• Tên tiếng Anh / Title in English: Mechanical vibration - Hand-held and hand-guided machinery - Principles for evaluation of vibration emission (ISO 20643:2005)
• Phạm vi áp dụng / Scope of standard: This document provides the basis for the drafting of vibration test codes for hand-held and hand-guided powerdriven machinery. It specifies the determination of hand-transmitted vibration emission in terms of frequencyweighted root-mean-square (r.m.s.) acceleration during type testing. For machines where vibration test codes do not exist, it may also be used for determination of emission values and contains sufficient guidance for designing an appropriate test.
