25、s Test methods for nonwovens Part 5: Determination of resistance to mechanical penetration (ball burst procedure) 1 Scope This part of ISO 9073 specifies a method for determining the resistance to mechanical penetration of nonwoven fabrics by a ball of a given diameter. The method is primarily desig
26、ned to be used on nonwovens with some degree of elasticity, for which a regular burst test is not applicable. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references
27、, the latest edition of the referenced document (including any amendments) applies.

31、 lower, fixed, clamp of a constant-rate-of-traverse (CRT) tensile-testing machine (see Figure 1). A force is exerted vertically downwards against the specimen by a polished hardened-steel ball that is attached in the position of the upper, movable, clamp. The test is terminated when the ball rupture
32、s the material. 5 Apparatus 5.1 Constant-rate-of-traverse (CRT) tensile-testing machine, converted for use in the compression mode and fitted with a ball burst attachment (5.2) replacing the two clamp assemblies (see Figure 1). 5.2 Ball burst attachment, consisting of a) a polished steel ball (5.3)
33、that replaces the upper, moving, clamp of the tensile-testing machine; b) a ring-clamp mechanism (5.4) that replaces the lower, fixed, clamp of the tensile-testing machine. 5.3 Polished steel ball, having a diameter of (25,400 0,005) mm and spherical to within 0,005 mm. The size of the ball may diff
34、er from that stated if so agreed upon by all interested parties and recorded in the test report. 5.4 Ring clamp, having an internal diameter of (44,500 0,025) mm. The size of the ring clamp may differ from that stated if so agreed upon by all interested parties and recorded in the test report. Figur
35、e 1 Apparatus BS EN ISO 9073-5:2008ISO 9073-5:2008(E) ISO 2008 All rights reserved 36 Procedure 6.1 Specimens shall be selected in accordance with ISO 186. Bring the specimens from the prevailing atmosphere to moisture equilibrium for testing in the standard atmosphere as prescribed in ISO 139. If a
36、greed upon by all parties, conditioning and testing may be carried out without preconditioning the test specimens. Care in handling shall be observed so that test specimens do not contact any contaminants such as soap, salt, oil, etc., which might facilitate or hinder water penetration. No dirt or o
37、ther foreign material shall be allowed on the specimen. Do not write on the test area of the specimen. 6.2 Each test specimen shall be at least 125 mm square or a circle at least 125 mm in diameter. Test specimens need not be cut for testing. Take no specimens nearer to the edge of the fabric than 3
38、00 mm. 6.3 Unless otherwise agreed upon and recorded in the test report, as when specified in an applicable material specification, take five test specimens from the laboratory sample(s) of fabric. 6.4 Metrological confirmation of the test apparatus shall be in compliance with Clause 7, Figure 2 and
39、 Annex A of ISO 10012:2003. Also take into account the following: Set-up procedures for machines from different manufacturers may vary. Prepare the machine and verify its calibration as directed in the manufacturers instructions (see also Annex B). Set the distance for the travel of the ball so that
40、 it penetrates the test material but does not come in contact with the lower stage (very important). Set the testing machine for a crosshead speed of (300 10) mm/min unless otherwise specified and agreed upon by all parties. 6.5 Verify the total operating system by testing specimens of a standard ma
41、terial for ball burst and comparing the data obtained with historical data from the same standard material. It is recommended that this verification of the system be carried out on a daily basis before use, but at a minimum it should be done weekly. In addition, the total operating system should be
42、verified whenever there are changes in the load cells. Select and prepare a standard material which has a ball burst strength in the range of interest. Test the standard-material specimens in the same manner as unknown specimens (see 6.6). Determine the bursting force for each standard-material spec
43、imen, the mean value and the standard deviation from the mean. Compare the new data with previous data for the same material. If any of the data values are outside the tolerances established, recheck the total system to locate the cause for the deviation. Do not start testing until the results of st
44、andard-material testing are within these tolerances. 6.6 Place a specimen under tension in the ring clamp and fasten it securely by means of the screws or pneumatic mechanism. Start the CRT machine, using a downward crosshead speed of (300 10) mm/min and continue at that speed until the specimen bur
45、sts. Record, to the nearest 5 N, the ball burst strength of the specimen. 6.7 Ignore any failure that is confined to the edge of the clamp and repeat the test on another test specimen. Ignore any test result where the test specimen slips in the clamp and repeat the test on another test specimen. NOT
46、E Slippage is normally evident as blurring of the marks left by the ring clamp on the test specimen.
