Foreword

This revised standard adopts ASTMD777-97 (2002) "performance test methods and flame-retardant paper standard cardboard burning" (in English). test Into account China's national conditions, the use ASTMD777-97 (2002), the present standard do some modifications. About the technical differences have been incorporated into the text and identifies a single vertical line in which they are involved with the provisions margin. The standard lists the reg number in Appendix A and ASTMD777-97 (2002) List of control clauses numbered. We give a list of these technical differences and their reasons in Appendix B
