Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document supersedes GB/T 26941.1-2011 "Isolation Fences - Part 1: General Rules" and GB/T 26941.2-2011 "Isolation Fences - Part 1: General Rules".

Part 2: Posts, Braces and Gates; GB/T 26941.3-2011 "Guarding Fence Part 3: Welded Wire Mesh"; GB/T 26941.4-2011 "Guarding Fence Part 2: Posts, Braces and Gates"...2.Posts, GB/T 26941.5-2011 "Fence Part 4: Barbed Wire Mesh", GB/T 26941.6-GB/T 26941.1-2011 "Guarding Fence - Part 6: Expanded Metal Mesh". This document is based on GB/T 26941.1-2011 and integrates GB/T 26941.2~ GB/T 26941.6-2011.Compared with GB/T 26941.1-2011, the main technical changes, apart from structural adjustments and editorial modifications, are as follows.

a) Added terms and definitions for fencing and barbed wire (see 3.1 and 3.2);

b) The composition of the isolation fence has been changed (see 4.1, 3.1 in the 2011 version);

c) The content of the categories has been changed (see 4.2, 3.2 in the 2011 version);

d) Added designation requirements for various types of fencing (see 4.3);

e) The "General Requirements" were changed to "Appearance Quality," and its requirements were revised (see 5.1, 4.1 of the 2011 edition);

f) Increased requirements for structural dimensions, precision, materials, and processing (see 5.2~5.4);

g) The technical requirements and test methods for the quality of the anti-corrosion coating have been revised (see 5.5, 6.4, and 4.2 and 5.4.2 in the 2011 edition);

h) The requirements for experimental environment conditions, reagents, experimental instruments and equipment have been deleted (see 5.1~5.3 of the 2011 edition);

i) Test methods for structural dimensions and mechanical properties have been added (see 6.2 and 6.3);

j) The inspection rules have been changed (see Chapter 7, Chapter 6 in the 2011 edition);

k) Changes have been made to the requirements for marking, packaging, transport, and storage (see Chapter 8, 7.1–7.4 of the 2011 edition);

l) The requirement for accompanying documents has been removed (see 7.5 in the 2011 version).
