Foreword

This revised standard adopts ASTMD696. "Determination of plastic ---- 30 ℃ ~ 30 ℃ --- linear expansion coefficient of expansion of quartz 2003 Meter method. " This standard ASTMD696.2003 main differences are as follows. --- The "normative references" in the section referenced standards adopted national standards; --- Remove the ASTM standards "meaning and purpose" and "keywords" two chapters. This standard replaces GB/T 1036-1989 "plastic linear expansion coefficient of determination." This standard and GB/T 1036-1989 The main differences are as follows. --- Clear the scope of application, including the expansion meter, linear expansion coefficient range, temperature range; --- Increase the contraction of the sample approaches; --- Increase correction method; --- Increased precision. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee of plastic products and plastic resins General Methods Chapter (SAC/TC15/SC4) centralized. This standard is drafted by. Sinopec hospital north of the National Chemical Building Materials Testing Center (Materials Testing section). Participated in the drafting of this standard. National Quality Supervision and Inspection Center of synthetic resin, Beijing Yanshan Petrochemical resin, National Plastic Products Quality Center (Beijing), National Petrochemical organic synthetic resin raw material quality inspection center, Guangzhou Blonde Technology Co., Ltd. The main drafters of this standard. Hu Xiaoyi, Zhang Shanshan, Wang Zhenjiang, Wang Jiandong, Chen is willing, Li Jianjun, Wang Chao first. This standard replaces the standards previously issued as follows. --- GB/T 1036-1989. Determination of coefficient of linear expansion of plastic ℃ -30 ℃ ~ 30 Quartz dilatometer method

1 Scope

This standard specifies the use of quartz was measured by the method of expanded plastic in -30 ℃ ~ 30 ℃ linear expansion coefficient. This standard applies to the use of quartz dilatometer linear expansion coefficient of linear expansion coefficient greater than 1 × 10-6 ℃ -1 plastic material will be Determination. NOTE. In the test temperature or pressure, the plastic material occurs a negligible creep or elastic deformation (or both), will be within a certain range Affect test accuracy. This standard does not apply to material for the linear expansion coefficient is very low (less than 1 × 10-6 ℃ -1) of. For low expansion coefficient material is recommended Interferometer or capacitive technology.

3 Terms and Definitions

Terms and definitions GB/T 2035-2008 established apply to this standard. Principle 4 In this method, the measured length of the original specimen mount quartz dilatometer, dilatometer and then insert has a constant temperature bath at different temperatures Inside, the sample temperature and the constant temperature bath balance, measuring the change in length of the instrument indicated value is stable, the readings are recorded by the sample values \u200b\u200bof the expansion and contraction Value, you can calculate the coefficient of linear expansion of the sample. This standard specifies -30 ℃ ~ + 30 ℃ temperature measurement for the General, in accordance with product standard. If the temperature measured at the specified material Exists within the phase transition point, or glass transition point should be above and below the transition point were measured linear expansion coefficient, in order to avoid too Large measurement errors.

5 Instruments

Quartz dilatometer 5.1. 1, between the outer tube and the inner tube within the distance of about 1mm. 5.2 measuring the change in length of the instrument. it is fixed in the fixture so that it can change with the position of the installed length of the sample varies. need To a certain degree of accuracy to ensure that the error is within ± 1.0μm range. Plus the weight of the quartz tube measuring instrument reflect the weight of the total test Pressure exerted on the sample should not exceed 70kPa, to ensure that the sample is not twisted or contracted significantly. Caliper 5.3. initial length of the sample can be measured with an accuracy of ± 0.5%. 5.4 temperature controlled environment. providing a constant environment for the test sample, the temperature control at ± 0.2 ℃. NOTE. If you use a mobile liquid bath is better, should contact with the liquid bath and the test sample to avoid. If such exposure can not be avoided, be selected such that a liquid bath It does not affect the physical properties of the material. ......
