36、ITTINGS CERTIFICATIONADMINISTRATION0 IntroductionThe purpose of this standard is to provide guidance for theadministration of the API Tank Seals and Fittings Certifica-tion Program. Detailed requirements for this program arespecified in other parts of APIs Manual of Petroleum Mea-surement Standards(

37、MPMS), Chapter 19.3, as listed in thereference section below. The standards of the API MPMS,Chapter 19.3, collectively describe the certification programby which petitioners may have the evaporative loss factors ofproprietary floating-roof devices measured by laboratoriesthat are registered with API

38、 for that purpose.It is not the purpose of the certification program to specifyprocedures to be used in the design, manufacture, or fieldinstallation of floating-roof rim seals or deck fittings. Further-more, equipment should not necessarily be selected for usesolely on the basis of evaporative-loss

39、 considerations. Manyother factorssuch as tank operation, maintenance, andsafetyare important in designing and selecting tank equip-ment for a given application.1 ScopeThis standard illustrates how other standards of the APIMPMS, Chapter 19.3, referenced below, are integrated intothe overall certifi

40、cation program, and it presents proceduresfor the evaluations to be performed by API under this pro-gram. These evaluations include review of the start-up docu-mentation for registered testing laboratories, approval ofproposed protocol testing for individual devices, monitoringof the tests, and anal

41、ysis of test results.This standard may involve hazardous materials, operations,and equipment. This standard does not purport to address allof the safety problems associated with its use. It is the respon-sibility of the user of this standard to establish appropriatesafety and health practices and de

42、termine the applicability ofregulatory limitations prior to use.2 ReferencesThe most recent editions of the following standards containprovisions that, through reference in this text, constitute a partof this standard.API Manual of Petroleum Measurement Standards(MPMS)Chapter 15“Guidelines for the U

This annular space is closed by a flexi-ble device called a rim seal.
