GB/T 1690-2010 Translated English of Chinese Standard (GBT 1690-2010, GB/T1690-2010, GBT1690-2010): Rubber, vulcanized or thermoplastic - Determination of the effect of liquidshttps://www.chinesestandard.net, 27 mai 2017 - 28 pages This standard specifies the methods of evaluating the resistance of vulcanized and thermoplastic rubbers to the action of liquids by measurement of properties of the rubbers before and after immersion in test liquids. The liquids concerned include current service liquids, such as petroleum derivatives, organic solvents, and chemical reagents, etc. This standard applies to vulcanized rubber or thermoplastic rubber. |
