Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 25852-2010 "8 grade chain forging lifting parts". Compared with GB/T 25852-2010, the main technical
The technical changes are as follows.
--- modified the scope of application (see Chapter 1,.2010 edition of Chapter 1);
- modified normative references (see Chapter 2,.2010, Chapter 2);
- Amendments to terms such as deletion of work load, validation force, hanging chain, main ring, intermediate main ring, intermediate ring and lower end
(See Chapter 3, Chapter 3 of the.2010 edition);
- modified materials, heat treatment, manufacturing processes, mechanical properties and tests (see Chapters 4 and 5,
Chapter Chapter 9);
--- modified the contents of the logo (see Chapter 6,.2010 edition of Chapter 11);
--- modified the contents of the manufacturer's product certification (see Chapter 7,.2010 edition of Chapter 10);
--- Added the contents of the instruction manual (see Chapter 8);
- Removes the dimensions of the main ring, the middle main ring and the lower end ring of the forged lifting parts (see.2010 edition 4.1 and 4.2).
This standard uses the translation method equivalent to ISO 8539..2009 "8 grade chain steel forging lifting parts" (English version).
And the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows.
