Foreword

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 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 matters of

electrotechnical standardization.

Introduction

This International Standard has been developed in response to demand throughout the world, and the

aim has been to ensure that luggage carrier manufactured in compliance with it will be as safe as is

practically possible. The tests have been designed to ensure the strength and durability of the luggage

carrier, demanding high quality throughout and consideration of safety aspects from the design stage

onwards.

The scope has been limited to safety considerations and has specifically avoided standardization of

components.

4 This International Standard specifies safety and performance requirements for the design and testing of

5 both non cycle specific luggage carriers intended for mounting (with or without tools) and cycle specific

6 luggage carriers mounted on complete cycles. It applies to luggage carriers intended to be positioned

7 above and adjacent to the wheels of cycles. This standard lays down guidelines for instructions on the use

8 and care of such luggage carriers.

9 This International Standard does not apply to removable luggage (for example, handlebar bags or baskets

10 that are not permanently attached).

113 The fatigue tests shall be done on the same sample and fasteners. Others tests can be conducted on a new

114 test sample, but if only one test sample is available, it is permissible to conduct all of the tests on the same

116 When more than one test is conducted on the same sample, the test sequence shall be clearly recorded in

117 the test report or record of testing.

118 If the luggage carrier is made of plastics or metal and plastics, it shall be submitted to the tests in 5.13

119 after being tested according to 5.9, 5.10, 5.11 and 5.12.

120 In the strength tests, all components shall be in the fully-finished condition.

121 The luggage carrier shall be tested using the connecting interface position(s) and type(s) according to the

122 luggage carrier manufacturer's specifications.

123 When more than one mounting configuration is used the conditions that provide the luggage carrier with

124 the most and least movement shall be tested.

125 The luggage carrier shall be tested with all accessories provided (e.g. lock, pumps, etc.).

126 For luggage carrier intended to be fitted on an EPAC and designed to include a battery, the test shall be

127 performed with the maximum battery load [see 7 q)] in addition to the mass defined in Clause 4.

128 For permanently attached luggage carrier, all clauses apply except 5.8 and 5.13.

129 For maximum load capacity under 27 kg, the mark shall warn the user that the product is not suitable for

130 the transportation of a child seat. See Figure 11.
131 5.2 Tolerances

132 Unless stated otherwise, accuracy tolerances based on the nominal values shall be as follows.

133 Forces and torques 0/+5 %
134 Masses and weights ±1 %
135 Dimensions ±1 mm
136 Angles ±1°
137 Time duration ±5 s
138 Temperatures ±2 °C
139 Pressures ±5 %
140 Frequencies and linear stroke ±5 %
141 5.3 Crack detection methods

142 Standardized methods may be used to emphasize the presence of cracks where visible cracks are

143 specified as criteria of failure in tests specified in this International Standard.

144 NOTE For example, suitable dye-penetrant methods are specified in ISO 3452-1, ISO 3452-2, ISO 3452-3 and

[2][3][4][5]
145 ISO 3452-4.
146 5.4 Sharp edges

147 Exposed edges that could come into contact with the rider's or a transported person’s hands, legs, etc.,

148 during normal riding or normal handling and normal maintenance shall be neither sharp nor designed

149 such that injuries can arise when the bicycle is used correctly. Spring ends shall be rounded or fitted with

150 protective caps.
151 5.5 Security of safety-related fasteners
152 5.5.1 Security of screws

153 Any screws used in the internal assembly of the luggage carrier shall be provided with suitable locking

154 devices, for example, lock-washers, lock-nuts or stiff nuts.

155 5.5.2 Minimum breaking torque

156 The minimum breaking torque of screws for the fastening of the luggage carrier to the cycle shall be at

157 least 20 % greater than the manufacturer's recommended tightening torque.
[1]

158 NOTE For example, mechanical and physical properties of bolts are specified in ISO 898-1.

159 5.6 Minimum requirements for rear luggage carriers to which a child seat could be

160 attached

161 Rear luggage carriers to which a child seat could be attached shall have a luggage carrier platform width

162 of 175 mm maximum except for luggage carriers using a manufacturer-specific child seat mounting

163 system. And the maximum load capacity of the rear luggage carrier shall be at least 27 kg.

164 Note Some child seats may have other additional attaching requirements.
165 5.7 Protrusions

166 This requirement is intended to address the hazards associated with the users of bicycles falling on

167 projections or rigid components on a bicycle, possibly causing internal injury or skin puncture.

168 A screw thread that is an exposed protrusion shall be limited to a protrusion length of one major diameter

169 of the screw beyond the internally threaded mating part.
170 5.8 Rear luggage carriers — Provision for lighting

171 The rear aspect of any rear luggage carrier not equipped with an integral rear lamp and reflector can be

172 equipped with a bracket or brackets, either as an integral part or separate accessory (or accessories) to

173 allow the fitting of a rear lamp and reflector.

174 When this requirement is satisfied by the provision of separate accessories, these accessories should be

175 included when the luggage carrier is sold.
176 5.9 Dynamic load tests
177 5.9.1 Requirement

178 When tested by the methods described in 5.9.2, 5.9.3, 5.9.4 and 5.9.5, there shall be no fractures or visible

179 cracks in any part of the luggage carrier and the specifically designed mounting points of the luggage

180 carrier.
181 5.9.2 General loading method

182 The mounting method for the dynamic load test of cycle specific luggage carriers and non cycle specific

183 luggage carriers differ. The mounting requirement are given in Annex A.
184 Attach a mass equal to the maximum load capacity stated by the manufacturer.

185 The specified weight (maximum load capacity given by the manufacturer) shall be applied in the middle

186 of the platform = L / 2 and W / 2 this is illustrated in Figure 1. Tolerance ±5 mm on the position of the

187 weight. The clamping shall not deform the tube or the platform:

188 — For luggage carriers with a platform, a weight or weights shall be evenly distributed on more

189 than 70 % area of the top surface of the luggage carrier platform;

190 — The centre of mass of this weight shall coincide with this position and also lie within h = 40 mm

191 of the centreline of the top of the platform;

192 — Side bags can be filled with the balls of which 40 mm ± 0,5 mm diameter and 24 g ± 1 g weight

193 (example squash balls) until reaching the load capacity, other dimension and weight can be used

194 to obtain a good matching between weight and volume. The weight shall be evenly distributed;
