24、rdization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right t
25、o be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Sta
26、ndards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an In
27、ternational Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

29、ive clothing, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This third edition cancels and replaces the second edition (ISO 6530:1990), which has been technically revised. ENISO6530:2005iv Introduction This International Standard specifies a test m
30、ethod for measuring indices of penetration, absorption and repellency for protective clothing materials against low-volume, low-pressure splashes of liquid chemicals, usually chemicals of low volatility. ISO 13994 may be used for determining the penetration resistance of protective clothing material
31、s against chemicals in larger volume and higher pressure splashes. Clothing made of these materials should not be used as the sole means of protection where resistance to permeation by chemicals at the molecular level (see ISO 6529) is essential and where a complete barrier to liquid (or gaseous) ch
32、emicals is required (e.g. risk of exposure to massive and forceful discharges of concentrated liquid chemicals). Data obtained by this test method may be used as a guide for screening protective clothing materials. Clothing, which has been developed from materials selected by this method of test sho
33、uld be used, therefore, only in well-defined circumstances when an evaluation of the finished item has indicated an acceptable level of performance (in laboratory and field-testing of a garment, consideration of exposure levels to specified chemicals, etc.). In interpreting the results of the test m
34、ethod, the influences of the physical properties of the test chemical (e.g. volatility) should also be taken into consideration.

35、uids 1 Scope This International Standard specifies a test method for the measurement of indices of penetration, absorption and repellency for protective clothing materials against liquid chemicals, mainly chemicals of low volatility. Two levels of the potential performance of materials are assessed
36、by this method of testing to meet with possible requirements for protection against a) deposition on the surface of a material, at minimal pressure, of spray droplets up to coalescence or occasional small drips; b) contamination by a single low-volume splash or low-pressure jet, allowing sufficient
37、time to divest the clothing or take other action as necessary to eliminate any hazard to the wearer from chemical retained by the protective garment, or, in circumstances where pressure is applied to liquid contaminants on the surface of the clothing material, as a result of natural movements of the
38、 wearer (flexing of contaminated areas of clothing at arms, knees, shoulders) and contact with contaminated surfaces (e.g. walking through sprayed foliage). 2 Definitions For the purpose of this document, the following terms and definitions apply. 2.1 penetration process by which a chemical moves th
39、rough pores, apertures or essential openings in a material or finished item of clothing NOTE The apertures can be the result of mechanical damage. 2.2 permeation process by which a chemical moves through a protective clothing material on a molecular level NOTE Permeation involves the following: a) s
40、orption of the molecules of the chemical onto the contact surface (outer surface) of the material; b) diffusion of the sorbed molecules into the material; c) desorption of the molecules from the opposite (inner) surface of the material. 2.3 repellency ability of a material to shed liquid that is app
41、lied to its surface ENISO6530:20052 3 Principle A measured volume of a test liquid is applied in the form of a fine stream or jet to the surface of a clothing material resting in an inclined gutter. Determination of the respective proportions of the applied liquid which penetrate a test specimen and
42、 which are repelled by its surface indicates the potential of the material for use in the described field of application. 4 Method 4.1 Apparatus The apparatus, as assembled (see Figure 1), shall comprise the following: rigid transparent gutter, of semi-cylindrical shape, with an internal diameter (1
43、25 5) mm, length (300 2) mm and inclination 45; rigid cover (not shown in Figure 1), semi-cylindrical in shape, length 270 mm, external diameter (105 5) mm and an evenly distributed mass of (140 7) g; hypodermic needle, bore (0,8 0,02) mm; length is not critical but the pointed tip shall be removed
44、and the end ground flat; syringe or other leak-free attachment to the needle, capable of delivering (10 0,5) cm 3of test liquid; motorized syringe-drive unit or a hydraulic pump or other pressurized system, to deliver the correct volume of test liquid (10 0,5) cm 3 in an unbroken stream or jet via t
45、he needle within (10 1) s; manual delivery or gravity shall not be used; WARNING Appropriate precautions applicable to the use of equipment under pressure and the forceful discharge of liquid chemicals should be taken. mounting device, for maintaining the hypodermic needle and attachments in their r
46、equired positions (see Figure 1); small beaker; balance, accurate to 0,01 g; transparent film, resistant to the test liquid; absorbent paper 1) , 0,15 mm to 0,2 mm thick; stopwatch, accurate to 0,1 s; temperature controlled room or cabinet, to enable tests to be carried out at temperatures other tha
47、n ambient. NOTE 1 The transparent film is to protect the gutter and obviate the need to rinse it between tests. NOTE 2 The filter paper will show any passage of the test liquid through the test specimen. The semi-cylindrical cover is used to maintain intimate contact between the contaminated area of
48、 the test specimen and the filter paper after release of the test liquid. 1) Filter paper Whatman no. 1 is found to be suitable for this purpose.

If necessary, and in particular for safety reasons, substitutes may be used, provided that it can be demonstrated that their results are similar to those of the chemicals against which protection is required.
