This standard made the following editorial changes.

--- The Chapter 12 "EN number" replaced by "standard number";

--- The example Chapter 12 "Noise Measurement EN13023H.2.2-2 level" to "noise measurement GB/T 28386H.2.2-2 class";

--- Increase the number of tables in the appendix.

--- Original Appendix J to Appendix I, so that the number of Appendices according to the English alphabetical order continuous arrangement;

--- Removed BSEN13023:2003 The informative annex ZA "the basic requirements of European standards or other provisions of EU directives." the standard proposed by China Machinery Industry Federation.

This standard by the National Printing Machinery Standardization Technical Committee (SAC/TC192) centralized.

1 Scope

This standard specifies the conditions under specified measurement measuring, marking, verification print GB/T 28387 involved, and paper processing machinery Paper, binding air noise emission values \u200b\u200bof machinery finishing requirements EN1034 involved; this also provides noise measurement criteria used Method and installation and operating conditions of the test.

This standard applies to the mechanical (for example. machines and machine parts are listed in Appendix A ~ Appendix I) Determination of noise emission, standard Display and verification. Test report recommended that all arrangements with the assembly, installation and operating conditions and work-related position measuring noise when recording information.

Noise emission values \u200b\u200bare sound power level LW emission sound pressure level LP and machines working position.

Note 1. The sound power level value reflects the noise level of the machine; emission sound pressure level reflects the impact of labor environment.

Note 2. The noise emission values \u200b\u200bof machinery and equipment can be labeled and used printing machinery and paper processing corresponding noise emission values \u200b\u200bof machinery on the market for comparison.

Noise measurement methods specified in this standard, including engineering method (accuracy class 2) and the barrel Trade Law (accuracy level 3). Use of this standard noise Determination of acoustic emission values \u200b\u200bwill ensure that its reproducibility within a specific range. These range from the precision level of noise measurement method used to determine.

Position measurements and other emission sound pressure level specified by the position based on the standard (ENISO 11200:1995, ENISO 11202.

1995, ENISO 11203:1995 and ENISO 11204:1995) to establish, sound power level measured by the basic standards (ENISO 3740.

2000, ENISO 3744:1995, ENISO 3746:1995, ENISO 9614-1:1995 and ENISO 9614-2:1996) to establish.
