31、d ISO 3386-1:1986 Polymeric materials, cellular flexible Determination of stress-strain DIN EN ISO 3386-1:2015-10EN ISO 3386-1:1997 + A1:2010 (E)4 1 Scope This part of ISO 3386 specifies a method for the determination of the compression stress/strain characteristic of low-density flexible cellular m

32、aterials up to 250 kg/m3. lt also indicates a method for the calculation of the compression stress value of such materials. The compression stress/strain characteristic is a measure of the load-bearing properties of the material, though not necessarily of its capacity to sustain a long-term load. Th

33、e compression stress/strain characteristic differs from the indentation hardness characteristics (as determined in accordance with ISO 2439), which are known to be influenced by the thickness and the tensile properties of the flexible cellular material under test, by the shape of the compression pla

34、te and by the shape and size of the test piece. ISO 3386/2 specifies a method for high-density materials and differs from part 1 in the following ways : it is mainly concerned with materials of density above compression stress values have been deleted; it does not permit the use of a cylindrical tes

35、t piece. 2 Normative references ISO 1923, Cellular materials Determination of linear dimensions ISO 2439, Polymeric materials, cellular flexible Determination of hardness (indentation technique) !ISO 7500-1, Metallic materials Verification of static uniaxial testing machines Part 1: Tension/ compres

38、5-10 EN ISO 3386-1:1997 + A1:2010 (E)5 4 Apparatus 4.1 Test machine The test machine shall be capable of compressing the test piece between a support surface (see 4.2) and a compression plate (see 4.3), which shall have a uniform relative rate of motion in the vertical direction of (100 20) mm/min.

39、!The test machine shall be capable of measuring the force with an accuracy corresponding to class 1 of ISO 7500-1 or with an accuracy of 1 N, and also of measuring the test piece thickness under load with an accuracy of 0,25 mm.“ 4.2 Supporting surface Unless otherwise specified, the test piece shal

40、l be supported an a smooth, flat, horizontal and rigid surface, larger than the test piece, which may be vented with holes about 6 mm in diameter, and approximately 20 mm pitch, to allow the escape of air from below the test piece. 4.3 Compression plate The compression plate shall be of any convenie

41、nt size and shape, provided that it overlaps the test piece in all directions. The lower surface shall be plane and smooth, but not polished, and it shall be maintained parallel to the supporting surface. 5 Test pieces 5.1 Form and dimensions The test piece shall be a right parallelepiped or a right

42、 cylinder with a minimum width or diameter/thickness ratio of 2 : 1. The preferred thickness of a test piece is (50 1) mm and in any case the thickness shall be not less than 10 mm. Sheets less than 10 mm thick shall be plied together to reach the preferred thickness range, provided that a minimum o

43、f ten cell diameters are included in the thickness of each ply. The area of the test piece shall be not less than 2 500 mm2and shall be such that at no point does the test piece overlap the compression plate. NOTE For specimens with an area close to the lower limit, the compression forces may be ver

44、y low, and specialized testing equipment may therefore be required to meet the precision specified in 4.1. 5.2 Samples showing orientation If the products show an orientation of the cellular structure, the direction in which the indentation is to be carried out shall be agreed upon between the inter

45、ested parties. Normally, testing is carried out in that direction in which the finished product will be stressed under service conditions. 5.3 Number of test pieces Three test pieces shall be tested. 5.4 Conditioning !Materials shall not be tested less than 72 h after manufacture unless it can be de

46、monstrated that the mean results obtained at either 16 h or 48 h after manufacture do not differ by more than 10 % from those obtained after 72 h, in which case testing is permitted at 16 h or 48 h, respectively. DIN EN ISO 3386-1:2015-10EN ISO 3386-1:1997 + A1:2010 (E)6 Prior to the test, the test

47、pieces shall be conditioned, undeflected and undistorted, for at least 16 h in one of the following atmospheres: 23 C 2 C, (50 5) % relative humidity; 27 C 2 C, (65 5) % relative humidity. This conditioning period can form the final part of or, in the case of testing 16 h after manufacture, the whol

48、e of the period following manufacture. In the case of quality-control tests, test pieces can be taken a shorter time (down to a minimum of 12 h) after manufacture and testing carried out after conditioning for a shorter period (down to a minimum of 6 h) in one of the atmospheres specified above. Testing shall be carried out at the same temperature and relative humidity as those used for conditioning.“ 6 Procedure Measure the dimensions of the test piece using
