Textile Machinery Noise Test Specification Series National Standards Promulgated (Continued)
3. There are only three terms and definitions in the chapter "terminology and definitions". To facilitate the understanding of standard users, we try to list the acoustic terms appearing in the new standard, and define the relevant noise basic standards. Therefore, there are 13 terms in g / T, 7, 11, 1 - 200.
4. Appendix B of "g / T / T", "the sound power level of textile machinery noise and the test of the sound pressure level at the specified location" are compiled according to the contents of the appendix A of the S90 90 2 - 1, 2000. The main technical contents are not deleted, but according to the requirements of the Compilation Rules of our national standard (g / T 1. 1 - 2000), the editing is carried out. Since the appendix is a reference appendix, the test report can be made in tabular form according to the purpose of noise test when used in specific circumstances.
In the past, when we adopted international standards, we had always focused on the national conditions. What we could not do would not be adopted or amended. After joining the W TO, we will act according to international rules. Unless we consider the factors such as geography, climate or environmental protection and health and safety protection, we should try to be equivalent to adopting international standards. At the same time, we should strengthen the consciousness of participating in the international standard setting work and change the passive bid to take the initiative to mark the bid.
The new standard is rich in content, measuring methods and ways. Our working group has done some experimental work in order to study the applicability of various methods. The Secretariat of the National Textile Machinery Standards Committee intends to publicize the new standards in early 2003, and hopes that all enterprises and enterprises will participate actively in order to correctly use the new standards.
Noise is not only harmful to human health, but also abnormal noise. Therefore, textile machinery enterprises should invest funds properly, purchase instruments, test and analyze the noise, and improve the overall level of textile machinery.
