Foreword
This document was drafted as per the rules specified in GB/T 1.1-2020 Directives for Standardization – Part 1: Rules for the Structure and Drafting of Standardizing Documents. This Document replaced GB/T 30314-2013 Rubber or Plastic-coated Fabrics - Determination of Abrasion Resistance - Taber Abrader. Compared with GB/T 30314-2013, the major technical changes of this Document are as follows:
--- Add non-flexible liner cardboard or its equivalent solid board for thin specimen fixation (see 4.9 of this Edition); correspondingly, add the relevant content in 4.1.3 (see 4.1.3 of this Edition);
--- Change the diameter of the specimen from 114mm into 105mm to 115mm; and also change the instruction 2 in Figure 1 accordingly (see Clause 5 of this Edition; Clause 5 of 2013 Edition);
--- Change the content of the preparation and installation of the specimen (see 7.1 of this Edition; 7.1 of 2013 Edition);
--- Change the content of the preparation of the grinding wheel surface (see 7.2.1 and 7.2.2 of this Edition; 7.2.1 and 7.2.2 of 2013 Edition).
This Document used translation method to equivalently adopt ISO 5470-1:2016 Rubber- or Plastics-Coated Fabrics – Determination of Abrasion Resistance – Part 1: Taber Abrader. The Chinese documents that have a consistent correspondence with the international documents normatively cited in this document are as follows:
