First of all we know about the national standard is what? Whether this product has a national standard that the airport chair, gb refers to be approved by the competent national standardization, and after the announcement need through formal channels for purchase of files, in addition to the national laws and regulations enforced standard thought, generally speaking, there are some recommendations. But the airport chair are generally will according to the project put forward by the tender documents, or product requirements for production, or will choose manufacturer has some design, this we can is divided into industry standards, local standards and enterprise standards. All I think the airport chair standard can only complex customer requirements, different also don't want to give it a national standard.
