ISO 10254:2016 defines the terms relating to air cargo and aircraft ground equipment, as used in the other International Standards in these areas.
NOTE The term "weight" is used throughout ISO 10254:2016 instead of the correct technical term "mass", in order to conform to current commercial usage.
The terms and abridged definitions of ISO 10254:2016 are primarily intended to…
ISO 19252:2008 specifies a method for determining the scratch properties of plastics under defined conditions. The method involves making a scratch by moving a hard instrument (scratch tip) of specified geometry under specified conditions of load and speed across the surface of a test specimen and then assessing the result.
The method is used to investigate the behaviour of specified types of…
Tyre abrasion rate measurement methods — Part 2: Indoor test method by using an abrasion tester on e...
Scope of the proposed deliverable.
This international standard (part 1 or part 2) specifies the method for measuring tread abrasion mass loss of a candidate tyre per unit distance travelled, under loaded conditions, by using vehicles on road (part 1) or an external drum tester (part 2).
Each test method specified in Part 1 and Part 2 measures abrasion performance of a candidate tyre on the…
