Introduction

The automatic titration analyzer can be used to determine the fatty acid value, acid value and acidity, and peroxide value in grain and oil products and their products. This standard is used to test and evaluate the basic performance of automatic titration analyzer accuracy, precision, inter-station difference, stability, safety and so on. Grain and oil testing equipment Automatic titration analyzer technical conditions and test methods

1 Scope

This standard specifies the technical requirements, test methods, inspection rules, product signs, product certification, instructions for use of the automatic titration analyzer. Book, packaging, transportation and storage. This standard applies to the use of image analysis technology or other sensor technology to the fatty acid value, acid value and acidity of grain and oil and its products. The oxidation value is used as an automatic titration analyzer (hereinafter referred to as a titrator).
