1 Scope

GB/T 12703.6-2010 is the Chinese national standard on textile - evaluation for electrostatic properties - part 6: fibre resistance leak, in the field of textile and leather technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 January 2011 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 August 2011. Classification: ICS 59.080.01, CCS W04. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

GB/T 12703 provisions of this part of the test method for all types of short fiber leakage resistance. This section applies to the determination of the leakage resistance of various types of short fibers.

2 Terms and definitions

The following terms and definitions apply

GB/T 12703 in this section.

2.1 Fiber leakage resistance fibreresistanceleak Characterization of fibers from an indicator of electrostatic nature. It is a different capacity capacitor C fibers and fiber surface resistivity of anti-adhesion Oil and other comprehensive electrostatic discharge resistance R of the time t, multiplying the resistance of the resistive index fiber 10n after the value represented by t × 10n (Omega) Fig. Principle

3 The use of resistive and capacitive discharge principle with different fiber resistance R connected across the charge to charge a fixed capacitance (C) ends its discharge rate to measure The resistance value of the amount of fiber.
