摘要
对非表面处理类铝合金建筑型材国家标准中主要技术指标的确定作了说明。并介绍了新标准与GB/T5237-93标准中尺寸偏差、力学性能、表面质量相比较技术内容的变化。
The artical gives instruction of how technical requirements are determined,which are specified in the standard“wrought aluminium alloy extruded profiles for architecture—part I,Vntreated profiles”,and the differences of tolerances on dimensions,mechanical properties,surface quality of that between the new and last issue.
