BS 7668:2016规定了可焊接材料的技术交付要求 耐候热加工无缝、电焊和埋弧 圆形焊接（纵向或螺旋）钢结构空心型材， 正方形、长方形或椭圆形。它适用于热成型的空心型材 进行或不进行后续热处理，或通过后续热处理冷成型 进行全身热处理，以获得与上述材料相同的冶金条件 在热成型产品中获得。该产品同样适用于焊接、螺栓连接和铆接结构。 这个 本英国标准中规定的空心型材用于 用于建筑或一般工程目的。公差要求， BS EN 10210-2规定了尺寸和截面特性。注:本标准规定了四种材料等级，用户应选择 与预期用途和使用条件相适应的等级。本英国标准不适用于， BS EN 10210-1、BS EN 10219-1、BS EN 10219-2或BS EN 10225。然而 BS 7668:2016中的等级与类似强度等级的等级兼容 BS EN 10025-5中规定。除明确要求外，本标准还要求 详细内容见第4条，并记录在案。为了符合本标准，双方 应满足最终要求和文件化项目。交叉引用:BS EN 287-1BS EN 1011-1BS EN 1011-2BS EN 10021BS EN 10027-1BS EN 10052BS EN 10079BS EN 10168BS EN 10204BS EN 10210-2BS EN ISO 148-1BS EN ISO 377BS EN ISO 2566-1BS EN ISO 6892-1BS EN ISO 10893-2BS EN ISO 10893-6BS EN ISO 10893-6BS EN ISO 10893-7BS EN ISO 10893-11BS EN ISO 15607BS EN ISO 15609- 1BS EN ISO 15614-1BS 6200BS EN 1993-1-10BS EN 10020BS EN 10025-5BS EN 10210-1BS EN ISO 9000购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS 7668:2016 specifies the technical delivery requirements for weldable weather resistant hot finished seamless, electric welded and submerged arc welded (longitudinal or helical) steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot with or without subsequent heat treatment, or formed cold with a subsequent full body heat treatment to obtain equivalent metallurgical conditions to those obtained in a hot formed product.The products are equally suitable for welded, bolted and riveted structures. The hollow sections specified in this British Standard are intended for use in construction or for general engineering purposes. Requirements for tolerances, dimensions and sectional properties are specified in BS EN 10210-2.NOTE Four material grades are specified in this standard and the user should select the grade appropriate to the intended use and service conditions.This British Standard does not apply to products currently covered by, BS EN 10210-1, BS EN 10219-1, BS EN 10219-2 or BS EN 10225. However, the grades in BS 7668:2016 are compatible with those of similar strength level specified in BS EN 10025-5.In addition to the definitive requirements, this standard also requires the items detailed in Clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items are to be satisfied.Cross References:BS EN 287-1BS EN 1011-1BS EN 1011-2BS EN 10021BS EN 10027-1BS EN 10052BS EN 10079BS EN 10168BS EN 10204BS EN 10210-2BS EN ISO 148-1BS EN ISO 377BS EN ISO 2566-1BS EN ISO 6892-1BS EN ISO 10893-2BS EN ISO 10893-3BS EN ISO 10893-6BS EN ISO 10893-7BS EN ISO 10893-11BS EN ISO 15607BS EN ISO 15609-1BS EN ISO 15614-1BS 6200BS EN 1993-1-10BS EN 10020BS EN 10025-5BS EN 10210-1BS EN ISO 9000All current amendments available at time of purchase are included with the purchase of this document.
