GB/T 11115-2009Polyethylene(PE) resin (English PDF)

Foreword

This Standard replaces GB/T 11115-1989 Low density polyethylene resin, GB/T 11116-1989 High density polyethylene resin and GB/T 15182-1994 Linear low density polyethylene resin. Compared with GB/T 11115, GB/T 11116 and GB/T 15182, the main differences of this Standard are as follows: - Combined GB/T 11115, GB/T 11116 and GB/T 15182 into one standard; - In addition to hygienic standard, all normative references in Chapter 2 were changed as dated references; - Added Chapter

3 Classification and designation; - In 5.1, deleted the requirements of "the particle size shall be (25)mm in any direction" in

3.1 in the original standard; and changed "without mechanical impurity" into "without impurity". - Added "Sample preparation" in the table in Chapter

5 Requirements; - Replaced "cleanliness (colored particle)" with "granular appearance" in the table in Chapter

5 Requirements; - Added "because the application field of each resin is different, the injection molding sample proprieties can be different from that of compression molding sample" in 6.2.2. The specific prepare method of each resin is shown in Table 1 to Table 7; - Adjusted the blow molding process of LLDPE film and LDPE film; and deleted "reduced diameter of film" in 6.2.3; - Specified two test methods for "fish-eye" in 6.10; - Re-specified the test method for "strip" in 6.11; - Added provisions on the shelf life of polyethylene resin in Chapter 9. This Standard was proposed by China Petrochemical Corporation (Sinopec Group). This Standard shall be under the jurisdiction of Petrochemical Plastic Resins Product Branch of National Standardization Technical Committee of Plastic (SAC/TC 15/SC 1). Responsible drafting organization of this Standard.

1 Scope

GB/T 11115-2009 is the Chinese national standard on polyethylene(pe) resin, 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 17 July 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 February 2010. Classification: ICS 83.080.20, CCS G32. 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 specified the classification and designation, requirements, test methods, inspection rules, product labelling, packaging, transportation and storage for polyethylene (PE) resin. This Standard applies to ethylene homopolymer OR copolymer that takes ethylene and other 1-olefin as monomer AND polymer that contains additives. This Standard does not apply to ultra-high molecular weight polyethylene AND colored, filled, modified, enhanced polyethylene resin AND masterbatch pellets.
