This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized

E DIN EN 1915-4:2009-06 EN 1915-4:2004+A1:2009 (E) 5 Introduction The aim of this European Standard is to deal with noise as a hazard and to provide methods for the measurement and reduction of noise emission of GSE. A further aim of this European Standard is, de

36、spite the variety of GSE, to obtain representative and comparable information on the noise emissions of this category of equipment. It should be possible to determine and verify this information with justifiable effort. General standards for the determination of the noise emissions at the operators

37、position and of the sound power levels of machines already exist. Because of specific applications these existing standards cannot be applied directly to GSE without supplement of specific machinery and operating conditions as given in this European Standard. The idle condition is included for some

38、machines because it is representative of those conditions in which the GSE has low noise emission as well as waiting between tasks. This European Standard is a Type C standard as stated in !EN ISO 12100“. The machinery concerned and the extent to which hazards, hazardous situations and events are co

39、vered are indi-cated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-visions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and

40、 built according to the provisions of this type C standard. E DIN EN 1915-4:2009-06 EN 1915-4:2004+A1:2009 (E) 6 1 Scope This document deals with noise reduction as a safety requirement. It also specifies the methods for determining the sound pressure level at workstations, other specified positions

41、 and the sound power level of GSE during intended use. The test results are not applicable to the determination of daily exposure to noise for the operator. !This part of EN 1915 is intended to be used in conjunction with the other parts of EN 1915, and with the relevant part of EN 12312.“ 2 Normati

Likewise, components in the fluid systems (such as pumps and relief valves) and mechanical drive systems (gears, brakes, etc.) can add to the total noise emission.
