Noise emission label for air compressor and hand held percussive breaker
The Noise Control (Hand Held Percussive Breakers) and (Air Compressors) Regulations (the Regulations) limit noise emission from hand held percussive breakers having a mass of above 10 kg and air compressors capable of supplying compressed air at 500 kPa or above for carrying out construction work. The above equipment must be fitted with noise emission labels when in operation.
How to apply :
Application for a Noise Emission Label should be made in the specific form (Form 1) prescribed under the Noise Control Ordinance and accompanied by:
i) either supporting document showing that the equipment complies with a standard that is substantially the same or more stringent than that set out in the Regulations, such as an EC Declaration of Conformity & relevant documentation under the Directive 2000/14/EC of the European Union; or
a noise testing report certificated by a corporate member of the Hong Kong Institute of Acoustics Limited (HKIOA), a professional member of the Hong Kong Institute of Qualified Environmental Professionals Limited (HKIQEP), or a registered professional engineer in the building services, environmental or mechanical disciplines under the Engineers Registration Ordinance (Cap. 409), certifying compliance of noise emission standards;
ii) trade leaflets/brochures of the particular equipment, if available;
iii) other relevant information such as the manufacturing date of the equipment; and
iv) a prescribed application fee for each label. Cheques, drafts or cashier order shall be made payable to "The Government of the Hong Kong Special Administrative Region" or "The Government of HKSAR" and crossed. The fee payable on submission of the applications will not be refunded.
Applications should be submitted to any of the Customer Service Counters of EPD or via online. For detailed information on the application for the Noise Emission Label, please refer to the Information Sheet on "Control of Noise from Hand Held Percussive Breakers and Air Compressors" published by the EPD.
