GB/T 11793-2008Test methods on mechanical and weathering properties for unplasticized polyvinyl chloride (PVC-U) doors and windows (English PDF)

Foreword

This standard replaces GB/T 11793.1-1989 "PVC plastic window building physical performances", GB/T 11793.2-1989 "PVC plastic windows mechanical properties, weather resistance and technical conditions", GB/T 11793.3-1989 "plastic windows mechanical properties, weather resistance test methods." This standard and GB/T 11793.1-1989, GB/T 11793.2-1989, GB 11793.3-1989 main differences are as follows:

--- Remove the GB T 11793.1-1989, GB/T content/11793.2-1989, preserving the GB/T 11793.3-1989 of main content;

--- Increased requirements for mechanical properties test project sequence;

--- Increasing the relevant test methods for unplasticized polyvinyl chloride (PVC-U) plastic door;

--- Increasing the locking device (handle) switching force test;

--- Switch fatigue tests modified to repeated opening and closing performance test;

--- Modify the results of experiment and calculation method of the mechanical properties of welded angle destructive;

--- Artificial aging test by the aging time of 1000h modify the sample received cumulative radiation energy M class 8GJ/m2, S class 12GJ/m2; modify test after aging double V Charpy impact strength and color change spectrophotometer assay;

--- Natural weathering test is modified by exposure to two years to receive a sample accumulated in the UV wavelength range between 300nm ~ 800nm Radiant energy of light and visible light. M class 8GJ/m2, S class 12GJ/m2; aging test after adjustment for the double V simply supported beam Impact strength and color changes in a spectrophotometer assay;

--- Added Appendix A "calculated radiation intensity artificial aging tests and exposure time measurement", B "China's major gas Appendix Designate the type. " The Standard Appendix A, Appendix B is an informative annex. The standard proposed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China. This standard is under the jurisdiction of Housing and Urban products and components and parts of products Standardization Technical Committee of Ministry of Construction. This standard drafting unit. China Academy of Building Research. Participated in the drafting of this standard. Vicat Plastics (Shanghai) Co., Ltd., the National Chemical Building Materials Testing Center (Construction test unit). The main drafters of this standard. Huangjia Wen, Chen Qi, Jin Qian, Li Xin, Li Cong laugh. This standard replaces the standards previously issued as follows:

--- GB/T 11793.1-1989;

--- GB/T 11793.2-1989;

--- GB/T 11793.3-1989. Unplasticized polyvinyl chloride (P Vp CU) plastic doors and windows Mechanical properties and weathering test method

1 Scope

GB/T 11793-2008 is the Chinese national standard on test methods on mechanical and weathering properties for unplasticized polyvinyl chloride (pvc-u) doors and windows, in the field of construction materials and building. 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 24 December 2008 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 October 2009. Classification: ICS 91.060.50, CCS Q74. 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 unplasticized polyvinyl chloride (PVC-U) plastic doors and windows (hereinafter referred to as the plastic doors and windows) mechanical properties and weatherability term And definitions, test methods and test reports. This standard applies to unplasticized polyvinyl chloride (PVC-U) profiles produced by the mechanical properties of building doors and windows and weather resistance testing.
