Foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents"
Drafting:
This document replaces GB/T 30757-2014 "Classification of basic dense shaped refractory products with residual carbon content of 7% to 50%" and
Compared with GB/T 30757-2014, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Added terms and definitions (see Chapter 3);
b) The classification basis, product types and brands, raw material characteristics, and the names and descriptions of the combination forms have been changed (see Chapter 4,:2014 Edition):
3:1~3:5);
c) The description of nomenclature has been changed (see Chapter 5, Chapter 4 of the:2014 edition):
This document is modified to adopt ISO 10081-3:2003 "Classification of dense shaped refractory products Part 3: Alkali-based refractory products with a carbon content of 7% to 50%
Sexual Products:
This document has the following structural adjustments compared to ISO 10081-3:2003:
--- Added Chapter 3 "Terms and Definitions";
---4:2 corresponds to 3:2 and 3:3 in ISO 10081-3:2003:
The technical differences between this document and ISO 10081-3:2003 and their reasons are as follows:
--- Added normative reference document GB/T 18930 (see Chapter 3) to facilitate the search and use of terms;
---4:1a) corresponds to 3:1a) and 3:1b) in ISO 10081-3:2003: The classification basis is changed to four types, and the type and brand are merged to make the content
The connection is more coherent;
--- In 4:2, select the applicable national standard to replace the international standard, GB/T 17732 to replace ISO 10060, GB/T 21114 to replace
ISO 12677 and GB/T 34332 replace ISO 10058, and add the applicable GB/T 16555 test method:
The following editorial changes were made to this document:
--- In order to coordinate with the existing standards, the name of the standard is changed to "Classification of basic dense shaped refractory products with a carbon content of 7% to 50%";
--- Deleted Note 1 in ISO 10081-3:2003 “Scope”:
