前言本出版物为加拿大标准协会编制，包含S136-94《冷成型钢结构构件》中引用的ASTM标准。它将与CSA标准S136-94一起用作参考工具。编制ASTM标准的目的是帮助CSA标准的用户，而不是取代S136-94，S136-94仍然是加拿大冷弯型钢结构构件设计的唯一源代码特定标准。虽然CSA引用了本书中包含的ASTM标准，但这些标准可能不是ASTM发布的最新版本。ASTM已将ASTM标准的目的和用途定义为:。涉及其条款的各方，即生产者、用户、消费者和一般利益集团的共同观点。它旨在帮助工业、政府机构和公众。 使用ASTM标准纯粹是自愿的。人们认识到，对于某些工作或某些地区，ASTM标准规范可能比需要的限制更多或更少。ASTM标准的存在并不妨碍任何人制造、营销或购买产品，或使用不符合该标准的产品、工艺或程序。由于ASTM标准需要定期审查和修订，因此使用这些标准的人应注意获取最新版本。“CSA是加拿大最大的检测和认证机构。作为一个非营利组织，它75年来一直在召集行业、政府和消费者的代表，共同制定安全和性能标准。所有与购买CSA标准有关的查询应发送至:加拿大标准协会，标准销售部，安大略省雷克斯代尔雷克斯代尔大道178号M9W 1R3； 电话:（416）747-4044；传真:（416）747-2475；或者联系最近的CSA办公室。

PrefaceThis publication was assembled for the Canadian Standards Association and contains those ASTM standards referenced in S136-94, Cold Formed Steel Structural Members. It is intended to be used as a reference tool in conjunction with CSA Standard S136-94.The purpose of compiling the ASTM standards is to aid users of the CSA standard and not to replace S136-94, which remains the only source-specific standard on the design of cold-formed steel structural members in Canada. While the issues of the ASTM standards contained in this book are referenced by CSA, these may not be the latest editions as published by ASTM.ASTM has defined the purpose and use of ASTM standards as representing:"".a common viewpoint of those parties concerned with its provisions, namely, producers, users, consumers, and general interest groups. It is intended to aid industry, government agencies, and the general public. The use of an ASTM standard is purely voluntary. It is recognized that, for certain work or in certain regions, ASTM standard specifications may be either more or less restrictive than needed. The existence of an ASTM standard does not preclude anyone from manufacturing, marketing, or purchasing products, or using products, processes, or procedures not conforming to the standard. Because ASTM standards are subject to periodic review and revision, those who use them are cautioned to obtain the latest revision.""CSA is Canada's largest and oldest standards-writing, certification, testing, and inspection organization. A not-for- profit association, it has been bringing representatives of industry, government, and consumers together for over 75 years to develop standards for safety and performance.All inquiries relating to the purchase of CSA standards should be addressed to: Canadian Standards Association, Standards Sales, 178 Rexdale Boulevard, Rexdale, Ontario M9W 1R3; Tel: (416)747-4044; FAX: (416)747-2475; or contact the nearest CSA office.
