New Regulations for Noise Limits in Open Presses: An Overview
Introduction
As the manufacturing industry continues to evolve, concerns about environmental sustainability and worker well-being have become increasingly important. One area where regulations have been put in place to address these concerns is in the noise levels of open presses, which are used in various industries, including forging, manufacturing, and more. The State Machine Industry Office has recently approved new regulations for noise limits in open presses, which come into effect from January 1, 2000. In this blog post, we’ll delve into the details of these regulations and discuss what they mean for manufacturers.
Preface
The new standard, GB/T 3623-2000, is a revision of the 1987 standard, ZB J62 006.2-87, "Noise Limit for the Forging of Open Machines Open Noise". This standard is designed to provide a more accurate and comprehensive approach to measuring the noise levels of open presses, taking into account the latest technology and regulations.
Noise Limits
The new standard sets out two types of noise limits: noise A and noise pressure level. Noise A refers to the sound power level, which is measured in decibels (dB). The noise pressure level, on the other hand, is the level of noise that is perceived by the human ear, also measured in decibels.
According to the new standard, the noise A and noise pressure level of the sound power level of the press during the operation of the continuous air should not be greater than the provisions of Table 1. This table sets out specific limits for different levels of nominal power.
Table 1: Noise Limits for Sound Power Level
| Nominal Power (Kn) | L<sub(A) (dB) |
|---|---|
| ≤31.5 | 70 |
| 31.5-63 | 80 |
| 63-160 | 80 |
| 160-250 | 90 |
| 250-630 | 95 |
| > 630 | 100 |
For example, for a press with a nominal power of 50 kW, the noise A level should be no higher than 80 dB.
Implications for Manufacturers
The new standard will have a significant impact on manufacturers who use open presses in their production processes. To ensure compliance with the regulations, manufacturers will need to monitor and record the noise levels of their presses and take steps to reduce noise levels if they exceed the set limits.
Conclusion
The new regulations for noise limits in open presses are an important step towards creating a safer and more sustainable manufacturing environment. By understanding the new standards and taking measures to comply, manufacturers can ensure that they are not only meeting regulatory requirements but also protecting the well-being of their employees and the environment.
