Page 3 of 16 Foreword GB/T 1499 “Steel for the reinforcement of concrete” is divided into three parts: - Part 1: Hot rolled plain bars; - Part 2: Hot rolled ribbed bars; - Part 3: Welded fabric. This Part is Part 1 of GB/T 1499. This Part is drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces GB/T 1499.1-2008 “Steel for the Reinforcement of Concrete - Part 1: Hot Rolled Plain Bars”. As compared with GB/T 1499.1-2008, the main changes are as follows: - ADD some normative references; - DELETE HPB235 designation and its related technical requirements; - ADJUST the upper limit of S element content to 0.045%, and DELETE the related technical requirements for residual elements in steel; - DELETE 6.5 mm specification product and its related technical requirements; - ADD the requirement for bending per meter of straight bars; - TIGHTEN weight deviation; - ADD the measurement provisions when yield strength is not evident; - ADD the provision that re-inspection is not permitted when weight deviation is unacceptable; - ADD the provision that protruding factory name and other surface markings can be added on the surface of bars; - DELETE Appendix A (normative appendix) “Method for determination of total elongation of bars under the maximum force”. This Part uses the redraft law to refer to ISO 6935-1:2007 “Steel for the reinforcement of concrete - Part 1: Plain bars” for development. The degree of consistency with ISO 6935-1:2007 is not equivalent. www.ChineseStandard.net --> Buy True-PDF --> Auto-delivered in 0~10 minutes.
