Shore A Durometer Scale Shore Hardness Rubber Shore A Scale Shore
Durometer Test Stand
1.Instruction
Shore Durometer Test Stand is R&D for our shore durometer which
can make test more stable and accurate. The weight causes measuring
force, pressing the tip of durometer onto tested material, so as to
obtain a more stable and accurate hardness value. The weight is
selected according to the installed Shore Durometer. These Test
Stand is applied for A Shore Durometer, D Shore Durometer, AO Shore
Durometer, AM Shore Durometer, C Shore Durometer
2.Operation
Fix Shore durometer on the test stand through installation pole.
Put hardness block in accessory on glass stage. Press down handle,
under weight of poise, durometer tip goes into hole of the block
till press foot of durometer touching block completely. At this
time, the hardness value on display should be within ±1 of signed
value on the block. If the value is out of ±1,please turn the
adjusting nut under glass stage to make value within to ±1. If the
durometer is without hardness block, press down handle, under
weight of poise, durometer foot attach to glass stage completely.
At this time, the hardness value on display should be within 100
±1, if it is not, please turn the adjusting nut under glass stage
to make value to 100 ±1. Put the test material on the glass stage,
drive operation handle. Under weight of designation weight,
durometer attach to test material completely, read the value showed
on display in regular time.
Reading value time of thermoplastic rubber is 15 seconds, for
vulcanized rubber or others unknown rubber it is 3 seconds. For
Shore C model (Micropore Material Durometer), it is within 1 second
to read the value after durometer attach to the material
completely. If adopting other test time, it should be pointed out
in test report.
3. Estenstion rod
The test stand is equipped with extension pole, specially designed
for measuring the thick samples, 100mm in length. When the sample
thickness >16mm, use the extension rod to take measurements, the
specific steps are as follows: (1) Unscrew the handwheel of
crossbeam, unload the upper part of test stand. (2) Turn the lower
part up side down, hold the base and glass stage to avoid
collision. Unscrew and remove a screw connects the base and column
with hexagon wrench counterclockwise, and then remove the column,
put away the base, pay attention to avoid the collision of glass
stage. (3) Pick up the column and the extension rod, connect them
and screw tight. (4) Inserted the connected column and extension
rod into the concave hole of the base. Invert them and hold steady,
connect them with the screw disassembled in step 2, and then use
the hexagon wrench to screw clockwise, upside down. Pay attention
to avoid the collision of glass stage. (5) Set back the upper part
onto the column, tighten the handwheel fixing beam structure
4. Caution
(1) The test stand is only applied for our shore durometer. When
installing different mode of durometer, please adjust quality of
weight first according to requirements. GB/T531.1-2008 have rule
for the adjust of total quality as below: Shore A and Shore AO
model is 1 Kg; Shore C model is 10 Kg ;(In HG/T2489-2007) Shore D
model is 50 Kg; Shore AM model is 0.250 Kg; Note:Total quality
includes quality of lock screw,designation weight, screw,
installation pole, and durometer.
(2) Under environment without shock,the max pressing speed of test
could not be above 3.2mm/s.
(3) Test specimen requirements and regulation, according to sample
the corresponding standard.
(4) Glass stage is fragile, this support, when using and handling,
pay attention to the protection, avoid violent collision
5.Maintance
Please clean the test stand after using it to avoid rust. Except
for the damage caused by human factors,we promise that the
maintenance is one year and supply technical service for ever
