Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard EN12053.2001 A1.2008 "Safety of industrial vehicle noise emissions measurement methods," the technical content completely Consistent. Correspondence between the consistency of the standards of international documents and normative references of the following documents. --- Determination of sound power levels of noise sources reflecting plane free field engineering method GB/T 3767-1996 Acoustics sound pressure (ISO 3744.1994); --- Declaration and verification of GB/T 14574-2000 Acoustics machinery and equipment noise emission values \u200b\u200b(ISO 4871.1996). This standard made the following editorial changes. --- Remove the EN12053.2001 A1.2008 in relation to the introduction of harmonized standards and EU directives; --- Remove the EN12053.2001 A1.2008 Annex ZA (informative) and Annex ZB (informative). The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee Vehicle (SAC/TC332) centralized. This standard is drafted by. Anhui Heli Co., Ltd., Beijing Materials Handling Design and Research Institute. Participated in the drafting of this standard. Guangxi Liugong Machinery Co., Ltd., Zhejiang Connaught Machinery Co., Ltd., Xiamen, Xiamen Engineering Machinery Unit Limited copies. The main drafters of this standard.

Introduction

This standard is a type C standard GB/T 15706.1 stipulated. The standard range indicated in the dangerous contents covered. In addition, industrial vehicles should be consistent with GB/T 15706.1 About This standard does not Han Provisions cover a variety of dangerous situations. Common Criteria vehicle noise emissions and sound power level measured at the operator position already exists, but for some special applications, these Standard not be directly applied industrial vehicles. Therefore the drafting of this standard is necessary. The basic standards ISO 3744.1994 and ISO 11201. 1995 has been cited in this standard. The standard deeper purpose is. no matter what type of industrial vehicles, and the like are available to typical noise emission of information. This information should be measured and verified. This requires defining the working conditions and the typical time characteristics. Industrial vehicles idle condition (IDLE) is included, because. The state is the state of the vehicle is typically a low noise emissions, lower vehicle Noise radiation conditions including drops, tilt, load handling, slow motion and two operations wait. Evaluation of sound power levels commonly used assay envelope surface, in the vehicle running state with six or more microphones measuring point, have the When the big technical difficulty. Then a large number of comparison can be found, with the recommended four microphones spotting method to obtain the final result Results with six or more microphones measuring points obtained in the deviation value is very small, so the recommended four microphones spotting Party Method is feasible. However, the test results do not apply to the noise at the operator position. Measurement of noise radiation safety of industrial vehicles

1 Scope

This standard specifies the industrial vehicles (including off-road vehicle) measurement operator position sound pressure level and sound power level. Type tests specified in this standard apply to all listed in Table A.1 industrial vehicles. According to the test results of this standard test, the vehicle can also be used to assess the degree of harm to the industrial noise released.
