Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent.Within the API naming convention, standards may be designated as “specifications”, “recommended practices”, or “standards”. A “specification” is a do
14、cument written to facilitate communications between purchasers, manufacturers, and/or service suppliers. Specifications may include datasheets that may be used in industrial transactions. A “recommended practice” is a document that communicates recognized industry practices. Recommended practices ma
15、y include both mandatory and non-mandatory requirements. A “standard” is a document that combines elements of both specifications and recommended practices.Shall: As used in a recommended practice, “shall” denotes a minimum requirement in order to conform to the Recommended Practice (RP).Should: As
16、used in a recommended practice, “should” denotes a recommendation or that which is advised but not required in order to conform to the RP.This document was produced under API standardization procedures that ensure appropriate notification and participation in the developmental process and is designa
17、ted as an API standard.
