ASTM F1217-92(1997)
(Specification)Standard Specification for Cooker, Steam
Standard Specification for Cooker, Steam
SCOPE
1.1 This specification covers food cookers and food reheaters which use steam as the heat source. These units are also known as steamers, steam ovens, and steam cookers and are for use in commercial and institutional food service establishments. This specification can be used for zero-pressure steam cookers, pressure steamers, and combination pressure/pressureless steamers and does not cover steam cooking equipment used by food processors who normally package the food that they cook.
1.2 The values stated in inch-pound units are to be regarded as the standard.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
