EN ISO 8986-2:2009 (E) DIN EN ISO 8986-2:2010-04 3 This document (EN ISO 8986-2:2009) has been prepared by Technical Committee ISO/TC 61 “Plastics” in 1 Scope This part of ISO 8986 specifies the methods of preparation of test specimens and the test methods to be used in determining the propert
25、ies of polybutene-1 (PB-1) moulding and extrusion materials. For the sake of simplicity, the designation polybutene and the abbreviation PB are used in both parts of ISO 8986. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before
26、 testing are also specified. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PB moulding and extrusion
27、materials are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of ISO 8986, as is the designatory property specified in Par
28、t 1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of di
29、fferent dimensions or prepared using different procedures. 2 Normative references The following referenced documents are indispensable for the application of this document.

It is essential that the specimens are always prepared by the same procedure using th
42、e same processing conditions. The material shall be kept in moisture-proof containers until it is required for use. The moisture content of filled or reinforced materials shall be expressed as a percentage of the total mass of the compound. 3.2 Treatment of the material before moulding Before proces
43、sing, no pretreatment of the material sample is normally necessary. 3.3 Compression moulding Compression-moulded sheets shall be prepared in accordance with ISO 293, using the conditions specified in Table 1.

The test specimens required for the determinati
45、on of the properties shall be machined from the compression-moulded sheets in accordance with ISO 2818 or punched out. A type 1 (frame) mould may be used, but it is necessary to start cooling whilst simultaneously applying the full pressure. This avoids the melt being pressed out of the frame and av
46、oids sink marks. For thicker sheet ( 4 mm), a type 2 (positive) mould has been found to work satisfactorily. The preheating time depends on the type of mould and the type of energy input (steam or electricity). For frame moulds, 5 min is usually sufficient but for positive moulds, due to the bigger
47、mass, a preheating time of up to 15 min may be necessary, especially if electric heating is used. NOTE 1 Since only the average cooling rate is specified, the actual cooling rate during crystallization is not fixed. This can lead to significant deviations in properties related to crystallinity, such
48、 as density and mechanical properties. NOTE 2 Since for frame moulds full pressure is only applied upon cooling, compression-moulded sheets may suffer from insufficient homogeneity and pellet boundaries may be preserved if the heating time or the pressure is insufficient.
