GB/T 29627.2-2013Aramid pressboard for electrical purposes -- Part 2: Methods of test (English PDF)

Foreword

GB/T 29627 "for electrical aromatic polyamide fiber carton" contains the following sections.

--- Part 1. Definitions, designations and general requirements;

--- Part 2. Test methods;

--- Part 3. Specifications for individual materials.

This section GB/T Part of 229,627.

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

This section uses redrafted law revision using IEC 61629-2:1996 "Electrical use aromatic polyamide fiber board - Part 2. Test side law".

This part of IEC 61629-2:1996 compared to the main technical differences are as follows.

--- Because of IEC 61629-2:1996 Zhi brief reference 60641-2 IEC . 1979 "Part 2 electrical crimp cardboard and thin cardboard no test method ", not as a related note, taking into account the aromatic polyamide fiber carton board and cellulose materials and uses. sub with, full reference to foreign advanced standards on the basis of this section has been rewritten;

--- The referenced IEC 60641-2:2004, representing an increase of flexural strength and flexural modulus frequency dielectric loss factor and relative permittivity Pollution properties, surface resistivity and low volume resistivity, dielectric liquid, Shore hardness, Izod impact strength, 1.2/50µs pulse OKI strength, temperature index (TI), and thermal conductivity detection method oxygen index, and so the appropriate test method criteria for inclusion Normative references to the chapter;

--- Remove the IEC 60641-2:2004 in the tear strength and edge tear strength, interlayer adhesion strength, pH and water extraction liquid metal Particle detection performance test method, the reason is not applicable to the above properties aramide fiber cardboard.

This part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized.
