Hello All:

Below you will find the response I received to my post titled
"Friction and anti-slip properties in bath rails" My sincere thanks to
Damien O'Meara for his contribution.

Original Post:
Hello all,

I am working in the technical aids section of the Institute of
Biomechanics of Valencia (Spain). At this moment we are running some
test
with bath and grab rails in order to
assess their performance.

I am interested in knowing about some standarized procedures to test
friction and
sliping properties in the rails. I would apreciate if you could provide
me some info about some standards or bibliography about the topic.

We have designed a test for a circular tube with a foam and a sling.
We apply a preload in A and B as shown on the picture

/O\
| |
A B

Loads A & B are applied with a sling across a foam to the pipe.
The foam is used to simulate the elasticity of the hand skin.
When B begins to move down we score the load that has been added,
and from this measurement we obtain the characterisation of the rail.

I will send a recopilation of the answers.
Thank you in advance,

I am a Phd student from the University of Sydney, Australia.

As part of my PhD (investigation of grabrail design) I have performed 2
studies to assess friction between 5 grabrail materials and palmar skin
under 3 hand conditions. Recently I presented a poster on this topic at

ISB in Zurich.

I have attached a copy of the abstracts from ISB Zurich. You should also

find some references here.

Cheers

His interesting work concerning friction on bath rails has been
published in Ergonomics 2001 (vol 44,11, 973-988).
