Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 15255-1994 "vulcanized rubber artificial weathering (carbon arc lamp) test method", and GB/T 15255- The main technical changes compared to 1994 are as follows. --- Normative references revised. Removed GB/T 7762, which was added to the reference; deleted GB 9865; deleted GB/T 11189.2 and GB/T 12831; --- Increasing the drum rotates, the drum and the drum samples in the form of fixed description (see 4.1); --- Increased carbon arc lamp list of device types and operating conditions list (see 4.2.2 and 5.1); --- Increased cleaning filter description (see 4.3); --- The GB/T 12831 in the sample holder and blackboard thermometer provisions added to this standard (see 4.4, 4.5); --- Increased humidity controlled device and a sprinkler system, and adjust the position of the water quality requirements (see 46, 47, 1994 Version 5.4.); --- The GB/T 12831 in the provisions regarding determination of changes in the appearance of the sample was added to this standard (see 6.4); --- Will be adjusted to the corresponding section of the suspension bar (see 73, 1994. Version 7.3.); --- Increased by reference. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee rubber and rubber products, Common test methods for Club (SAC/TC35/SC2) centralized. This standard was drafted. Guangzhou Institute of Materials Co., Ltd., Beijing Rubber Industry Research and Design Institute. The main drafters of this standard. Xie Yufang, Yi Jun, Xie Junfang, Zhang Shudong. This standard replaces the standards previously issued as follows. --- GB/T 15255-1994. Vulcanized rubber artificial climate aging test Carbon arc lamp Warning. Use of this standard shall have a person experiences regular laboratory work. This standard does not point out all possible security issues. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.

1 Scope

This standard specifies the carbon arc lamp as the light source analog and strengthen the natural climate of light, heat, air, temperature, humidity and rainfall mainly due to An artificial climate aging hormone test methods. This standard applies to the assessment of weather-resistant vulcanized rubber in a carbon arc lamp as the light source of the test conditions.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 528 Determination of vulcanized rubber or thermoplastic rubber tensile stress-strain properties GB/T 2941 rubber physical test method for preparing and conditioning General Procedure GB/T 3511 vulcanized rubber or thermoplastic rubber weather resistance

3 Test principle

Vulcanized rubber is placed in a carbon arc lamp light source to simulate natural climate and strengthen the aging factors in the environment, the measurement sample before and after aging Changes in performance to evaluate weather resistance of the vulcanized rubber.

4 test device

4.1 Test Chamber Center chamber installed a carbon arc lamp, placed the box on a sample holder of the drum, the drum is rotated around the light source. Electric carbon arc provided on the housing Flow, carbon arc voltage, timers, and wet and dry bulb temperature indicating devices, control cabinets have a circulating air conditioner, used to adjust the temperature of the blackboard And discharge of tank ozone. Plate specimens can be placed directly on a drum or placed with a fixed sample test stand, shaped to form a vertical or inclined form. Case should be able to be prepared within the operating range of cycle exposure control means the conditions of the program. 4.2 a carbon arc lamp 4.2.1 open carbon arc lamp Two carbon rod electrodes open carbon arc lamp comprises a surface of copper, carbon arc formed between the electrodes can be automatically adjusted. Carbon arc irradiation through a plate glass filter to the surface of the sample 300nm ~ 750nm wavelength of light irradiance can not be greater than 600W/m2, Less than 300nm wavelength of light irradiance can not exceed 2W/m2.
