1、Designation: D 1201 99 (Reapproved 2004)Standard Specification forThermosetting Polyester Molding Compounds1This standard is issued under the fixed designation D 1201; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of las

2、t revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers compression molding, thermo-setting, unsaturated polyester molding compounds as furtherdefine

3、d in 3.1.1.2 The values stated in SI units are to be regarded as thestandard.NOTE 1The properties included in this specification are those re-quired to identify the types of molding compounds covered. There may beother requirements necessary to identify particular characteristics. Thesewill be added

4、 to the specification as their inclusion becomes generallydesirable and the necessary test data and methods become available.NOTE 2ISO 36721: 1979(E) is similar but not equivalent to thisspecification.

Number of Tests8.1 One set of test specimens as prescribed in Section 7shall be considered sufficient for testing each batch. Theaverage result for the specimens tested shall conform to therequir

19、ements prescribed in this specification. All of the testslisted in Section 7 shall be used to establish conformity of amaterial to this specification. It is recommended that routineinspection be limited to those tests required to identify thematerial to the satisfaction of the purchaser. The purchas

20、ershall state in the contract or order the tests which themanufacturer will be required to make on each shipment foridentification of the material.9. Rejection and Rehearing9.1 Compounds that fail to conform to the requirements ofthis specification may be rejected. Rejection should be reportedto the
