10、iiForeword 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 interested in a subject for which a
11、 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 Electrotechnical Commission (IEC) on all matte
12、rs 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 technical committees are circula
13、ted 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. ISO shall not be held responsibl
14、e for identifying any or all such patent rights. ISO 25518 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses).

15、bber gloves for general applications Specification WARNING Persons using this International Standard should be familiar with normal laboratory practices. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to est
16、ablish appropriate safety and health practices and to ensure compliance with any regulatory conditions. 1 Scope This International Standard specifies the physical requirements and methods of sampling and testing for single-use rubber gloves, made from natural rubber latex, synthetic rubber latex or
17、rubber solution, intended for general applications, but not gloves intended for medical purposes. It does not cover the safe and proper usage of the gloves. 2 Normative references The following referenced documents are indispensable for the application of this document.

Any pigment, surface treatment, lubricant or pow
20、der used shall be non-toxic and shall be disclosed on request. Substances used for the treatment that could be transferred to the skin during use shall not cause any harm. 3.2 Dimensions When measured at the points shown in Figure 1, gloves shall comply with the dimensions for length and palm width
21、given in Table 1, using the inspection level and AQL given in Table 3. The measurement of length shall be the shortest distance between the tip of the second finger and the cuff end. The length measurement may be taken by hanging the glove on a suitable mandrel with a tip radius of 5 mm. The measure
22、ment of width shall be at the midpoint between the base of the index finger and the base of the thumb. The width measurement shall be made with the glove placed on a flat surface.

Test pieces shall be taken from the palm or back of the gloves. 3.4.2 Force at break an
26、d elongation at break When determined in accordance with the method specified in ISO 37, using type 2 dumb-bell test pieces, the force at break and elongation at break shall comply with the requirements given in Table 2, using the inspection level and AQL given in Table 3. Table 2 Tensile properties
27、 Property Requirement Minimum force at break before accelerated ageing, N 7,0 Minimum elongation at break before accelerated ageing, % 500 Minimum force at break after accelerated ageing, N 6,0 Minimum elongation at break after accelerated ageing, % 400 3.5 Accelerated ageing Accelerated ageing shal
28、l be conducted in accordance with the method specified in ISO 188. Test pieces can be prepared either by ageing the gloves at 70 C 2 C for 168 h 2 h or at 100 C 2 C for 22 h and cutting the test pieces from the aged gloves, or by cutting the test pieces from unaged gloves and ageing the test pieces
29、at 70 C 2 C for 168 h 2 h or at 100 C 2 C for 22 h. Tensile testing is then conducted as described in 3.4. The results shall comply with the requirements given in Table 2, using the inspection level and AQL as in Table 3. 4 Sampling and inspection For referee purposes, gloves shall be sampled and in
30、spected in accordance with ISO 2859-1. The inspection levels and acceptance quality limits (AQLs) shall conform to those specified in Table 3 for the characteristics listed. When a lot size cannot be determined, a lot of 35 001 to 150 000 shall be assumed. Table 3 Inspection levels and AQLs Characte

35、for watertightness A.1 Apparatus A.1.1 Circular hollow mandrel, of minimum external diameter 60 mm and adequate length to hold the glove and, with the glove attached, to accommodate 1 000 cm3of water. An example is given in Figure A.1. NOTE A transparent circular hollow mandrel would be suitable. Di

37、. Figure A.2 Holding device A.1.3 Graduated cylinder, capacity of at least 1 000 cm3, or other dispensing apparatus capable of delivering 1 000 cm3of water at a time. A.2 Procedure Attach the glove to the circular hollow mandrel with a suitable device, e.g. an O-ring, so that the glove does not exte
38、nd more than 40 mm over the mandrel. Introduce 1 000 cm3 50 cm3of water at a maximum temperature of 36 C into the hollow mandrel. Remove water that has inadvertently splashed onto the outside of the glove. If the water does not rise to within 40 mm of the cuff end, raise the glove to ensure that the
39、 whole of the glove, excluding the part 40 mm from the cuff end, is tested. Note any leaks immediately evident. If the glove does not leak immediately, make a second observation for leaks 2 min to 4 min after pouring the water into the glove. Disregard leakage within 40 mm of the cuff end. To assist
40、 observation, the water may be coloured with a water-soluble dye.
