Assemble a test-bar to the stem, and apply a force of 1 000 N at a distance of 300 mmfrom the axis of the stem as shown in Figure 18. Maintain this force for 1 min.4.7.6.2 Handlebar and stem assembly – lateral bending test4.7.6.2.1 GeneralThis test is for manufacturers who produce handlebars and stems or for cycle manufacturers.4.7.6.2.2 RequirementWhen tested by the method described in 4.7.6.2.3, there shall be no cracking or fracture of the handlebar, stem orclamp-bolt and the permanent set measured at the point of application of the test force shall not exceed 15 mm.36
