GB/T 22504.3-2018 in English

Background and Significance of Standard Formulation

With the rapid development of my country's grain industry, higher requirements have been put forward for the quality inspection of rice. The formulation of GB/T 22504.3—2018 standard aims to provide a unified auxiliary atlas reference for the sensory inspection of rice to ensure the accuracy and consistency of the inspection results. This standard was proposed by the State Administration of Grain and Material Reserves and was managed by the National Technical Committee for Grain and Oil Standardization, which fully reflects the authority and standardization in the industry.

Implementation Suggestions

To ensure the effective implementation of GB/T 22504.3-2018 standard, it is recommended that:

1. Strengthen the training of inspectors and familiarize them with the basic principles and operation procedures of sensory inspection.
2. Equip with necessary inspection tools, such as magnifying glasses ($3\times$) and other equipment.
3. Establish a database of standard atlases for quick comparison and reference.
4. Develop detailed operating procedures based on actual conditions to ensure the consistency of the inspection process.
