This standard replaces GB/T 13939-1992 "vulcanized rubber thermal aging test method for tubular instrument law", and GB/T 13939-1992 Compared to the main technical changes are as follows. --- Remove the oxygen pressure vessel size requirements (see 1992 edition 4.2); --- Added "if the sample after aging tensile properties need to be tested, its thickness and width should be measured before the aging test" requirement (see 7.1). The use of standard reference ASTMD572-10 redrafted law "rubber thermal aging test method" preparation, and ASTMD572-10 The non-equivalent. 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. This standard replaces the standards previously issued as follows. --- GB/T 13939-1992. Vulcanized rubber thermal aging test method Tubular instrument law 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 ScopeThis standard specifies the test method for accelerated aging of vulcanized rubber at high temperature and high pressure oxygen environment. This standard applies to vulcanized rubber in the hot oxygen aging test factors.2 Normative referencesThe 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 531.1 vulcanized rubber or thermoplastic rubber hardness test pushed Part 1. Shore hardness method (Shore hardness) GB/T 2941 rubber physical test method for preparing and conditioning General Procedure3 Test principleRubber and its products to withstand prolonged heat and oxygen aging will inevitably lead to physical performance degradation. The sample is exposed to high temperature and high pressure oxygen ring Measure its properties throughout the aging after a certain time, and the performance of the unaged samples were compared.4 test device4.1 meter from the oxygen-type pressure vessels, heat transfer medium and climate control systems and other components. 4.2 oxygen tubular container is a pressure vessel made of metal, it should be maintained and the temperature of the pressurized environment. Place the container shall be provided with a sample Hanger, the size of the container should be able to ensure that the vertical sample suspended without contact with each other, do not touch the vessel wall. The best total volume of the sample does not exceed the capacity of 10% of the volume of the contents. Oxygen pressure vessel shall be equipped with a reliable safety valve to ensure that the pressure vessel pressure is less than 3.45MPa. Copper or copper parts can not be exposed to the test environment, pressure vessels, pipe fittings or valves not prepared copper material. 4.3 heat transfer medium optional water, air or other fluid under aerobic secure environment can be used as a heat transfer medium. Oil or combustible liquids shall not Used as a heat transfer medium. 4.4 thermostatic control system consists of a heating device, temperature controller and over-temperature protection device components. Climate control system can provide power protection and super Temperature insulation to prevent temperature increases resulting in accidents. Heat source can be optional, but should be placed outside the oxygen pressure vessel.5 Sample5.1 Sample parking, preparation and regulation should be consistent with the relevant provisions of GB/T 2941 in. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13939-2014_English be delivered?Answer: Upon your order, we will start to translate GB/T 13939-2014_English as soon as possible, and keep you informed of the progress.
