General requirements for the measurement and evaluation of hand-transmitted vibration in GB/T 14790.1 in. To be able to follow GB/T 14790.1 correct measurements, this section provides practical guidelines and were given hand-transmitted vibration measurements in the workplace Efficiency strategy. This section describes the policy will be applied in practice daily vibration exposure of the operator's workplace and the associated uncertainty. Vibration exposure assessment can be divided into several distinct steps. --- Allowing an operator to identify a series of operations in the normal operating mode; --- Select the operation to be measured; --- Measured for each of the selected operating acceleration root mean square (rms); --- Evaluation of each of the identified actions typical daily exposure time; --- 8h calculated energy such as vibration total value (daily vibration exposure). GB/T 14790.1 described vibration exposure assessment is based on the handle or grip portion of the vibration amplitude measurement and exposure time between. Other factors, such as grip and propulsion force applied by the operator, the arm position, the direction of vibration and environmental conditions, not be taken into consider. As part of the GB/T 14790.1 application does not provide for these other factors evaluation guidelines. However, in general, the report of the whole Ministry of the related information is important for the proposed improved method for evaluating the risk of vibration. Mechanical vibration Human exposure to hand-transmitted vibration measurement and evaluation Part 2. A Practical Guide to Workplace measurements1 ScopeThis section according to GB/T 14790.1 specified in the workplace hand transmitted vibration measurement and evaluation provides guidance. This section GB/T 14790 describes the calculation 8h energy such as vibration total value (daily vibration exposure) conducted a representative vibration measurements Measures to determine the amount of each operating day and time of exposure should be taken. This section provides methods for determining relevant in the evaluation of vibration exposure should consider The method of operation. This section applies to human exposure to (bear) mounted hand-held or hand-guided machinery, vibration of the workpiece, a mobile or stationary machines controlled by Set to pass all occasions arm system vibration.2 Normative referencesThe following documents for the application of this document is essential.
