Announcements

The Noise Control Law Enforcement Order (Showa 43 Cabinet Order No. 324) and the Vibration Control Law Enforcement Order (Showa 51 Cabinet Order No. 280) have been revised. (Effective from Reiwa 4/12/1)

The performance of air compressors has evolved, but since the standards of the Noise Control Act and the Vibration Control Act have not been revised for a long period of time, the Ministry of the Environment established a “review meeting relating to the review and examination of specific facilities based on the Noise Control Act and the Vibration Control Act,” and as a result of reviewing standards and proceeding with review meetings, regulatory revisions were reported.

Contents of the correction
① Noise Control Law Enforcement Ordinance Appendix Table 1 (2)

After the revision

Air compressors specified by the Minister of the Environment as not generating noise of a magnitude exceeding a certain limit are not subject to regulation as stipulated in Appendix 1 of the Noise Ordinance.
Air compressors (except those designated by the Minister of the Environment as not generating noise exceeding a certain limit, limited to those with a rated motor output of 7.5 kw or more) and blowers (with the exception of those designated by the Minister of the Environment as not generating noise of a magnitude exceeding a certain limit, limited to those with a rated output of 7.5 kW or more.)

② Vibrating Machine Regulation Law Enforcement Ordinance Appendix 1 (2)

After the revision

Compressors specified by the Minister of the Environment as not generating vibrations of a magnitude exceeding a certain limit are not subject to regulation as stipulated in Appendix 1 of the Vibration Ordinance.
Compressors (limited to those with a rated output of 7.5 kW or more, except those designated by the Minister of the Environment as not generating noise exceeding a certain limit)

Mitigation revisions have been reported for air compressors within both noise and vibration regulations. Regulations will be reviewed and examined along with the reduction in noise and vibration of air compressors and the evolution of performance, so please check once again.
