Feature and Usage:
1. 3240: Applied for mechanical\electrical\electronic Equipment; Higher mechanical strength in medium temperature, and steadier electric features in moisture surrounding.

2. YS901, EPGC201: Applied for mechanical\electrical\electronic Equipment; Equals G-10 in NEMA Standard; Better mechanical strength in medium temperature, and steadier electric feature in high temperature.

3. YS902, EPGC202: Applied for mechanical\electrical\electronic Equipment; Equals to FR-4 in NEMA Standard; high mechanical feature in common temperature, better electrical feature in dry and wet state and better anti-fire feature.

4. YS903, EPGC203: Applied for mechanical\electrical\electronic Equipment as insulation fittings; still higher mechanical strength, better electric feature in dry and wet state.

5. YS904, EPGC204: Applied for mechanical\electrical\electronic Equipment as insulation fittings; still higher mechanical strength, better electric feature in dry and wet state, and better anti-fire feature.

Note:
1. GB/T: Standards of PRC.
IEC: Standards of International Electrical Commission
NEMA: Standards of National Electrical Manufactures Association
Q/YSB: Standards of Hebei Asian Sage Industry Co., Ltd.
YS901, YS902, YS903, YS904: type of the products

2. The product standard of this edition of Epoxy Glass Fiber Laminated Board and Phenolic Cotton Board is made according to the standard of GB/T, IEC, NEMA. Both types of products can be manufactured by the present equipment of Hebei Asian Sage Industry Co., Ltd..
