Dear Mr. Krueger: In reviewing our response of March 1, 1972, to your letter of Decembe 6, 1971, we have noted that one of our answers contains an error. On page 2, our answer to question 1(b) should read:; >>>'The provisions of S4.3 that you refer to are intended to reflec the performance of samples described in the test procedures of S5. These requirements are intended to provide an exemption for self-extinguishing materials, and not to exempt small samples that are consumed by fire before *one minute* elapses. The standard establishes burn-rate requirements, and manufacturers should keep this in mind in determining whether particular components comply. If your component is such that it is consumed by fire because of its size before the *one-minute* period, then we would expect modifications to the procedure, of a nature described above, to be made in order that a determination of the burn rate of the material is obtained.' (Emphasis added.)<<<; We regret any inconvenience this error may have caused. Yours truly, Richard S. Dyson, Assistant Chief Counsel
