(Specification)Standard Specification for Commercial Coffee Brewers
Standard Specification for Commercial Coffee Brewers
ABSTRACT
This specification covers commercial single cup or batch coffee brewers which are used for brewing coffee in commercial and institutional facilities and does not include residential units. This specification is limited to standard coffee brewers and does not include espresso or specialty coffee drink machines. Materials used in the construction of the machine shall comply with NSF No. 4 and UL Standard 197. Unless otherwise specified, all hardware and fittings shall be corrosion-resistant to ASTM A167 or ASTM A176 or suitably processed to resist corrosion and all threaded parts shall conform to ANSI B1.1.
SCOPE
1.1 This specification covers commercial single cup or batch coffee brewers which are used for brewing coffee in commercial and institutional facilities and does not include residential units. This specification is limited to standard coffee brewers and does not include espresso or specialty coffee drink machines.
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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
