Pilot Gas Filters
This standard applies to newly produced pilot gas filters, hereinafter referred to as filters (See Part IV, Definitions), constructed entirely of new, unused parts and materials. Compliance of a filter with this standard does not imply that the filter is acceptable for use on gas appliances without supplemental tests with the filter applied to the particular appliance design.
