API SPEC*6FD9507322900538637073STEPOne of the most significant long-term trends affecting the future vitality of the petroleumindustry is the publics concerns about the environment.Recognizing this trend,APImember companies have developed a positive,forward looking strategy called STEP:Strategies for Todays Environmental Partnership.This program aims to address publicconcerns by improving industrys environmental,health and safety performance;doc-umenting performance improvements;and communicating them to the public.Thefoundation of STEP is the API Environmental Mission and Guiding EnvironmentalPrinciples.API standards,by promoting the use of sound engineering and operationalpractices,are an important means of implementing APIs STEP program.API ENVIRONMENTAL MISSION AND GUIDINGENVIRONMENTAL PRINCIPLESThe members of the American Petroleum Institute are dedicated to continuous efforts toimprove the compatibility of our operations with the environment while economically de-veloping energy resources and supplying high quality products and services to consumers.The members recognize the importance of efficiently meeting societys needs and our re-sponsibility to work with the public,the government,and others to develop and to use nat-ural resources in an environmentally sound manner while protecting the health and safetyof our employees and the public.To meet these responsibilities,API members pledge tomanage our businesses according to these principles:To recognize and to respond to community concerns about our raw materials,prod-ucts and operations.To operate our plants and facilities,and to handle our raw materials and products in amanner that protects the environment,and the safety and health of our employees andthe public.To make safety,health and environmental considerations a priority in our planning,and our development of new products and processes.To advise promptly appropriate officials,employees,customers and the public of in-formation on significant industry-related safety,health and environmental hazards,andto recommend protective measures.To counsel customers,transporters and others in the safe use,transportation and dis-posal of our raw materials,products and waste materials.To economically develop and produce natural resources and to conserve those re-sources by using energy efficiently.To extend knowledge by conducting or supporting research on the safety,health andenvironmental effects of our raw materials,products,processes and waste materials.To commit to reduce overall emissions and waste generation.To work with others to resolve problems created by handling and disposal of haz-ardous substances from our operations.To participate with government and others in creating responsible laws,regulationsand standards to safeguard the community,workplace and environment.To promote these principles and practices by sharing experiences and offering assis-tance to others who produce,handle,use,transport or dispose of similar raw materials,petroleum products and wastes.Not for ResaleAPI SPEC*6FD9507322900538638T0TSpecification forFire Test for Check ValvesExploration and

SPEC*bFD9507322900538639946SPECIAL NOTESAPI publications necessarily address problems of a general nature.With respect to par-ticular circumstances,local,state,and federal laws and regulations should be reviewed.API is not undertaking to meet the duties of employers,manufacturers,or suppliers towarn and properly train and equip their employees,and others exposed,concerning healthand safety risks and precautions,nor undertaking their obligations under local,state,or fed-eral laws.Information concerning safety and health risks and proper precautions with respect toparticular materials and conditions should be obtained from the employer,the manufactureror supplier of that material,or the material safety data sheet.Nothing contained in any API publication is to be construed as granting any right,by im-plication or otherwise,for the manufacture,sale,or use of any method,apparatus,or prod-uct covered by letters patent.Neither should anything contained in the publication beconstrued as insuring anyone against liability for infringement of letters patent.Generally,API standards are reviewed and revised,reaffirmed,or withdrawn at least ev-ery five years.Sometimes a one-time extension of up to two years will be added to this re-view cycle.This publication will no longer be in effect five years after its publication dateas an operative API standard or,where an extension has been granted,upon republication.Status of the publication can be ascertained from the APl Authoring Department telephone(214)953-1101.A catalog of API publications and materials is published annually and up-dated quarterly by API,1220 L Street,N.W.,Washington,D.C.20005.This document was produced under API standardization procedures that ensure appro-priate notification and participation in the developmental process and is designated as anAPI standard.Questions concerning the interpretation of the content of this standard orcomments and questions concerning the procedures under which this standard was devel-oped should be directed in writing to the director of the Exploration and Production Depart-ment,American Petroleum Institute,700 North Pearl,Suite 1840,Dallas,Texas 75201.Requests for permission to reproduce or translate all or any part of the material publishedherein should also be addressed to the director.API publications may be used by anyone desiring to do so.Every effort has been madeby the Institute to assure the accuracy and reliability of the data contained in them;however,the Institute makes no representation,warranty,or guarantee in connection with this pub-lication and hereby expressly disclaims any liability or responsibility for loss or damage re-sulting from its use or for the violation of any federal,state,or municipal regulation withwhich this publication may conflict.API standards are published to facilitate the broad availability of proven,sound engi-neering and operating practices.These standards are not intended to obviate the need for ap-plying sound engineering judgment regarding when and where these standards should beutilized.The formulation and publication of API standards is not intended in any way to in-hibit anyone from using any other practices.Any manufacturer marking equipment or materials in conformance with the marking re-quirements of an API standard is solely responsible for complying with all the applicablerequirements of that standard.API does not represent,warrant,or guarantee that such prod-ucts do in fact conform to the applicable API standard.Copyright 1994 American Petroleum InstituteNo
