7、(ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a BritishStandard without deviation. Some terminology and certain conventions are not identical with those used in BritishStandards; attention is drawn especially to the follow
8、ing. Wherever the words “International Standard” appear, referring to this standard, they should be read as “BritishStandard”. The comma has been used as a decimal marker. In BritishStandards it is current practice to use a full point on the baseline as the decimal marker. Cross-references. ISO1176
9、“Road vehicles masses vocabulary” referred to in clause2 is in course of preparation and is a revision of ISO1176:1974. The technical committee has reviewed the provisions of ISO1176:1974 “Road vehicles weights vocabulary” together with those of ISO3833:1977, referred to in clause2, and has decided
10、that they are acceptable for use in conjunction with this standard. There are no related BritishStandards to these two standards. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compl
11、iance with a British Standard does not of itself confer immunity from legal obligations.

12、This will be indicated in the amendment table on the inside front cover.BSAU188:1983 BSI 02-2000 1 1 Scope This International Standard specifies the characteristics of the towing anchorages mounted on road vehicles, allowing them to be towed or to tow another vehicle by means of towing ropes, cables
13、 or bars at the vehicle manufacturers option. 2 Field of application This International Standard applies to passenger cars as defined in ISO3833 and to other vehicles which have a maximum authorized total weight not exceeding3,5tonnes. 3 References ISO1176, Road vehicles Masses Vocabulary 1) . ISO38
14、33, Road vehiclesTypes Terms and definitions. 4 Definitions 4.1 anchorage device fixed to the vehicle or capable of being easily hooked, allowing the temporary attachment of a rope, a cable or a bar provided for towing 4.2 kerb mass as defined in ISO1176 4.3 maximum authorized total mass as defined
15、in ISO1176 5 Location 5.1 Unless they are removable, the anchorages shall not project, in the horizontal plane, beyond the exterior contour of the vehicle (body plus bumpers). 5.2 Each towing anchorage shall be located in such a way that the requirements of clause9 are fulfilled when a displacement
16、of 5 vertically and 25 horizontally occurs at the other end of the connecting element recommended by the vehicle manufacturer. These angles are measured from a horizontal line parallel to the middle plane of the vehicle through the anchorage in question. 6 Shape The shape of the anchorages is left t
17、o the manufacturers option. It shall permit the attachment, without the aid of tools or auxiliary parts. The smallest dimension of the working aperture shall not be less than25mm. The anchorages shall not damage the ropes or cables during towing. 7 Strength The anchorage shall withstand a static loa
18、d of at least half the maximum authorized total mass according to clause8. 8 Testing 8.1 Test conditions The vehicle shall be appropriately secured at kerb weight position as specified by the vehicle manufacturer, on a horizontal rigid surface. The vehicle manufacturer is allowed if he desires, to c
19、arry out the test on the structure of the vehicle, provided that equivalence is demonstrated with the complete vehicle. 8.2 Test procedure 8.2.1 The anchorage shall be subjected to two tests, each consisting of a static tractive force equal to half the maximum authorized total weight. 8.2.2 The stat
20、ic tractive load shall be applied in the forward direction for the anchorages mounted at the front of the vehicle and in the rearward direction for anchorages mounted at the rear. 8.2.3 The first test shall be carried out horizontally in the longitudinal direction of the vehicle. The second test sha
21、ll be made at one of the angles specified in5.2. 8.2.4 If the manufacturer of the vehicle agrees to the use of bars for towing the vehicle, all tests shall be repeated as compressive tests. 9 Requirements After each test carried out as specified in clause8, the vehicle shall meet the following requi
22、rements: a) The anchorages shall show no deformation liable to affect normal operation; b) The devices mounted in proximity of the anchorages (for example, compulsory lighting or signalling devices, braking and steering systems) shall show no damage preventing normal operation. 10 Identification The
23、 anchorages shall be identified by the vehicle manufacturer in a suitable manner. 1) In preparation.BS AU 188:1983 ISO5422:1982 BSI 389 Chiswick High Road London W4 4AL BSIBritishStandardsInstitution BSI is the independent national body responsible for preparing BritishStandards.
