GB/T 15065-2009Black polyethylene compounds for wire and cable (English PDF)

Foreword

This standard replaces GB 15065-1994 "black polyethylene plastic wire and cable." This standard compared with GB 15065-1994 main changes are as follows:

--- Normative references are changed to date references, and references to the latest version;

--- Increase the reference standard GB/T 2951.12-2008, GB/T 2951.14-2008, GB/T 2951.41-2008, GB/T 2951.42-2008, GB/T 18251-2000;

3.2 MH (black medium density polyethylene jacket material), NMJ (black weathering medium density polyethylene insulation materials);

--- Table 2 adds NDH, LDH, GH hot air oven aging tensile strength and tensile strain requirements;

--- Factory inspection items increased "density";

--- Table 2 carbon black dispersion to <=3 level;

--- Table NDH, LDH, GH, NDJ, NLDJ, NGJ the density changes;

--- Table melt flow rate of GH quality 2 to 2.0g/10min;

--- Environmental stress cracking resistance test in TX-10 20% aqueous reagent to TX-10 reagent 10% aqueous solution;

--- OIT press GB/T 2951.42-2008 carried out;

--- Carbon black dispersion according to GB/T 18251-2000 carried out;

--- Hot air oven aging increases MH, test temperature of GH;

6.3 in Table 4 is changed;

1 Scope

GB/T 15065-2009 is the Chinese national standard on black polyethylene compounds for wire and cable, in the field of rubber and plastic industries. 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 15 October 2009 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 March 2010. Classification: ICS 83.080.20, CCS K15. 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.

This standard specifies the black wire and cable polyethylene plastic (hereinafter referred to as "polyethylene cable") product classifications, requirements, test side Method, inspection rules and signs, packaging, transportation and storage. This standard applies to polyethylene resin as the main raw material carbon black, antioxidants and other additives, mixing, plasticizing and granulating the resulting polyethylene Cable.
