Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 3857-2005 "glass fiber reinforced thermosetting plastics chemical resistance test method", and
GB/T 3857-2005 compared to the main technical changes are as follows.
--- expand the scope, increase the "other fiber or particle reinforced thermosetting plastic chemical resistance of the performance test, also refer to the use of"
(See Chapter 1, Chapter 1 of the.2005 edition);
- modified the expression of the principle (see Chapter 3, Chapter 3 of the.2005 edition);
- modified the size of the specimen (see 4.2, 4.2 of.2005);
- "trial age" is changed to "trial period and sampling time" (see 6.3, 6.3 of.2005);
- modified the sensitivity of the analytical balance (see 5.5,.2005 5.5);
- The provisions of the "Fiber Reinforced Standard Laminate Preparation Method" have been removed (see Appendix B of the.2005 edition).
This standard is proposed by the China Building Materials Federation.
This standard is under the jurisdiction of the National Technical Committee for Fiber Reinforced Plastics (SAC/TC39).
The drafting of this standard. East China University of Science and Technology, East China University of Science and Technology Huachang Polymer Co., Ltd., Shanghai Institute of Corrosion Science and Technology.
