19、7Annex ZA (informative) Relationship between this International Standard and the Essential13iv Foreword 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 carri
20、ed out through ISO technical committees. Each member body interested 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. I
21、SO collaborates closely with the International Electrotechnical 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 Internati
22、onal Standards. Draft International Standards adopted by the 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 el
23、ements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9185 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 162, Protective clothing including hand and arm protectio
24、n and lifejackets, in collaboration with Technical Committee ISO/TC 94, Personal safety Protective clothing and equipment, Subcommittee SC 13, Protective clothing, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This second edition cancels and replac
25、es the first edition (ISO 9185:1990), which has been technically revised. This second edition includes the following significant technical changes compared to the first edition: a) new PVC sensor film included; b) Cryolite included as test metal. EN ISO 9185:2007vIntroduction ISO 9185:1990 and EN 37
26、3:1995 have been used up until now with reasonable success as the principle test methods for materials used in the manufacture of clothing to protect against large splashes of molten metals. EN and ISO specifications cite these test methods and set levels of performance in terms of the mass of iron
27、or aluminium that can be splashed onto test materials without producing damage to the heat sensor film. The revision of the test methods contained within this International Standard incorporates changes based on experience that are intended to improve reproducibility and to respond to incident data
28、from the aluminium smelter industry. A test procedure is therefore introduced to determine the protection provided by materials when splashed with molten cryolite. This revision also harmonises into one test procedure the previously slightly different procedures in ISO 9185 and EN 373 for testing wi
29、th molten aluminium. A new supply of PVC sensor film has been established together with a new world-wide distributor see note in the text. One single specification for PVC film replaces the previously different ones in ISO 9185 and EN 373. The test method in this International Standard is distinct f
30、rom that in ISO 9150, which assesses the protective performance of materials intended to be manufactured into protective clothing for welding activities. EN ISO 9185:2007blank1Protective clothing Assessment of resistance of materials to molten metal splash 1 Scope This International Standard specifi
31、es a method for assessing the heat penetration resistance of materials intended for use in clothing to protect against large splashes of molten metal. It provides specific procedures for assessing the effects of splashes of molten aluminium, molten cryolite, molten copper, molten iron and molten mil
32、d steel. The principle of the test method is applicable to a wider range of hot molten materials than those for which specific procedures are set out, provided that appropriate measures are applied to protect the test operator. It is important to note that good resistance of a material to a pure mol
33、ten metal does not guarantee a good performance against any slag that can be present in a manufacturing process. 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 referen
34、ces, the latest edition of the referenced document (including any amendments) applies. ISO 683-1:1987, Heat-treatable steels, alloy steels and free-cutting steels Part 1: Direct-hardening unalloyed and low-alloyed wrought steel in form of different black products 3 Terms and definitions For the purp
35、oses of this document, the following terms and definitions apply. 3.1 damage PVC sensor film any smoothing or modification to the embossing or pinholing of the PVC sensor film, extending in total for at least 5 mm across its width NOTE Where the visual change in appearance is in discrete spots, dama
36、ge occurs when the summation of the width of each spot exceeds 5 mm across any horizontal section. For cryolite, experience indicates that damage can be defined as less than 5 mm in width, but greater than 10 mm in length. 3.2 molten metal splash index figure equal to the minimum mass of molten meta
37、l poured which just causes damage to the PVC sensor film 4 Principle Materials are tested by pouring quantities of molten metal onto the test specimen supported at an angle to the horizontal on a pin frame. Damage is assessed by placing an embossed thermoplastic PVC sensor film directly behind, and
38、in contact with, the test specimen and noting changes to the film after pouring. Any adherence of the metal to the test specimen surface is also noted. Depending on the result, the test is repeated, using a greater or smaller mass of metal, until the minimum quantity to cause damage to the film is o

NOTE It is advisable that coarse filings or small pieces cut from solid bar or sheet be used, because fine filings
40、 have proved difficult to melt. A range of pouring temperatures used in industry for different metals and for cryolite is given in Annex A. 5.2 PVC sensor film 1), comprising an embossed PVC sheet, of mass per unit area (300 30) g/m2, which when tested as described in Annex B shows no smoothing or m
41、odification of the embossing of the central area at a block temperature of (166 2) C but which shows smoothing or modification of the central area at a block temperature of (183 2) C. The procedure set out in Annex B shall be undertaken no more than 30 days before any one day of testing in accordanc
42、e with this International Standard. NOTE The reason for this continuous calibration of the PVC sensor film is that it is likely to change over time because of plasticizer loss. It is advisable that the PVC sensor film be stored in a cool and dark location so as to minimize such changes. Because of t
43、he economics and consistency of production, one batch of at least 1500 m is produced and then used by test laboratories over a period of several years. 5.3 Crucible, whose approximate external dimensions are a height of 97 mm, a top diameter of 80 mm, a bottom diameter of 56 mm and a capacity (brim
44、full) of 190 ml (see Figure 1). NOTE For most molten metals, including iron, a graphite impregnated material (if an induction furnace is used) has been found suitable for the crucible. 5.4 Detachable crucible holder, to enable the crucible containing the molten metal to be moved quickly and safely f
45、rom the furnace to the test apparatus. 5.5 Furnace, capable of operating at a temperature 100 C above the pouring temperature specified in Annex A. The furnace type may be either a muffle furnace or an induction type furnace. NOTE Muffle furnaces are capable of holding at least four crucibles (i.e.
46、internal furnace size is typically 135 mm 190 mm 780 mm), but they take several hours to melt metals such as steel, iron and copper. Induction furnaces melt a single crucible of these metals in less than half an hour. 5.6 Temperature probe, either a small thermocouple 2)or an optical non-contact tem
47、perature device, capable of measuring molten metal temperatures up to 1 650 C to an accuracy of 10 C. 5.7 Pouring apparatus, shown in Figure 1, consisting of the pouring device, a means of rotating the pouring device at constant angular velocity, a specimen holder with supporting frame and a sand tr
48、ay. The pouring device, consisting of crucible holder and drive shaft, shall be designed and constructed so that the point at which the molten metal pours from the crucible lies on the axis of rotation of the drive shaft. The pouring device shall be manufactured from steel. 1) The PVC sensor film is
49、 supplied by Health b) the metal runs off the side of the test specimen or strikes within 25 mm of the top edge; c) any of the molten metal does not first hit the test specimen; d) the metal is not completely molten when poured; e) the PVC film ignites due to metal solidifying to the pin frame. 12 Test report The test report shall include the following: a) a reference to this International Standard; b) for each individual test specimen, the approximate mass of metal used (see 9.2), whether any molten metal adhered to the material, the res
