Note: about 'normal'
A - Testing period of specimen longer than two weeks is an
exception
B - Testing cannot be carried out for unexpected factors is an
exception
- Things to be noted
- Jinan Languang Lab is only responsible for testing data and
will not involved in solving legal disputes.
- Requirement of specimen:
Appearance of specimen-
No crease, no scratches, no pinholes and no contamination;
package specimen without crumple, without contamination, without
sloughing of permeable layer and no extrusion from outside
force.

specimen member = three / specimen of each kind/testing of each
kind
- Customers should provide information such as the full name,
specification, material ,batch number of specimen and
information about whether specimen should be returned
- Make clear the testing basis, testing standard and
orientation of gas transmission
- Testing report
If there is any objection about the testing data, customers should
give a formal notification within ten days from the date on which
testing report is provided. Deferred objection will not be accepted.
