This section GB/T 4127 Part 17.

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

This section uses the redrafted law revision adopted ISO 603-17.2014 "fixed abrasive size Part 17. Sharpened head."

This part of ISO 603-17.2014 technical differences and the reasons are as follows.

--- On normative references, this standard made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation

Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows.

* Replacing ISO 525 with International Standard GB/T 2484;

* increase the reference GB/T 2485.

--- Modify the part of the size of the code (Sd to S, L3 to L1, L2 to L), in line with China's relevant national standards

Regulations

--- Modify the shape of each type handle grinding head and delete all the tables in the "mark" column, because the shape code and markings should be consistent with me

The relevant national standards of the country;

--- Removed all the tables in the "old code" column, as the first version of ISO 603-17.2014, there is no "old code" argument;

--- Table 1, Table 3, Table 4, Table 6 to Table 12 to add the size of the shank grinding head size, because the provisions of ISO 603-17.2014

Size series do not completely cover our product specifications;

--- Product marking, handle the material and signs and other technical requirements amended to comply with the relevant provisions of our national standards to meet our country

Usage and requirements.
