scope:
This standard shall be used to measure and assess the ability of ground supported, flat bottom steel suction tanks to provide a highly reliable source of water for fire protection at anticipated rates and durations in emergency situations. Such tanks shall be permitted to utilize either bolted or welded shell plate designs as submitted by the manufacturer.
The standard shall also be used to measure and assess the ability of steel gravity tanks on steel towers (also referred to as elevated tanks in this document) to provide fire protection water as noted above. Such tanks shall utilize welded steel plate designs as submitted by the manufacturer.
The items addressed by this standard are limited to the tank proper, its foundation, penetrations and related appurtenances. Excluded from the scope of this standard are pumps, pump houses, internal and external piping and any item not specifically addressed.
This standard is not intended to determine the suitability for all end use conditions of a product as conditions under which tanks are used vary widely. This standard therefore, does not evaluate every condition or environment to which a suction tank might be exposed.
All tanks addressed in this standard shall be fabricated from carbon steel. All ground-supported suction tanks shall be cylindrical in shape. Elevated tanks shall be permitted to be elliptical, hemispherical or conical in shape.
Purpose
This standard states Approval requirements for steel tanks used for fire protection.
Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
