These requirements cover oxy-acetylene or other oxy-fuel-gas torches employed in operations such as welding, brazing and heating.

A torch to be considered a "Gas Saver Type" under this specification shall have an adjustable pilot flame and a suitable means of turning a preadjusted setting of oxygen and acetylene on and off as required (or desired), by means of an operating lever, or other hand operating medium, without disturbing the setting of the valve adjusting screw.

These requirements are based upon records of tests and field experience and are subject to revision as further experience and investigation may show to be necessary or desirable.

A device or product which complies to these requirements will not be acceptable if upon production tests, other features are found to impair the desired results.
