Foreword

GB/T 24148 "plastic unsaturated polyester resins (UP-R)" is divided into the following nine sections.

--- Part 1. Designation system;

--- Part 2. Sample preparation and performance measurement;

--- Part 3. Technical requirements;

--- Part 4. Determination of viscosity;

--- Part 5. Determination of solid content;

--- Part 6. 130 °C reactivity was measured;

--- Part 7. Determination of gel time at ambient temperature;

--- Part 8. platinum-cobalt colorimetry color;

--- Part 9. Total volume shrinkage rate determination.

This section GB/T 24148 Part 1, identical with ISO 3672-1:2000 "Plastics - Unsaturated polyester resins (UP-R) - Part 1. naming "(in English), for ease of use, this section made the following editorial changes.

--- The "this International Standard" by "this section", the "ISO 3672 of this part" to "this Part";

--- Remove the ISO 3672-1:2000 Foreword;

--- Increase the national standard foreword;

--- The "Normative References" section listed with the corresponding international standard in place of national standards;

--- Use of decimal symbol instead of the international standard decimal symbol ",". ",";

--- According to our country, delete the contents of 1.5.

1 Scope

1.1 GB/T 24148 This part of the establishment of a group with a character named unsaturated polyester resins (UP-R) system.

1.2 In accordance with the parameters of the base polymer, filler/reinforcing material (type and content), a predetermined processing method, and the required performance for naming Classification of performance characteristics to distinguish different types of UP-R.

1.3 section applies to generic liquid and solid unsaturated polyester resin.

1.4 Naming of the same material do not necessarily have the same performance. This section does not provide specific materials specific application and/or processing methods may be required Data engineering data, performance data or processing conditions. If such additional properties, it should be in accordance with the provisions of Part 2 of this section Standard Test Method for Determination of these properties.
