19、r lead-acid batteries as an energy storage device for cranking combustion engines, for lighting and for additional equipment used in road vehicles. These batteries are all referred to as starter batteries. This European Standard describes battery housings for batteries usable within the engine compa
20、rtment and for installation under conditions where they are protected from light. Batteries of this European Standard do not provide additional features for special protection from light. Therefore, batteries with limited protection from light are to be treated as a special case. The purpose of this
21、 European Standard is to describe the properties of battery housings for its use in combustion vehicles by means of uniform examination procedures and by defining the requirements for the raw material and the complete part. The test procedure and requirements for the complete housing are described i
22、n the main part. Test procedures for the raw material are determined in Annex A. Annex B recommends possible test procedures for the material properties taken out of the complete housings, without being normative. 2 Normative references The following referenced documents are indispensable for the ap

27、ls has to be performed by the supplier of the raw material in accordance to specifications of Annex A and, if not agreed otherwise, be documented in the material specification of a new PP material to be purchased. These examinations are preferably ISO Standards. The specimens shall be selected accor
28、ding to the specifications in Annex A and the tests are to be carried out according to the specifications in Annex A. For documentation the form of Annex A shall be used. The samples must be aged before starting the test for at least 4 days at (23 0,5) C and must be tested within 3 months. The mater
29、ial properties which have only low impact on the complete housing properties, e. g. due to the design of the battery housing, are mentioned in the annexes only for information. 4.2.2 Examination on resistance against chemical substances The purpose of this test is to check if chemical substances whi
30、ch can occur 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. The specimens are prepared by injection moulding and must be aged at 100 C for 4d before starting t
31、he test. Each sample has to 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 s
32、amples. After treatment each sample shall be dried, weighed and then tested on tensile according to EN ISO 527. The maximum change in weight and tensile strength at yield relative in % to the initial data before treatment with chemicals is given in Table 1. Table 1 Resistance against chemicals Subst

To differentiate between r
47、andom results and real effects the amount of samples for a clear decision should range at 10 samples at least. With only one sample it is statistically impossible to make a reliable decision.

48、10 mm thickness Cooling device of appropriate size, in order to store 10 containers and the steel plate D.3 Procedure The test is done at (-30 3) C. The test is done with at least 10 containers because of statistic evaluation. If the containers are injected with a multi cavity mould, it might be nec
49、essary to check 5 containers of each cavity. The 10 containers and the steal plate are cooled to (-30 3) C for at least 6 h. The ball is dropped from a height of 30 cm, once on the centre of each cell of the bottom of the container. If the injection points are located in the middle of the cell, the ball is dropped approximately 4 cm from the injection points (see Figure D.1). Dont d
