28、grades of deflection recovery are identified: ? grade 0: no performance requirement; ? grade 1: 30 % to 40 %; ? grade 2: 40 % to 50 %; ? 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 General A typical compressi
29、on block is shown in annex A. The compression block shall consist of a support for the gasket or weatherstripping such that one or more test pieces can be mounted separately or together in a manner that will allow them to be compressed or deflected to their minimum working width. 5.2 Heating chamber
30、 An electrically heated oven which complies with the requirements of ISO 188, method A is required for the test. It shall be capable 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 fo
31、llowing tolerances shall apply, unless otherwise stated: ? temperature in degrees Celsius (C) : 1 C; ? deflection in millimetres (mm) : 0,5 mm; ? relative humidity : 5 %.

32、6.2 Test samples 6.2.1 General Wherever possible, the time between 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 t
33、he sample without incurring more than the normal manufacturing variability. 6.2.2 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 Preparation of test pieces Test p
34、ieces 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 method 7.1 Temperature and humi
35、dity The standard laboratory temperature shall be either 23 C or 25 C, in accordance with national practice. The standard laboratory humidity shall be 45 % relative humidity at 23 C or 55% relative humidity at 25 C. 7.2 Determination of free height Measure the free height (a) of the test piece, with
36、out creating significant deformation, either before or after mounting the specimen in the test apparatus. A minimum of three measurements shall be taken. The free height of the test piece shall be determined within a limit deviation of 0,05 mm. If any results are beyond the permitted tolerance then
37、new test pieces shall be obtained. NOTE 1Suitable non-contact measuring equipment includes a shadowgraph, a 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 m
38、arkings used do not damage the test piece or disappear during heating. Alternatively, test pieces may be labelled after heating. 7.3 Deflection recovery test Mount test pieces in a suitable compression block as shown in annex A and compress to the minimum width (b); Heat the oven to the maximum temp
39、erature of the required grade, load the compression block and maintain the maximum working temperature for 22 h 2 0 ? h.

40、t ambient temperature for a minimum of 2 h. 7.4 Re-measurement of 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), perpendicular to the compressed surface, relative to a conveni
41、ent datum, to an accuracy of 0,05 mm, using the same equipment and method as 7.2. 7.5 Expression of results Results shall be expressed as a percentage in accordance with the following formula: Dr = ? ? ? ? ? ? ? R 1 W )a-(a 1 . 100 Where Dris the deflection recovery in %; ais the free height before
42、the test, in mm; a1is the height after the test, in mm; WRis the working range, in mm. The results of three specimen tests shall be computed and the average value recorded to one decimal point. 7.6 Determination of final result of samples After completing all three tests, the average percentage valu
43、e shall be calculated and recorded. 8 Test report A test report shall 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:
44、 a) place of test; b) person or body carrying out the assessment; 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.
