Summary This standard specifies the general rules and procedures hot pressed molded thermoset material sample preparation. This standard specifies the details of the performance test report shall contain the relevant sample preparation. This standard gives general design principles for preparing samples with mold. In order to reproduce the method of sample preparation, the test results discussed in this standard basic conditions with a comparable sample preparation involved. This standard applies to phenolic resin, amino resin, melamine/phenolic, epoxy and unsaturated polyester resin-based material thermoset powder molding compounds (PMCs). Because some of the molding compound composition, liquidity or other variables, the sample preparation may be required according to a predetermined method. In this case the need for consent of the parties, and indicate in the molding report.

Foreword

This standard is identical with ISO 295.2004 "Plastics --- thermosetting plastic compression molded specimens" (in English). This standard is equivalent translation ISO 295.2004. For ease of use, this standard made the following editorial changes. --- "This International Standard" by "this standard"; "." --- With a decimal point instead of a comma as the decimal point, ""; --- Deleted the ISO foreword; --- For the ISO 295.2004 international standard references, there is adopted as the equivalent of a standard, instead of the international standard of reference Standard, the rest not tantamount to the adoption of the standards of China, are directly referenced in the standard. This standard replaces GB/T 5471-1985 "thermosetting molding compression molding sample preparation method." This standard and GB/T 5471-1985 compared to the major differences are as follows. --- Modify the standard name; --- Increasing the scope of a chapter; --- Increasing the normative references chapter. 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. National Quality Supervision and Inspection Center of synthetic resin. Participated in the drafting of this standard. Sichuan University, Beijing Yanshan Petrochemical resin, Sinopec hospital north of the National Chemical Building Materials Test Center. The main drafters of this standard.

1 Scope

The standards establish general rules and procedures to suppress hot molding to prepare specimens of thermosetting materials. This standard specifies the details of the performance test report shall contain the relevant sample preparation. This standard gives general design principles sample was prepared mold. In order to reproduce the method of specimen preparation, test results are discussed in this standard has a substantially comparable conditions of sample preparation involved. This standard applies to phenolic resin, amino resin, melamine/phenolic, epoxy and unsaturated polyester resin-based material is a thermosetting powder Molding compound (PMCs). Because some of the molding compound composition, liquidity or other variables may be required in accordance with the method of preparation of test kind. In this case it requires consent of the parties, and indicate in the molding report.
