Foreword

The Standard is a modified MIL-I-24768-13.1992 "Electrical insulation phenolic cotton board (FBE)", MIL-I-24768-14.1992 "Electric Workers with phenolic cotton insulation board (FBG) ", MIL-I-24768-15.1992" Electrical insulation phenolic cotton board (FBI) "and MIL-I-24768- 16.1992 "Electrical insulation phenolic cotton board (FBM)". This standard MIL-I-24768-13 and 24768-16 ~. The main technical difference in 1992 is as follows. 1) "bending strength" required value by MIL-I-24768 in a thickness of 0.5in and 0.75in required value; 2) "Impact strength parallel to the layer" simply supported beam method and the corresponding value of the test method requirements, units are in kJ/m2; 3) increase of the D-24/23 D-48/50, E-48/50 and other process conditions described; 4) The ASTM Test Method MIL-I-24768 standard referenced standards into the corresponding GB/T 1303.2-2009. The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized. This standard was drafted. Beijing Fu Runda new insulation material limited liability company, Guilin Institute of Electrical Science. The main drafters of this standard.
