28、006INTRODUCTION This International Standard is one of a series which deals with heat-shrinkable moulded shapes. The series consists of the following parts: Part 1: Definitions and general requirements (IEC 62329-1) Part 2: Methods of test (IEC 62329-2) Part 3: Specification requirements for shape di

29、mensions, material requirements and compatibility performance (IEC 62329-3) (in consideration) 7 EN 62329-2:2006HEAT-SHRINKABLE MOULDED SHAPES Part 2: Methods of test 1 Scope This part of IEC 62329 gives methods of test for heat-shrinkable moulded shapes in a range of configurations and materials su

30、itable for insulation, environmental sealing, mechanical protection and strain relief for connector/cable terminations and multi-way transitions. The tests specified are designed to control the quality of the moulded shapes but it is recognized that they do not completely establish the suitability o

31、f moulded shapes for impregnation or encapsulation processes or other specialized applications. Where necessary, the test methods in this Part will need to be supplemented by appropriate impregnation or compatibility tests to suit the individual circumstances. 2 Normative references The following re

41、t conditions Unless otherwise specified, all tests shall be made under standard ambient conditions according to IEC 60212; i.e. at a temperature between 15 C and 35 C and at ambient relative humidity. In cases of dispute, the tests shall be carried out at a temperature of 23 C 2 K and at (50 5) % re

42、lative humidity. When heating at elevated temperature is specified for a test procedure, the specimen shall be maintained for the prescribed period in a uniformly heated oven complying with either IEC 60216-4-1 or IEC 60216-4-2. Where a test at low temperature is specified, the specification sheets

43、of IEC 62329-3 may require it to be carried out at t C or lower, where t is the requested temperature. In such cases the operator may carry out the test at the specified temperature or any lower temperature which is convenient. If, however, at a temperature below that specified, the specimen fails t

44、o meet the requirements, the test shall be repeated at the specified temperature, subject to a tolerance of 3 K as specified in IEC 60212. If the specimen then passes, it shall be considered to have met the requirements. _ 1This standard has been withdrawn. 9 EN 62329-2:20064 Standard test specimens

45、 4.1 Moulded shape material specimens Moulded shape material specimens shall be prepared from (2 0,15) mm thick sheets, unless otherwise specified, and shall be prepared from the same heat-shrinkable material that is to be used to manufacture the heat-shrinkable moulded shapes. The dimensions of the

46、 sheet shall be sufficient to enable any of the relevant tests to be performed. NOTE A suitable size has been found to be 150 mm x 150 mm. 4.2 Moulded shape compatibility specimens See IEC 62329-1, Subclause 4.2, and Clause 31 of this standard. 5 Dimensions 5.1 Number of test specimens Three specime

47、ns of each size and style shall be tested. 5.2 Procedure Measure the moulded shapes in the as supplied condition and after unrestricted shrinkage as specified in IEC 62329-3. Carry out unrestricted shrinkage by conditioning in an oven for the time and temperature specified in IEC 62329-3. Remove the

48、 shapes from the oven and allow to cool naturally to the ambient temperature specified in Clause 3. The method of measurement can be mechanical, or optical. Wall thickness shall be measured to an accuracy of 0,05 mm and internal diameter to an accuracy of 0,25 mm. In the case of dispute an optical m

49、ethod shall be used. 5.3 Result Report all measured values as the result. 6 Density 6.1 Number of test specimens At least three specimens shall be tested, cut from a test sheet in accordance with 4.1. 6.2 Procedure Any method for the determination of the density may be used which can ensure an accuracy of 0,01 g/cm3. 6.3 Report Record the method selected for the determination and report all measured
