1 Scope
This standard specifies the location, strength requirements and test methods for safety-belt anchorages, ISOFIX anchorages systems and ISOFIX top tether anchorages intended to ISOFIX child restraint systems for vehicles.
This standard is applicable to anchorages for safety-belts intended for adult occupants of forward-facing or rearward-facing seats in vehicles of Categories M and N.
This standard is also applicable to ISOFIX anchorages systems and ISOFIX top tether anchorages intended to ISOFIX child restraint systems installed in vehicles of Category M1 and N1.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
vehicle type
a category of power-driven vehicles which do not differ in such essential respects as the dimensions, lines and materials of components of the vehicle structure or seat structure to which the belt anchorages and the ISOFIX anchorages systems and ISOFIX top tether anchorages if any are attached and, if the anchorages strength is tested according to the dynamic test, the characteristics of any component of the restraint system, especially the load limiter function, having an influence on the forces applying to the belt anchorages
3.2
belt anchorage
the parts of the vehicle structure or the seat structure or any other part of the vehicle to which the safety-belt assemblies are to be secured
3.3
effective belt anchorage
the point used to determine conventionally, as specified in 4.3, the angle of each part of the safety-belt in relation to the wearer, that is, the point to which a strap would need to be attached to provide the same lie as the intended lie of the belt when worn, and which may or may not be the actual belt anchorage depending on the configuration of the safety-belt hardware at its attachment to the belt anchorage. For example, in the case
——where a strap guide is used on the vehicle structure or on the seat structure, the middle point of the guide at the place where the strap leaves the guide on the belt wearer's side, shall be considered as the effective belt anchorage;
