Brief introduction of new national standard
Synthetic material surface course playground for primary and secondary schools (gb36246-2018). It is the first compulsory new national standard issued by us at present. Due to its mandatory, new standards, strict requirements and wide coverage, it is bound to bring great impact and change to the sports flooring industry.
There are four points for analysis
01. Mandatory
New standard
03. Strict requirements
04. Wide coverage

What is mandatory
GB (national standard) refers to the national standard approved by the national standardization authority to protect human health, personal and property safety, and enforced by laws and administrative regulations. The national standards are mainly divided into mandatory national standards (GB) and recommended national standards (GB / T)
Recommendatory standards, also known as non compulsory standards or voluntary standards, refer to national standards or industry standards that manufacturers and users are not forced to adopt, but are encouraged to adopt voluntarily by economic means or market regulation.
Compulsory national standards are the standards to protect human health, personal and property safety and the national standards to be enforced by laws and administrative regulations. It is the state's explicit requirement in the form of law that the technical contents and requirements specified in some standards must be implemented, and it is not allowed to violate or change them for any reason or in any way.
Therefore, the current national standard GB / T 14833-2011 will be slightly insufficient. The new national standard GB 36246-2018 is a compulsory national standard, so it is of great significance to standardize the industry environment, optimize the industrial structure, and enhance the competitiveness of high-quality enterprises. It is also the reason why it can become the first year standard point of runway quality.

——————————————————————————————————————————— How to embody strict requirements?
Strict requirements will force the flooring industry to upgrade in an all-round way
As a result, the products on the market began to change to water-based or solvent-free
The new national standard involves many projects
Raw materials, granules
For the first time, the runway raw materials are specified in detail
Stadium materials
The detailed standard requirements of ground materials are formulated
plastic track
The physical and chemical properties of the runway were optimized
Detection means
Update and add a variety of detection methods to eliminate hidden dangers
To be continued
The new national standard will be officially implemented in November. As the drafting unit of the new national standard, Jierui will devote itself to focusing on the push of the new national standard series to facilitate your docking with the new national standard.
