It is well appreciated that friction and wear are interrelated subjects simply because friction is involved in wear mechanisms. Indeed, both friction and wear can be studied and measured in the same experiment and this is done in, for example, the investigation of bearings and sliding joints. Friction plays its part in rubber wear mechanisms and needs to be considered when these mechanisms are being studied. Furthermore, with a major rubber product, tyres, friction (resistance to slip) and wear are two of the most important performance parameters. However, when it comes to laboratory measurements on rubber the two tests are generally considered as separate subjects and historically have not been accredited equal status. Whereas friction tests have rarely been standardised and are carried out in relatively few laboratories, dozens of wear or abrasion tests have been developed, quite a few have been standardized and abrasion apparatus is relatively common in rubber laboratories. It can be argued that this situation is not unreasonable, as far more than simply friction is involved in rubber wear processes and wear is probably seen to be directly a problem in more applications of rubber than is friction. On the other hand, the role of friction in slipping accidents and in sports activities has assumed huge importance over the last couple of decades. This has resulted in a large amount of testing and test method development which is relevant to rubbers in flooring and footwear.
