Hello All -

Last week, I posted a message requesting information on any
established standards or TLV's (threshold limit values) for
vibration in human subjects for safety purposes.

Below is a summary of the responses.

Thanks very much for all your input,

.. John and Phil

I have seen a listing of such standards, but I can't remember where at the
moment. Perhaps it was in Humanscale from Dreyfus Associates (MIT press).

I would recommend Chapter 10 of the "Handbook of Human Vibration" [Griffin,
1990, Academic Press] as a good place to start. This book runs to almost
1000 pages and provides a comprehensive account of Human vibration. In Ch.
10 Griffin refers to numerous standards from ISO, the British Standards
Institution, and the American National Standards.

However, I should also add that Griffin's summary of Chapter 10 begins "Human
vibration standards are ephemeral."

Let me know if I can be of more help.

The most widely accepted standards (guidelines) for human exposure to
vibration are put out by the International Standard Organization.
ISO 2631 covers whole-body vibration and ISO 5349 covers hand vibration.
ANSI also puts out the identical standards: ANSI S3.18 is the whole-body
satndard. These standards use frequency-weighted filters to determine
the exposure level. Most experts argue that the whole frequency spectrum
must be examined. A good book to look at is "The Handbook of Human
Vibration" by MJ Griffin.

As a starting place, I suggest you see Chapter 12 of Chaffin and
Andersson's book, Occupational Biomechanics. This chapter gives a brief
review of the ISO guidelines on whole body and segmental vibration
exposure.

If you want more detailed expert information, I would suggest you
contact Malcolm Pope (for whole body vibration) or Rob Radwin (for hand/arm
vibration).

You can find information regarding standards for vibration in human
subjects in the 454-page book "Occupational Biomechanics" by Chaffin D.B.
and Andersson G. (J. Wiley & Sons), 1984.

Some information you may obtain in "Human body vibration exposure and its
measurement" by Rasmussen G. (Technical Review, Bruel & Kjaer, 1982 #1)

On of my professors, Rick Gill, has done a lot of Expert witness consulting.
One of the cases he described in our Human Factors in Engineering Design
class involved the full body vibration that 'Skidder' drivers (logging)
experience.

I believe he would be a great source of information for vibration,
especially from the legal point of view.

His email address is: rgill@uidaho.edu

We are actively involved in the measurement of whole-body vibration
and hand-arm vibration in the South African industry. I presume you
want info on whole-body vibration - we measured mining equipment,
trucks, trains, boats, automobiles [but not planes :-)]. There are
two standards we use extensively: BS 6841 (UK) and ISO 2631. The
BS incorporates all of the ISO limits and frequency weigthing, and is
much more comprehensive with regard to limit values for humans. (Our
preferred standard)- They talk of VDV (vibration dose value) which
should not exceed a certain ceiling. The VDV also differ for
vibration when seated, standing, or lying down. The ISO standard
uses another variable (FDPB), but we don't use that very often. The
bottom line: You can't use raw data - it has to be filtered
according to the standards, and then calculations is done to
determine the limit and threshold values. We have implemented all
these in a module that runs with Dadisp.

PS: If you actually want info on hand-arm vibration, you're welcome
to drop me a line.

Regards

Jaco Botes
