scope:

This European Standard provides specifications for safety, quality and performance requirements for supplementary grip devices, commonly called "SGDs", for type - approved tyres according to the current legislation, intended to be fitted on tyres on vehicles in categories M1, N1, O1, O2 and relevant sub-categories (off road vehicles). The requirements contained in prEN 16662-1 apply to all SGDs, regardless of the material/technology used to build it. In case there are available standards for the specific technology of the device, they are intended to be used in conjunction with prEN 16662-1. In case no standard is available for the specific technology, prEN 16662-1 applies. All tests included within this standard are intended to be performed with activated ABS.
