Introduction
Food preservation, food hygiene, and food safety are receiving increasing public attention and importance, leading to the growing importance of refrigerated food display cases in the food distribution process.
The role of this section is crucial. GB/T 21001 aims to unify the definition and testing methods for refrigerated display cases in China, and consists of four parts.
composition.
---Part 1.Terminology. This section aims to standardize the terminology and definitions used for refrigerated display cases used in the sale and display of food.
---Part 2.Classification, Requirements, and Test Conditions. The purpose is to standardize the structure, characteristics, and performance requirements of refrigerated display cases, and to unify the manufacturing process.
Requirements for testing conditions, testing methods, classification methods, and grading methods for refrigerated display cases.
---Part 3.Testing and Evaluation. The purpose is to supplement the testing and evaluation methods for the safety and performance of refrigerated display cases.
---Part 4.Classification, Requirements, and Test Conditions for Ice Cream Freezers. The purpose is to clarify and standardize the classification of ice cream freezers.
Requirements and test methods.
Refrigerated display cases are widely used in supermarkets, convenience stores, and other commercial establishments. Their performance and quality directly affect food storage safety and energy efficiency.
Efficiency. This document, as an important component of the refrigerated display case standard system, provides performance testing and quality evaluation guidelines for refrigerated display cases.
Scientific and unified technical standards play a crucial role in regulating market order and promoting technological progress in the industry.
With continuous innovation in refrigeration technology and the market's increasing demands for energy-saving and environmentally friendly performance of refrigerated display cabinets, some parts of the original standard have been revised.
The existing test methods and evaluation indicators are no longer fully adapted to the new demands of industry development. Meanwhile, the International Organization for Standardization (ISO) in this field...
The relevant standards in this field are constantly being updated and improved. In order to keep my country's standards in sync with international advanced levels and promote the development of refrigerated display cases both domestically and internationally...
Fair competition and trade exchanges among products, based on thorough research into the current state of the industry and extensive collection of opinions from all parties, and in conjunction with the development of my country's refrigerated display cabinet industry...
Based on the actual situation and development needs of the industry, the content of the standard has been reviewed and revised. The revised standard further improves the testing...
The accuracy and operability of the evaluation and assessment are improved, with greater emphasis on evaluating the energy-saving and environmental performance of refrigerated display cases, which helps guide enterprises to improve their production capabilities.
To improve product quality and technological level, and promote the healthy development of my country's refrigerated display cabinet industry towards high efficiency, energy saving and environmental protection.
