Dear Mr. Bingham: This responds to your letter of June 8, 1981, concerning Standard No 209, *Seat Belt Assemblies*. You are correct that my letter of June 1, 1981, on the abrasion test procedure of the standard should have referred to section 5.1(d), instead of to section 5.2(d).; You also suggested that in the process of clarifying the standard' abrasion requirements, the agency should consider possible modifications to sections 4.2(e) and (f) of the standard. In the process of reviewing the abrasion test requirements, the agency will also examine those other sections to determine what changes should be made.; Finally, you raised the issue of whether the standard, as with othe national and international standards, should have a requirement that conditioned webbing must retain a certain percentage of its unconditioned strength and must also meet the minimum strength requirement for unconditioned webbing. The agency is not aware of any data indicating that our current conditioned strength requirements are insufficient.; Sincerely, Frank Berndt, Chief Counsel
