At the end of 15 minutes the device shall be subjected to the leakage tests specified in Clause 5.1, Leakage. The weight shall be removed, the device examined for deformation and breakage and again subjected to the leakage test specified in Clause 5.1.CSA 6.9 pdf download.
