Draft Scope/Description:

1.1
This Standard applies to internal quick fastener connection for gas appliances, herein after referred to as an Alternative Connection Means (ACM), constructed entirely of new, unused parts and materials. Alternative Connection Means are limited in size up to and including NPS 1inch (DN 25) diameter and a maximum pressure up to and including ½ psi (3.5 kPa).

Alternative Connection Means are intended for the quick assembly of the gas train (i.e., controls and piping) inside an appliance, which is assembled by the appliance manufacturer. Alternative Connection Means are not intended for the direct connection of the appliance to the fuel supply.

1.2
This Standard applies to Alternative Connection Means for use with natural, manufactured, and liquefied petroleum (LP) gases not in excess of ½ psi (3.5 kPa).

1.3
Alternative Connection Means are capable of operation at ambient temperatures between 32 °F to 300 °F (0 °C to 149 °C) if intended for indoor use only, or temperatures between -20 °F to 300 °F (-29 °C to 149 °C) if intended for indoor/outdoor use unless a lower temperature is specified by the manufacturer.

1.4
If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

1.5
All references to psi throughout this Standard are to be considered gauge pressures, unless otherwise specified.

1.6
Clause 2, Reference publications, contains a list of standards specifically referenced in this Standard, and sources from which these reference standards may be obtained.

1.7
In this Standard, “shall” Is used to express a requirement, i.e.: a provision that the use shall satisfy in order to comply with the Standard; “should” Is used to express a recommendation or that which is advised by not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.
