This tentative standard, which complies in part with document ISO/T C 94/SC 2/l 88* is being issued pending the completion of ISO work on retractors.
Retractors (with or without slip-through attachment devices) covered by this standard are to be incorporated into the seat belts specified in Swedish standard SIS 88 28 51 .
Consequently, a complete seat belt assembly including a retrartor must be used in order to fully evaluate the retractor.
The symbol g which appears in this standard represents the constant quantity of the standard acceleration of free fall. g -9. 81 m/S2
