ECE Regulation 16/04 "Safety Belts", with text not applicable in Australia struck through. The text has been modified slightly, to make it clear that it only applies to 'Type 4N Retractors'.

6.2.5.3 Emergency locking retractors 'TYPE 4N RETRACTORS'

6.2.5.3.1 A n emergency locking 'Type 4N Retractor', when tested in accordance with paragraph 7.6.2 must satisfy the conditions below:

4.6.2.5.3.1 FOR AUSTRALIA WHERE A VEHICLE CATEGORY IS REQUIRED, OR A  MANUFACTURER ELECTS, TO COMPLY WITH  CLAUSES 5.1.1 OR 5.1.2 WHICH INVOKE DYNAMIC TESTING, THE REQUIREMENTS OF CLAUSE 10 MUST BE COMPLIED WITH.

6.2.5.3.1.1 The locking must have occurred when the deceleration of the vehicle reaches 0.45 in the case of type 4 and 0.85 g[1] in the case of 'Type 4N Retractors'.

6.2.5.3.1.2 It must not lock for values of acceleration of the strap measured in the direction of the extraction of the strap of less than 0.8 g in the case of type 4 or less than 1.0 g1  in the case of 'Type 4N Retractors'.

6.2.5.3.1.3 It must not lock when its sensing device is tilted 12o or less in any direction from the installation position specified by its manufacturer.

6.2.5.3.1.4 It must lock when its sensing device is tilted by more than 27o in the case of type 4 or 40o in the case of 'Type 4N Retractors' in any direction from the installation position specified by its manufacturer.

6.2.5.3.1.5 In cases where the operation of a retractor depends on an external signal or power source, the design must ensure that the retractor locks automatically upon failure or interruption of that signal or power source.

6.2.5.3.2 A retractor with multiple sensitivity must satisfy the specification above, when tested in accordance with paragraph 7.6.2.  In addition if one of the sensitivities relates to strap extraction, locking must have occurred at a strap acceleration equal to or more than 1.5 g in the case of type 4 or more than 2.0 g1  in the case of 'Type 4N Retractors', when measured along the line of the extraction of the strap.

6.2.5.3.3 In the case of the tests mentioned in paragraphs 6.2.5.3.1 and 6.2.5.3.2 above the amount of strap movement which may occur before the retractor locks must not exceed 50 mm starting at the length given in paragraph 7.6.2.1. In the case of the test mentioned in paragraph 6.2.5.3.1.2 above locking must not occur during the 50 mm of strap movement starting at the length given in paragraph 7.6.2.1.

6.2.5.3.4 If the retractor is part of a lap belt, the retracting force of the strap must be not less than 0.7 daN when measured in the free length between the dummy and the retractor in accordance with paragraph 7.6.4.  If
