40、EEMUA Publication 140: Noise procedure Specification. All mandatory requirements are included in the Specification document and this Guide is purely illustrative. The Guide is based on the experience of the plant operating companies of the EEMUA membership and although requirements and procedures wi
41、ll vary from plant to plant, the material in this Guide should prove helpful in any case where noise limits have to be set and complied with in the petroleum, petrochemical, power generation and allied industries. The Guide is in three parts: Part 1: Selection of noise limits This is intended primar
42、ily for the Principal1, to give guidance in the selection of noise limits appropriate to any particular locality or requirement. It may be of some value to the Contractor2 in giving an explanation of how the noise limits set for a particular contract are derived. Part 2: Measuring noise from equipme
43、nt Specification EEMUA 140 contains a number of procedures for measuring the sound power levels of equipment and this part gives a general description of how to apply them. It is intended to give guidance to the contractor for ordering equipment and to the equipment vendor3 for providing suitable in
44、formation on his equipment. This edition also recognises the recent advances made in sound power determination using the sound intensity method. The International Organization for Standardization (ISO) has recognised the complementary role of this technique to the more traditional procedures based o
45、n sound pressure measurement. A description of this is provided. Part 3: Noise control in plant design This is intended to be of value to both the principal and the contractor on a project in assisting common understanding in the interpretation and application of the Noise Procedure Specification EE
46、MUA 140 and the noise limits set for the particular project. It gives guidance on the collection and handling of noise data and presents a logical procedure to be followed in design. It includes examples of steps which have to be taken with typical items of plant and draws attention to many points w
47、hich will have to be considered in any plant design. It is not a complete textbook of acoustic design but is a guide to the application of standard acoustic concepts and techniques. 1 The Principal is defined as that party responsible for placing the order for a plant 2 The Contractor is defined as
48、the party which carried out the design, engineering, procurement, construction and commissioning of a plant on an order from the Principal 3 The Equipment Vendor is defined as the party which manufactures or supplies equipment to perform the duties specified by the Contractor EEMUA Publication 141 A

It does not set noise limits because the acceptable limit for any location will depend on factors relevant both to that location and the intended use of the machinery. From the Principals point of view, rather than create blanket noise
