42、nditions 3.1 Testing ranges of chairs and tables If chairs in a range of size marks are all manufactured with the same design details and geometry, it is only necessary to carry out the complete test programme on the highest size mark (including multi-size and height adjustable) in the range, plus a
43、dditional stability tests on the smallest size mark in the range. If tables in a range of size marks are all manufactured with the same design details and geometry, it is only necessary to carry out the complete test programme on the highest size mark in the range. In the event of failure in any of
44、the chairs/tables in the above test programme, it is necessary to carry out the complete test programme on each chair/table size mark individually. 3.2 Testing of height adjustable and multi-size chairs and tables Where tables or chairs can be set to a number of different configurations the worst ca
