19、 object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this standard is to define a standard test method to a

23、rrel as described in Clause 5. During a test not more than one sample shall be present in the barrel. The barrel turns at a rate of approximately 5 rev/min. The total number of revolutions (the number of falls is twice the number of revolutions) shall be according to the detail specification. NOTE (

24、Detail) specifications may define different numbers of revolutions for specimens with a different mass. 5 Test equipment The specimen shall be tested in a tumbling barrel as shown in Figure 1. Where a large number of specimens has to be tested, the barrel may contain a number of sections, one specim

25、en being placed in each section, so that simultaneous testing may be carried out. BS EN 60512-7-1:201060512-7-1 IEC:2010 5 The width of each section, W, is not specified but should preferably be between 200 mm and 300 mm, depending on the size of the specimen. Each compartment in which the specimen

26、rests between falls is backed by a wedge-shaped piece made of chip resistant rubber with a hardness of 80 20 IRHD, as defined in ISO 48, and the sliding surfaces of that same compartment are made of smooth, hard plastics laminated sheet. The rotating barrel is designed so that the shaft does not pro

27、trude into the interior. The rotating barrel is provided with an aperture with a lid which may be made of transparent acrylic material.
