Foreword

The revised standard Japanese standard JISK2437-1994 "phenols" (phenol, cresol and cresol acid, xylene acid) in xylenol Acid Standard (Japanese version). This standard uses JISK2437-1994 time, made some changes to the relevant technical differences incorporated into the body, these techniques are given below Surgery difference. Appendix A gives a list of structural differences, for reference. --- Remove the Japanese standard and the proportion of hydrogen sulfide content; --- Density and moisture measurement using a national standard methods, and increase the moisture content measured arbitration (this standard 4.2 and 4.3); --- Phenolic component gas chromatography column by the packed column is amended as capillary column measuring method according to the GB (this standard 4.5); --- Specimen and preparation method used GB (5.2 of this standard); --- Increased rounding off the contents (of the standard 5.3); --- Increased security precautions contents (Chapter 7 of this standard). This standard replaces GB/T 2600-1997 "Industrial xylenol." This standard compared with GB/T 2600-1997, the main changes are as follows. --- Modify the standard name; --- Index with content instead of distillation test indicators; --- Neutral oil index is amended as neutral oil test (turbidity method); --- Increasing the Tank Container Transport and labeling requirements for dangerous content. Appendix A of this standard is an informative annex. The standard proposed by China Iron and Steel Association.
