In recent years there has been a move away from the term Fire Resistance Classification in favor of the term Fire Resistance Rating. The purpose of this proposed revision is to carry that preferred nomenclature forward into the test method. All use of the term classified and its variants have been replaced with the word rating or one of its variants as appropriate. A few instances required additional minor editorial work to make the new term flow with the text and they are identified in the underlined text. The only change being proposed in this ballot item is the shift from classified to rated. No other changes, technical or editorial, are being proposed.
