16、E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) 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 int

17、erested in a subject for which a technical committee has been established has the right to 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 Electrotechnic

18、al Commission (IEC) on all matters of electrotechnical standardization. International Standards 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

19、technical committees are circulated to the member bodies for voting. Publication as an International 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.

20、ISO shall not be held responsible for identifying any or all such patent rights. ISO 14419 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finishing and water resistance tests. This second edition cancels and replaces the first edition (ISO 14419:1998), of whic

21、h it constitutes a minor revision. It also incorporates Technical Corrigendum ISO 14419:1998/Cor.1:2004. BS EN ISO 14419:2010INTERNATIONAL STANDARD ISO 14419:2010(E) ISO 2010 All rights reserved 1Textiles Oil repellency Hydrocarbon resistance test 1 Scope This International Standard is applicable to

22、 the evaluation of a substrates resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions. This International Standard is intended to provide a guide to oil stain resistance. It can provide a rough index of oil stain resistance as, generally, the higher the o

23、il repellency grade, the better resistance to staining by oily materials, especially liquid oil substances. This is particularly true when comparing various finishes for a given substrate. This International Standard can also be utilized in determining if washing and/or drycleaning treatments have a

24、ny adverse effect on the oil repellency characteristics of a substrate. NOTE 1 Washing and drycleaning treatment procedures are described in ISO 6330 or ISO 3175 (all parts), respectively. This International Standard is not intended to give an absolute measure of the resistance of the substrate to s

25、taining by all oily materials. Other factors, such as composition and viscosity of the oily substances, substrate construction, fibre type, dyes and other finishing agents, also influence stain resistance. This International Standard is not intended to estimate the resistance to penetration of the s

26、ubstrate by oil-based chemicals. NOTE 2 For the evaluation of the resistance to penetration of the substrate by oil-based chemicals, see ISO 6530. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition

27、cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

30、t angle. The oil repellency grade is the highest numbered test liquid which is not absorbed by the substrate surface. 5 Safety precautions SAFETY PRECAUTIONS These safety precautions are for information purposes only. The precautions are ancillary to the testing procedures and are not intended to be

31、 all inclusive. It is the users responsibility to use safe and proper techniques in handling materials in this International Standard. Manufacturers should be consulted for specific detail such as material safety data sheets and other manufacturers recommendations. 5.1 Good laboratory practices shou

32、ld be followed. Wear safety glasses and impervious gloves when handling test liquids in all laboratory areas. 5.2 Some of the hydrocarbons specified in this International Standard are flammable. Keep away from heat, sparks and open flame. Use with adequate ventilation. Avoid prolonged breathing of v

33、apour or contact with skin. Do not take internally. 6 Reagents All reagents shall be of a suitable analytical grade. Ensure the standard test liquids are used and stored at a temperature of (20 2) C. All reagents and standard test liquids have a maximum shelf life of three years. 6.1 Test liquids, p

34、repared and numbered according to Table 1. The purity of test liquids affects surface tension of the liquid. Use only analytical grades of test liquids. 6.2 White mineral oil, USP white mineral oil 340-355 SSU at 37,8 C with Saybolt colour +30. Table 1 Standard test liquids Composition Oil test liqu

A

37、 typical system found useful consists of 60 ml dropping bottles with ground-in pipettes and neoprene bulbs. Prior to use, the bulbs should be soaked in heptane for several hours and then rinsed in fresh heptane to remove soluble substances. It has been found helpful to place the test liquids in sequ

38、ential order on a wooden platform on the grading table. 7.2 White textile blotting paper, of approximately (0,71 0,1) mm in thickness, weight of (370 5 %) g/m2and an absorbent capacity of (220 30) %.1)7.3 Laboratory gloves of general purpose are sufficient. 8 Test specimens Three test specimens of a

39、pproximately 20 cm 20 cm are needed. Test specimen size should be chosen to represent all physical and colour characteristics of the fabric and allow ample room for testing. Condition the test specimens for a minimum of 4 h at (20 2) C and (65 4) % RH prior to testing. See ISO 139. 9 Procedure 9.1 P

40、lace the first test specimen flat on the white textile blotting paper (7.2) on a smooth, horizontal surface with the face side on top. Testing should be conducted in standard atmosphere for testing in accordance with ISO 139. Testing should be completed within 30 min, if test specimens are removed f

41、rom a conditioning chamber. 9.1.1 When evaluating open-weave or “thin” substrates, place the test specimen on at least two layers of the substrate; otherwise, the test liquid can wet the underlying surface, not the actual test substrate, and thereby cause confusion in the reading of the results. 9.1

42、.2 Equipment, benches and gloves should be free of silicone. Use of silicone-containing products could adversely affect oil repellency grades. 9.2 Wearing clean laboratory gloves (7.3), brush the pile of napped or pile substrates using the hand, in the direction giving the greatest lay of the surfac

43、e prior to placing the drops of the test liquid. (The direction giving the lowest pile.) 9.3 Beginning with the lowest-numbered test liquid (oil test liquid No. 1), carefully place small drops (approximately 5 mm in diameter or 0,05 ml volume) on the test specimen in a minimum of five locations repr

44、esenting all physical and colour characteristics of the fabric. The drops should be approximately 4,0 cm apart. The dropper tip should be held at a height of approximately 0,6 cm from the substrate surface while placing drops. Do not touch the substrate with the dropper tip. Observe the drops for (3

45、0 2) s from approximately a 45 angle. Assess each drop in accordance with Figure 1. Immediately examine the reverse of the fabric for any wetting. 1) White Textile Blotting Paper is the trade name of a product supplied by the American Association of Textile Chemists and Colorists (AATCC), P.O.

48、ous test and again observe for (30 2) s. Assess each drop in accordance with Figure 1. Immediately examine the reverse of the fabric for any wetting. 9.5 Continue this procedure until one of the test liquids shows obvious wetting or wicking of the substrate under or around the drop within (30 2) s.

49、A maximum of six tests (oil test liquids) may be performed on one test specimen. 9.6 Repeat the procedure with the second sample. A third sample may be required (see Clause 11). 10 Evaluation 10.1 The oil repellency grade of a substrate is the numerical value of the highest-numbered test liquid which will not wet the substrate within a period of (30 2) s. A grade of zero (0) is assigned when the substrate fails the white mineral oil liquid test. Wetting of the substrate is normally evidenced by a darkening
