39、tation of children and luggage. 4.2 Sampling A single trailer shall be subjected to all of the following tests. For all cycle trailers, where the superstructures have a variable design, all combinations of equipment shall meet all relevant requirements. Accessories shall, if included by the manufact
40、urer, be included in the tests. In cases where the test method allows an element of discretion on the part of the tester, the tester shall use his discretion to produce a situation which he considers most likely to result in a failure. 4.3 Order of tests The tests shall be performed in the following
41、 order: a) inspection test; b) dynamic test; c) static test. For the order of tests, see Annex C. 4.4 Tolerances Unless stated otherwise, the tolerances given in Table 2 shall apply to nominal values.

Use the test arm and test leg fixed at the shoulder and at the thigh of the test body and determine which parts of the cycle trailer can be touched (see Figure 1). For the dimensions of the test arms and
44、test legs, see Table A.1. No two parts of a test limb shall be bent more acutely than 90. No part of the test leg shall pass behind a vertical plane through points B. Use all available seating positions. Figure 1 Determining the extent of the access zone 5 Materials 5.1 Chemical properties for type
