Foreword

GB/T 7113 "insulation hose" is divided into the following sections.

--- Part 1. Definitions and general requirements;

--- Part 2. Test methods;

--- Part 3. PVC glass fiber braided hose;

--- Part 4. acrylic glass fiber braided hose;

--- Part 5. Silicone rubber fiberglass braided hose;

--- Part 6. Polyurethane (PUR) glass fiber braided hose;

This section GB/T 7113 Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 7113-2003 "insulation hose Definitions and general requirements", compared with the GB/T 7113-2003 major changes as follows.

--- Standard "range" is further described;

--- Increasing the "order", "qualification requirements", "correlation between size and/or color," "trust test" and other sections, delete the words "general Requirements "section (see Chapter 6, Section 12, Chapter 13 and Chapter 14, Chapter 5, 2003 edition).

This section uses redrafted law revision using IEC 60684-1:2003 "insulating sleeving - Part 1. Definitions and general requirements." this Part of IEC 60684-1:2003 compared to do the following editorial changes.

--- Remove the IEC 60684-1:2003's "Introduction", in the "Categories" section adds illustration;

--- To avoid suspension segment separately in the "classification", "Size" two chapters increased by 5.1 and 7.1 "General." this part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized.

This section is drafted. Hangzhou Xiaoshan Insulation Material Factory, Guilin Electric Apparatus Research Institute Limited.
