Foreword

GB/T 4618 "Plastics - Determination of chlorine content epoxy resin" is divided into three parts. --- Part 1. Inorganic chlorine; --- Part 2. Easily saponifiable chlorine; --- Part 3. Total chlorine. This section GB/T 4618 Part 1, identical with ISO 21627-1.2002 "Plastics --- --- chlorine content of an epoxy resin Determination --- Part 1. Inorganic chlorine "(in English). This section is equivalent translation ISO 21627-1.2002, identical in technical content. For ease of use, this section do the following Edit modifications. a) The "ISO 21627.2002 in this part" to "GB/T 4618 this part" or "this part"; b) Delete the ISO 21627-1.2002 Foreword; c) increase the foreword to the national standard of this Part; d) For ISO 21627-1.2002 and other international standards referenced in our country is equivalent to using the standard, this section with a quote me National Standards corresponding to international standards in place, the rest is not tantamount to the adoption of a standard international standards in this section are Referred to directly; e) use of decimal notation. "" instead of the international standard decimal symbol "." f) the precision of the relevant Chapter 9 content into information appendix NA "ISO 21627-1.2002 precision" in. This Part replaces GB/T 4613-1984 "resins and glycidyl esters - Determination of inorganic chlorine." Section compared with GB/T 4613-1984 The main changes are as follows. --- Change the standard name, increasing the foreword; --- Increasing the normative references; --- Increasing the terms and definitions; --- Reagent butanone replaced by acetone; --- Standard solution 0.002mol/L 0.01N silver nitrate solution consisting of isopropyl alcohol or an aqueous solution of silver nitrate into 0.002N; --- Reference reagent sodium sulfate into a temperature from 120 ℃ 500 ℃ ~ 600 ℃; --- Sample weight change by the 3g ~ 10g 10g; --- Increase the finish explaining the determination; --- Increased requirements result of rounding. Appendix NA This section is informative appendix. This part is proposed by the China Petroleum and Chemical Industry Association.
