21、es). 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 to be represented on that committee. International organizations, governmental and

22、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 Standards are drafted in accordance with the rules given in the ISO/IEC Directives, P

23、art 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 International Standard requires approval by at least 75 % of the member bodies casti

24、ng 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. ISO 30013 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subco

26、11 All rights reserved 1Rubber and plastics hoses Methods of exposure to laboratory light sources Determination of changes in colour, appearance and other physical properties WARNING Persons using this International Standard should be familiar with normal laboratory practice. This standard does not

27、purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies methods for the ex

28、posure of rubber and plastics hoses to three types of laboratory light source (xenon-arc, fluorescent UV and open-flame carbon-arc lamps). These methods are designed to simulate the exposure of hoses used in an outdoor environment (exposure to xenon-arc lamps by method A, exposure to fluorescent UV

29、lamps by method A and exposure to open-flame carbon-arc lamps with type 1 filters) or in an indoor environment (exposure to xenon-arc lamps by method B, exposure to fluorescent UV lamps by method B and exposure to open-flame carbon-arc lamps with type 2 filters). Four types of test piece (two strain

30、ed and two unstrained upon exposure) are specified. Results from the three light sources and the different sets of exposure conditions specified are not comparable. 2 Normative references The following referenced documents are indispensable for the application of this document.

37、ypes of test piece 5.1.1 General Four types of test piece are detailed in Table 1. The type used shall be as specified in the product standard. Results obtained with the various types of test piece are not comparable, even for the same property. Table 1 Types of test piece Type 1 Type 2 Type 3 Type

BS EN ISO 30013:2011ISO 30013:2011(E) ISO 2011 All rights reserved 35.1.2 Type 1 The test piece shall cons

41、ist of a sample of hose. The length shall be calculated from the equation b22dLr d where L is the length, in mm, of the test piece; rbis the minimum bend radius, in mm, of the hose under test; d is the outside diameter, in mm, of the hose under test. Mount the test piece in a test piece holder as sh

42、own in Figure 1. The radius rbshall be equal to the specified minimum bend radius for the hose under test or, if this is not specified, six times the inside diameter. 5.1.3 Type 2 The test piece shall consist of a strip cut longitudinally from a hose. The strip shall be 150 mm in length and 25 mm in

43、 width. Mount the test piece in a test piece holder as shown in Figure 2, in such a way that the convex side will be exposed to the light during the exposure. For details of the mounting of the test piece, see method 2 in ISO 7326:2006. 5.1.4 Type 3 The test piece shall normally consist of a strip o

44、f hose cover, cut longitudinally from the hose. The strip shall be 100 mm in length and 25 mm in width. If a hose cover test piece cannot easily be cut from the hose, the test piece shall consist of a strip cut longitudinally from the complete hose with its cover in place. The strip shall be 100 mm

45、in length and 25 mm in width. Mount the test piece in a test piece holder as shown in Figure 3, in such a way that the convex side will be exposed to the light during the exposure. 5.1.5 Type 4 The test piece shall consist of a sample of hose approximately 150 mm in length. If possible, test pieces

46、shall be cut from different sections of the hose (e.g. from each end and from the middle). Mount each test piece in a test piece holder as shown in Figure 4, ensuring that it is not subject to any stress but curves naturally in such a way that the convex side will be exposed to the light during the

47、exposure. 5.2 Conditioning Prior to testing, condition the test pieces, mounted as described in 7.2, under the applicable standard conditions as specified in ISO 23529 or ISO 291, as appropriate, in darkness or subdued light.

48、mber of test pieces At least three test pieces shall be exposed to laboratory light sources, and at least one piece shall be kept in darkness as a control in order to permit the evaluation of the change in colour, appearance and physical properties. The total number of test pieces will therefore be

49、at least four. 5.4 Test piece holders The test piece holders may be used in each type of test piece. The holder shall be constructed with inert materials that do not affect the results, e.g. aluminium or stainless steel. They are also designed to support the back of the test piece. Brass, steel and copper shall not be used near to the test piece. 5.5 Radiation direction and radiation surface Test pieces shall be attached to the appropriate holder shown in Figure 1 t
