33 European foreword
34 This document (prEN 50342-5:2024) has been prepared by CLC/TC 21X, ”Secondary cells and batteries”.
35 This document is currently submitted to the Enquiry.
36 The following dates are proposed:
• latest date by which the existence of this (doa) dor + 6 months
document has to be announced at national
level
• latest date by which this document has to be (dop) dor + 12 months
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) dor + 36 months
conflicting with this document have to be (to be confirmed or
withdrawn modified when voting)
37 This document will supersede EN 50342-5:2010 and all of its amendments and corrigenda (if any).
38 1 Scope
39 This document is applicable to housing and accessory parts of lead-acid batteries made of polypropylene.
40 Lead-acid batteries are used primarily as a power source for the starting of internal combustion engines,
41 lighting and for auxiliary equipment of road vehicles. These batteries are all referred to as starter batteries.
42 This document is applicable to starter batteries for passenger cars and for commercial or industrial vehicles.
43 Battery housing and accessory parts according to this document do not provide any protection of the
44 polypropylene against aging due to light. The parts are intended to be used within the engine compartment or
45 within battery boxes where they are protected from light.
46 The purpose of this document is to define requirements for raw material used to produce housing and
47 accessory parts for starter batteries, to define requirements of the physical properties of battery housing and
48 to define uniform test procedures for validation.
49 2 Normative references
50 The following documents are referred to in the text in such a way that some or all of their content constitutes
51 requirements of this document. For dated references, only the edition cited applies. For undated references,
52 the latest edition of the referenced document (including any amendments) applies.

87 4 Properties of raw materials
88 4.1 General
89 The examination of the raw materials should be performed in accordance to the specifications shown in
90 Annex B. If not agreed otherwise, the results need to be documented in a corresponding material
91 specification.
92 Test methods are based on international ISO standards. The needed specimens for the individual examination
93 are given in Annex B.
94 The specimens shall be stored before starting any test for at least 4 days at (23° ± 0,5) °C and shall be tested
95 within 3 months.
96 Annex C recommends possible test procedures for the material properties taken out of the battery housing,
97 without being normative.
98 4.2 Resistance against chemical substances
99 The purpose of this test is to check if chemical substances which might be present in the vicinity of batteries
100 and have some chemical affinity to PP can significantly weaken the material properties.
101 The test shall be carried out on specimens 5A according to EN ISO 527-2. The specimens are prepared by
102 injection moulding and shall be aged at 100 °C for 4d before starting the test.
103 Each sample shall be weighed and all samples for one liquid are treated together under reflux at a
104 temperature and time according to Table 1.
105 In Annex E a laboratory equipment for heat treatment under reflux is depicted.
106 For statistical reasons the test shall be carried out on at least 6 samples
107 After treatment each sample shall be dried, weighed and tested on tensile strength at yield according to
108 EN ISO 527-1.
109 The maximum change in weight and tensile strength at yield compared to the initial data, before treatment
110 with chemicals, is given in Table 1.
