scope:

This part of IEC TS 62876 establishes a standardized method to determine the

• stability

of films of graphene-based material by a

• temperature and humidity test.

It establishes a general methodology for reliability stress screening (RSS) to qualify the use of graphene-based material in its subsequent product value stage. The intention is to prepare test samples undergoing the same or similar failure mechanisms as the graphene-based material in the final product.

• Selected stress factors in this test to drive the failure mechanisms are low temperature, high temperature, change of temperature and damp heat with respect to test severity, test sequence, sample quantities and acceptance criteria.

• The RSS test procedure defined here supports reliability assessment in the design phase of a product by providing guidelines for selecting appropriate measurement methods and how to define specific pass/fail criteria.

• The described methodology does not replace traditional reliability tests on the final product level and will not provide full reliability data which allow the estimation of product lifetimes. If the samples pass the test, the design is called qualified in accordance with IEC 62876-3-1.
