---First released in:1996 as GB/T 16457-1996 "Superhard Material Saw Blade Base Dimensions";

---The first revision in:2009 was published in parts as GB/T 16457:1-2009 "Superhard Material Saw Blade Base Dimensions Part 1" Points: Mechanical cutting of building and civil engineering materials" and GB/T 16457:2-2009 "Superhard material saw blade base ruler Part 2: Hand-held cutting of building and civil engineering materials;

---This is the second revision and has been re-published in parts: This document corresponds to Part 2:

Due to different manufacturing processes, diamond circular saw blades are currently divided into two categories: welded saw blades and sintered saw blades: These two types of products are very Technical requirements vary widely: In order to scientifically and reasonably standardize the technical content of the diamond circular saw blade matrix, and in conjunction with GB/T 11270:1 "Diamond circular saw blades made of superhard abrasives - Part 1: Welded saw blades" and GB/T 11270:2 "Diamond circular saw blades made of superhard abrasives" "High-quality diamond circular saw blades - Part 2: Sintered saw blades" are harmonized, and GB/T 16457 "Diamond circular saw blade substrate" is planned to consist of the following two parts constitute:

---Part 1: For welding saw blades: The purpose is to establish technical specifications for the substrate used in welding process diamond circular saw blades:

---Part 2: For sintered saw blades: The purpose is to establish the technical specifications for the matrix used in sintering process diamond circular saw blades: Diamond circular saw blade base Part 2: For sintered saw blades

1 Scope

GB/T 16457.2-2023 is the Chinese national standard on blanks of diamond circular saw blade - part 2: for sintered saw blades, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 27 November 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2024. Classification: ICS 25.100.70, CCS J43. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document stipulates the code and marking, technical requirements, test methods, inspection rules and markings, packages for sintered diamond circular saw blades Loading, transportation and storage: This document applies to the matrix for sintered diamond circular saw blades:
