15、titutece-IHS Emokes/1111111001.User-Wing.BemioNo roproduction or notworking permitled without liconso from IHSNot ler107 MDTFOREWORDThis standard provides rules for testing the deck fittings of external floating roofs underlaboratory conditions to provide evaporative loss information.It was prepared
16、 by TaskGroup II of the API Environmental Technical Advisory Group(ETAG).Testing programs conducted by API in 1984 and 1993 provided the information on whichthe current evaporative loss factors are based for common,generic types of external floating-roof deck fittings.These factors are published in
17、the API Manual of Petroleum MeasurementStandards,Chapter 19.2,for use in estimating the evaporative loss of petroleum stocks fromfloating-roof tanks.These factors and the test methods used to develop them have beenwidely accepted by oil companies,manufacturers,industry groups,regulatory agencies,and
18、general interest groups.API has not,however,tested or developed evaporative loss factorsfor proprietary designs of individual manufacturers.By publishing a testing protocol,API ismaking the test method available to interested parties who wish to test particular deck fittingsunder the auspices of API
19、.API certification of an evaporative loss factor developed through this program is subject tothe following three-step process:a.The testing shall be performed in laboratories licensed by API.The requirements to qual-ify for licensure are presented in the API Manual of Petroleum Measurement Standards
20、(MPMS),Chapter 19.3,Part G.b.Testing and determination of test results shall be performed as specified herein.c.The evaluation of these test results and the certification of an evaporative loss factor forthe item tested shall then be conducted in accordance with the API MPMS,Chapter 19.3,Part F.API
21、publications may be used by anyone desiring to do so.Every effort has been made bythe Institute to assure the accuracy and reliability of the data contained in them:however,theInstitute makes no representation,warranty,or guarantee in connection with this publicationand hereby expressly disclaims an
