Foreword

Test 2000 "Plastics polyester resins, paints and varnishes --- partial acid value and total acid value. This standard is identical with ISO 2114 Fixed "(in English). This standard replaces GB/T 6743-1986 "Paints and varnishes - Determination of acid value." This standard and GB/T 6743-1986 main technical differences are as follows. --- Front line version is equivalent to using ISO 3682. 1983, and this is equivalent to using the standard ISO 2114.2000. ISO 2114.2000 by the ISO 2114.1996 and ISO 3682.1996 revision merge together; --- Increasing the scope of a polyester resin; --- The acid value is divided into partial acid value and total acid value; --- Increasing the total acid assay (method B); Sampling of change when --- acid value measurement; --- Potentiometric titration acid number measured to the turning point of the titration curve as the end point of titration, GB/T 6743-1986 to pH = 7 As titration end; --- Either acid value is calculated on resin solids, the dilution may be calculated acid value of the resin; --- Precision data in more detail, in particular; --- Increasing the concentration of potassium hydroxide standard solution calibration method (Appendix A). Appendix A of this standard is an informative annex. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee paint pigment (SAC/TC5) centralized. This standard was drafted. CNOOC Changzhou coating Chemical Research Institute.
