GB/T 23615.1-2017 in English

《GB/T 23615.1-2017铝合金建筑型材用隔热材料 第1部分：聚酰胺型材》由TC243（全国有色金属标准化技术委员会）归口，TC243SC1（全国有色金属标准化技术委员会轻金属分会）执行，主管部门为中国有色金属工业协会。

1 Scope

This part of GB/T 23615 specifies those requirements for polyamide profiles, including terms and definitions, requirements, test methods, inspection rules, marking, packaging, transportation, storage and quality certificate as well as content of order (or contract).

It is applicable to polyamide profiles, a kind of thermal barrier material for architecture aluminium alloy extruded profiles.

Other types extruded thermal barrier materials may also refer to the provisions of this part.

3 Terms and Definitions

For the purposes of this document, the terms and definitions given in GB/T 2035 and the following apply.

3.1

polyamide profiles

hot-extruded profiles taking polyamide 66 and glass fibre as major raw materials, used in aluminum alloy thermal barrier profiles to play the role of structural connection and reducing heat transfer effect

4 Requirements

4.1 Product classification

Polyamide profiles are divided into two types, i.e. Type I and non-Type I, according to section structure; see Figure 1 and Figure 2 for typical section examples.
