Even if the amount of sample that you can supply is not enough, some tests allow assessment to a certain extent with a modified test method. Contact us in this case.
In principle, remaining sample is returned to the customer. Additional charge may be necessary for us to dispose it.
Contact us for other tests such as impact sensitivity test, incompatibility test, and test of immersion in flammable liquid (degradation test).
