30、grade 3: 50 % to 60 %; grade 4: 60 % to 70 %; grade 5: 70 % to 80 %; grade 6: 80 % to 90 %; grade 7: 90 %. 5 Test apparatus 5.1 Compression block A typical compression block is shown in annex A. The compression block shall consist of a support for two test pieces of standard extrusion, which will al
31、low them to be compressed uniformly to a fixed height of 60 % of the original free height of the specimen i.e. 9 mm 0,1 mm for the standard shape. 5.2 Heating chamber An electrically heated oven, which complies with the requirements of ISO 188, method A, is required for the test. It shall be capable
32、 of being set and maintained at the maximum working temperature of any materials to be tested. 6 Test procedure 6.1 Test measurements Throughout this test method the following tolerances shall apply, unless otherwise stated: temperature in degrees Celsius (C) : 1 C; compression in mm : 0,05 mm; rela
33、tive humidity : 5 %. Times shall be measured using a clock capable of recording a minimum of 576 h (24 days).

34、tween forming and testing shall not exceed 3 months. Every care shall be taken to ensure that samples arrive at the Test House in a pristine and fully testable condition. NOTEThis is to ensure that test pieces can be cut from any part of the sample without incurring more than the normal manufacturin
35、g variability. 6.2.2 Shape and size of test sample Tubular test samples prepared from the material used in the manufacture of gaskets/ weatherstripping tested to the requirements of prEN 12365-2 and -3, and obtained under conditions that have been shown by experience to give comparable results, shal
36、l be supplied in the standard cross section shown in Figure 1. Figure 1 Tubular shape for test samples 6.2.3 Conditioning Test samples shall be stored in a relaxed state in air at 23 C 2 C and a relative humidity of 50 % 5 %, for not less than 24 h and not more than 6 days, prior to test. 6.3 Prepar
37、ation of test pieces Test pieces with a minimum length of 100 mm and a maximum length of 500 mm shall be cut from various positions within the sample submitted for test. Care shall be taken to ensure that the test pieces have a good smooth finish and are free of blemishes or other flaws. 7 Test meth
38、od 7.1 General In this method, test pieces are subjected to the same maximum working temperature as they would in service, to simulate accelerated ageing. Two or more test pieces shall be used in each test. 7.2 Temperature and humidity The standard laboratory temperature shall be either 23 C or 25 C
39、, in accordance with national practice. The standard laboratory humidity shall be 45 % relative humidity at 23 C or 55 % relative humidity at 25 C.

40、ee height Measure the maximum free height of the test piece, perpendicular to the compressing surface, relative to a convenient datum, to a limit deviation of 0,05 mm, before commencing the test. Due to possible non-circular inaccuracy, this shall be determined by measuring the outside diameter thre
41、e times at different positions along the length. This can either be done before mounting the test piece on the test block, or prior to fitting the compression plate. The average free height (a) shall be calculated and recorded. NOTE 1Suitable non-contact measuring equipment includes a shadowgraph, a
42、 laser light beam device or a travelling microscope. Test pieces shall be labelled and marked to indicate the part of the surface which is uppermost. NOTE 2Care should be taken to ensure that markings used do not damage the test piece or disappear during heating. Alternatively, test pieces may be la
43、belled after heating. 7.4 Deflection recovery test Mount test pieces in a suitable compression block as shown in annex A and compress to a height of 9 mm 0,1 mm. Heat the oven to the maximum temperature of the required grade, load the compression block and maintain the maximum working temperature fo
44、r 504 h 2 h. Remove the block from the oven and allow cooling at ambient temperature for a minimum of 2 h. 7.5 Re-measure free height Maintain the test pieces, in a horizontal stress free condition with the working face uppermost, for 22 h 2 0 + h. Measure and record the new free height (a1), perpen
45、dicular to the compressed surface, relative to a convenient datum, to a limit deviation of 0,05 mm, using the same equipment and method as 7.3.

46、he results shall be expressed as a percentage in accordance with the following formula: RAA = 9)(a )a-(a 1 1 . 100 where RAAis the recovery, after accelerated ageing, in %; ais the height before the test, in mm; a1is the height after, test, in mm; ?is the spacer height, in mm. All the above test pro
47、cedures shall be repeated for each of not less than three specimens of the same standard tubular shape. 7.7 Determination of final result After completing all three tests, the average percentage value shall be calculated and recorded to an accuracy of one decimal place. 8 Test report A test report s
48、hall be prepared which identifies the specimen(s) and records the performance level achieved together with the details of tests used in the assessment of that performance. The following information shall be included in the test report: a) place of test; b) person or body carrying out the assessment;
49、 c) product designation according to the manufacturers standard literature; d) test results and any measurements or observations made at the time of the test; e) date and signature.
