European foreword
This document (EN 50342-5:2025) has been prepared by CLC/TC 21X, ”Secondary cells and batteries”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2026-10-31
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2028-10-31
conflicting with this document have to be
withdrawn
This document supersedes EN 50342-5:2010 and all of its amendments and corrigenda (if any).
— improvement of the structure and the wording of the document;
— clear definition of tests and requirement levels that need to be passed to state EN 50342-5 compliance;
— separation between test procedures and requirements;
— differentiation between system level tests and requirements compared to component level tests and
requirements.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national committee. A
complete listing of these bodies can be found on the CENELEC website.
1 Scope
This document is applicable to housing and accessory parts of lead-acid batteries made of polypropylene.
Lead-acid batteries are used primarily as a power source for the starting of internal combustion engines,
lighting and for auxiliary equipment of road vehicles. These batteries are all referred to as starter batteries.
This document is applicable to starter batteries for passenger cars and for commercial or industrial vehicles.
Battery housing and accessory parts according to this document do not provide any protection of the
polypropylene against aging due to light. The parts are intended to be used within the engine compartment or
within battery boxes where they are protected from light.
The purpose of this document is to define requirements for raw material used to produce housing and
accessory parts for starter batteries, to define requirements of the physical properties of battery housing and
to define uniform test procedures for validation.
2 Normative references

4 General
This document provides test procedures and requirements for poly material, battery components and
complete batteries. To prove compliance with this document the tests according Annex A shall be passed.
5 Properties of raw materials
5.1 General
The examination of the raw materials should be performed in accordance to the specifications shown in
Annex B. If not agreed otherwise, the results need to be documented in a corresponding material
specification.
Test methods are based on international ISO standards. The needed specimens for the individual examination
are given in Annex B.
The specimens shall be stored before starting any test for at least 4 days at (23° ± 0,5) °C and shall be tested
within 3 months.
Annex C recommends possible test procedures for the material properties taken out of the battery housing,
without being normative.
5.2 Resistance against chemical substances
The purpose of this test is to check if chemical substances which might be present in the vicinity of batteries
and have some chemical affinity to PP can significantly weaken the material properties.
The test shall be carried out on specimens 5A according to EN ISO 527-2. The specimens are prepared by
injection moulding and shall be aged at 100 °C for 4d before starting the test.
Each sample shall be weighed and all samples for one liquid are treated together under reflux at a
temperature and time according to Table 1.
In Annex E a laboratory equipment for heat treatment under reflux is depicted.
For statistical reasons the test shall be carried out on at least 6 samples
After treatment each sample shall be dried, weighed and tested on tensile strength at yield according to
EN ISO 527-1.
The maximum change in weight and tensile strength at yield compared to the initial data, before treatment
with chemicals, is given in Table 1.
