Joint Tensile Strengths
|
|
We conduct routine
tensile strength checks on a regular basis to satisfy our own quality
control requirements and in addition to this we can offer(by prior
arrangement) 'production batch testing' on your orders. The testing
is carried out on a purpose built tensometer.
|
|
|
A typical joint
sample is 140§® long and this is held in specally designed grips.
|
|
|
The joint sample
is elongated until breakage occurs and this depending on which material
can result in quite high elongation.
|
|
|
When the sample
breaks it is often at the join area. This does not infer weakness
but at such high elongation, a surface imperfection around the join
area will be the point of breakage.
|
|
The break as
you can see is at the join area but at 90 degrees to the cord stock.
|
|
This detail
shows how the vulcanised area has not failed and indicates good
quality vulcanisation.
