1. The standard overall level is not high

In the standard system construction, standards development principles and methods, and technical content, there is a big gap between international standards and industrial developed countries and regional standards. There is a certain gap between the standard technical content indicators and foreign advanced standards. The international standardization work on product safety performance, environmental protection indicators, resource conservation and comprehensive utilization has not been thoroughly studied. At present, a complete set of vibrating screen industry that is in line with national conditions and can be in line with international standards has not yet been fully formed. standard system.

2. The standard content is biased towards production and it is difficult to meet market needs. with the development of economy.

The market is increasingly demanding standardization work. The government's macro management needs standards; the products of enterprises need to enter the market; the users also need to use standards to protect their economic interests and legitimate rights and interests. The required standard is the basis for determining whether the product is qualified, performing product quality certification, and signing a product order contract. The current standards focus on the manufacturing requirements, materials, and process requirements of the production process. Neglected trade requirements such as delivery acceptance conditions, safety performance, and reliability.

3. There are repeated cross-restraints in the standard.

Duplication and intersection between industry standards and industry standards are currently occurring. This has caused the coexistence of multiple industry standards for the same product in the screening machinery industry, the inconsistency of standard attribute classification, and the different standard requirements, which bring unnecessary troubles to the implementation, supervision, management and use of the standard.

4. The naming of screening machinery products is not standardized, and there is no uniform executable standard.

Each manufacturer names the product according to its own needs. As a result, the compatibility between the products of the vibrating screen manufacturers is poor. From the perspective of long-term interests, it is not conducive to the development of the entire industry, and even restricts the development of the entire screening industry, and becomes a stumbling block on the development of the industry.
