IS 13360 : Part 4 : Sec 3 : 2004 Plastics - Methods of Testing - Part 4 : Rhelogical Properties - Section 3 : Determination of Spiral Flow of Low-Pressure Thermosetting Mou

NATIONAL FOREWORD

1.1 This test method covers a procedure for measuring the spiral flow of thermosetting motdding compounds (soft or very soft) designed for mouldingpressures under 6.9 MPa. It is especially suited for those compounds that may be used for encapsulation or other low pressure moulding techniques. Textile-reinforced compounds should not be tested using this test method. It involves the use of a standard spiral flow mould in a transfer moulding press under specified conditions of applied temperature and pressure with a controlled charge mass.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the application of regulatory limitations prior to use.
