This specification establishes the material, design, and performance requirements pertinent to the construction of commercial pulping and waterpress assemblies that are intended for grinding food scraps, paper, cardboard, and disposable plastic food-service ware. Unless otherwise specified, materials used to fabricate pulpers and waterpresses may include corrosion-resistant steel and other corrosion-resisting materials, abrasion-resistant cast iron, austenitic gray iron, copper tube, brass pipe, alloy steel, black and galvanized pipe, gaskets and seals, perforated metal, stainless steel pipe, plastic piping and fitting, and austenitic gray iron pipe fitting. Assembled pulpers and waterpresses shall meet operational, electrical, lubrication, finish, and performance requirements, and should function satisfactorily as specified.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers commercial pulping and waterpress assemblies intended for grinding of food scraps, paper, cardboard, and disposable plastic food-service ware.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 The following safety hazards caveat pertains only to the test method portion, Section 13, of this specification: This standard does not purport to address all of the safety concerns, 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.
