This section GB/T 1303 Part 3.

The partial modification of the use of IEC 60893-3-1:2003 "thermosetting resins for electrical industrial rigid laminated sheets - Part 3. Specifications for individual materials Regulation Fan Section 1. industrial rigid laminated plate model requirements "(2nd edition, in English).

This part of IEC 60893-3-1:2003 compared to the main differences are.

--- On the Format delete its "reference";

--- Added a technically Bismaleamic (BMI), polyamide imide (PAI), the abbreviation poly ether (DPO) and the corresponding resin Laminates Use and characteristics;

--- Delete provisions in Table 1 and the middle platen about the coarse and fine cloth textile reinforcement specifications comment.
