API MPMS Chapter 19.3, Part H PDF
The purpose of this standard is to specify requirements for the use of the test methods in API’s Manual of Petroleum Measurement Standards (MPMS), Ch. 19.3, Parts A through E to develop evaporative loss factors for floating-roof rim seals, deck fittings, and deck seams (hereinafter referred to as floating-roof devices).
This standard illustrates how other standards of the API MPMS Ch. 19.3 series are integrated into an overall loss factor development program to enable the user to develop a loss factor for a given floating-roof device. This standard presents procedures for the evaluations to be performed under such a program, including preparation for protocol testing of individual devices, monitoring of the tests, and analysis and reporting of test results for the purposes of establishing evaporative loss factors.
It is not the purpose of this loss factor development program as given in the MPMS Ch. 19.3 series of standards to specify procedures to be used in the design, manufacture, or field installation of floating-roof devices. Furthermore, equipment cannot necessarily be selected for use solely on the basis of evaporative-loss considerations. Many other factors-such as tank operation, maintenance, and safety-are important in designing and selecting tank equipment for a given application.
This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
