Reduced comfort boundary and evaluation criteria for human expoure to whole-body vibration

This standard specifies the limits and evaluation criteria of vibration parameters for maintaining human comfort when the human body is exposed to whole-body vibration. This standard applies to the whole-body vibration environment of the human body generated by various vehicles or machinery, and is used to evaluate the impact of various operating vibration environments on personnel comfort; and can be used as a basis for designing various devices or facilities, evaluating their performance or taking vibration control measures. This standard applies to periodic vibration, random vibration or non-periodic vibration with a distributed spectrum in the frequency range of 1~80Hz. It is also applicable to continuous impact vibration whose energy is within this frequency band. This standard applies to vibration with a peak factor of no more than 3, or vibration with a peak factor of the weighted signal of no more than 6. This standard is only applicable to normal and healthy people. Generally refers to people who can engage in normal daily life, including travel, and can withstand typical work shifts or shift work loads. This standard applies to people who are subjected to vibration in a standing or sitting position through the main support surface, and also to people in a lying position and a reclining position.

This standard is only applicable to normal and healthy people. Generally refers to people who can engage in normal daily life, including travel, and can withstand typical work shifts or shift work loads. This standard applies to people in a standing or sitting position with vibrations applied to their primary support surface, and also applies to people in a lying or reclining position.
