DS/ISO 7267/2:1987 橡胶包覆的辊筒. 表观硬度的测定.第2部分: 肖氏(SHORE)硬度计法

This part of ISO 7267 specifies a method for the determination of the apparent hardness of vulcanized rubber roller covers, expressed in Shore hardness, for measurement where only medium precision is required. The method and apparatus used are essentially those described in ISO 7619, the measurements in this case being made on the curved surface of the conditioned rubber covered roller rather than on a flat test piece. Shore- type A and D instruments are specified, the latter being used for measurements on rollers of high hardness.

DS/ISO 7267/1:1987 橡胶包覆的辊筒. 表观硬度的测定.第1部分: 国际橡胶硬度标度(IRHD)法

This part of ISO 7267 specifies a method for the determination of the apparent hardness of vulcanized rubber roller covers, expressed in international rubber hardness degrees (IRHD). The method is similar in principle to the methods used for the determination of the hardness of rubber vulcanizates in ISO 48, ISO 1400 and ISO 1818 in that it consists essentially of measuring the depth of penetration of a spherical indentor operating under a specified force. The apparatus used is similar to that described in ISO 48, ISO 1400 and ISO 1818, differing only in that the base is designed specifically for application to roller covers and similar curved surfaces.

DS/ISO 7326:1986 橡胶和塑料软管;静态条件下的耐臭氧性试验的评定

This International Standard specifies three methods for deter-mining the resistance of the outer covers of hoses to ozone: method 1 - for bore sizes up to and including 25 mm carried out on the hose itself; method 2 - for bore sizes greater than 25 mm carried out on a test piece from the hose wall; method 3 - for bore sizes greater than 25 mm carried out on a test piece from the cover. Methods 1 or 2 should normally be used. Method 3 should be used only if it is not possible to carry out the test in accordance with method 2. NOTE — For hoses with built-in fittings from which it is not possible to take test pieces, the ozone resistance may be assessed on slabs in accordance with ISO 1431/1, using test sheets of the appropriate polymeric compound vulcanized to the same degree.

DS/ISO 8033:1986 橡胶和塑料软管. 构件间粘合力的测定

This International Standard specifies methods for the determination of the adhesion between lining and reinforcement, cover and reinforcement and between reinforcement layers. It covers all bore sizes and the following types of hose construction: — woven textile fabric — braided yarns — spiralled yarns — knitted yarns — circular woven yarns — textile cord fabric — braided wires — spiralled wires — hoses containing a supporting helix

DS/ISO 6801:1984 橡胶或塑料软管. 容积膨胀的测定

This International Standard specifies a method for the determination of the volumetric expansion of rubber or plastics hoses under hydrostatic pressure. This International Standard does not specify the dimensions of the test piece and the test pressure(s) as each of whieh will be specified in the appropriate specification.

DS/ISO 1746:1984 橡胶或塑料软管及导管. 弯曲试验

This International Standard specifies two methods for the determination of the behaviour of rubber or plastics hoses or tubing when bent to a specified radius. Method A is suitable for hoses and tubing of bore sizes up to about 80 mm; the size of the apparatus for testing hoses and tubing of larger bore sizes becomes excessive. The method also provides a means of measuring the force required to reach a specified bend radius, and the test may be carried out at a specified internal pressure. In method B, the bending characteristics, including the force required for bending, may be determined over a range of temperatures from -60 °C to +200 °C. The nature of the apparatus, however, limits its applicability to hoses and tubing of small bore sizes, i.e. up to about 12,5 mm.

DS/ISO 6945:1984 橡胶软管. 外包覆层的抗磨损测定

This International Standard specifies a method for the determination of the abrasion resistance of the outer cover of rubber hoses. This method is intended primarily for testing hydraulic hoses having textile or wire reinforcement and a nominally smooth and parallel cover, and other hoses of a similar type. The method is not intended for predicting product abrasion life, but is suitable for the comparison of quality levels. This International Standard does not specify the number of cycles which should be completed in each test; this number will be specified in the appropriate product specification.
