Dear Mr. Lawler: This responds to your recent letter concerning S6.2.4 of Standard No 213, *Child Restraint Systems*. You asked whether section 5.2(d)(1) of Standard No. 209 is the relevant section to be used in testing the release force on buckles used on a child restraint system. The answer is yes.; Section 6.2 of Standard No. 213 sets out the test procedure fo measuring the release force for buckles used in child restraint systems. Section 6.2.4 states that the buckle is to be operated in the manner described in section 5.2(d) of Standard No. 209, Seat Belt Assemblies. S5.2(d)(1) of Standard No. 209 sets out the procedure for measuring the buckle release force. You are correct that S5.2(d)(2) and (3) set out the procedures for conducting several other requirements of Standard No. 209 which do not apply to child restraints and thus are not relevant to the buckle release force test.; If you have any further questions, please let me know. Sincerely, Frank Berndt, Chief Counsel
