Foreword
This standard replaces GB/T 16577-1996 "Tetrahydroxystilbene polyether polyol."
The main technical differences between standard compared with GB/T 16577-1996 is.
--- Modify the structure and expression of the rule criteria;
--- Revised technical requirements 403,466H products;
--- Increased 405E, 480H products;
--- Product rating from three rating changed to two levels, the product level from "high-class product, first-class products, qualified" to "excellent
Products, qualified ";
Standard Test Method for Determination of hydroxyl value ---, unsaturation and viscosity is increased to "A Method for the Arbitration Act";
--- Inspection rules to delete "batch does not exceed 100t";
--- Inspection rules to add a "bottle for testing, another bottle stored for future reference";
--- Storage of "storage period of six months" to "storage period of one year";
--- Cancellation of the original Appendix A "acid value";
--- Increase the informative Appendix A.
Appendix A of this standard is an informative annex.
