Preface: This standard equate the ISO62:2008 "plastics - determination of water imbibition" (English version). This standard equivalent translation ISO62:2008. Instead of this standard GB/T1034-1998 plastic water imbibition test method. This standard and the main differences of the GB/T1034-1998 : - increased the introduction; - the quality of the sample measurement accuracy from 1 to 0.1 MG MG (chapter 4); GB/T 1034-1998 Plastics--Determination of water absorption test method of combined into 2 and 4 of this standard method 3; The test temperature range at room temperature from 23.0 ℃ to 0.5 ℃ + 23.0 ℃ + / - 1.0 ℃ or 23.0 ℃ + / - 2.0 ℃, humidity from 50% to 50% + / - 5% or 50% plus or minus 10% (chapter 6); - increase in results have g (FICK diffusion law determination of saturated water absorption and diffusion coefficient (chapter 7). - increased Appendix A: water imbibition and gathered in the validation sample (FICK diffusion law of correlation; - increases the appendix B: ISO62:2008 appendix B of the precise descriptions; - increases the appendix C: this standard and GB/T1034-1998 samples of major differences. The appendix A of this international standard, the appendix B and appendix C for informative appendices. This standard put forward by China petroleum and chemical industry association. This standard by the national standardization technical committee (SAC/TC15) plastic under centralized. This standard is responsible for drafting unit: resin application research institute, sinopec Beijing yanshan branch of guangzhou synthetic materials research institute co., LTD. This standard To participate in the drafting unit: national quality supervision and inspection center of synthetic resin, the national chemical building materials test center (material testing), guangzhou blonde technology co., LTD. Main drafter of this standard: Ceng Wei lili, Wang Haojiang, Li Siyu, chun-mei Yang, rocky, stone into the autumn, Li Jun, Song Guirong, liu chang, tong-min CAI. This standard in 197 0 years first launched in October, December 1998 revision for the first time, this is the second amendment.  
Description:This standard stimulates the determination of flat or curved surface shape of solid plastic water imbibition method in the thickness direction.
also this standard when specimens immersed in water or under the condition of certain humidity, plastic water quantity of sample size measurement rules. Assumption of single-phase material with constant water imbibition are gathered through the specimen thickness direction diffusion behavior, so the moisture diffusion coefficient through the thickness direction can be determined. The model of homogeneous material and reinforced polymer binders in glass transition temperature The test is effective. Some two-phase makings, however, such as cured epoxy resin may be required to multiphase absorption model, is not included in the scope of this standard.
