It takes into account, wherever possible, the mechanical robustness test methods a

27、s outlined in IEC 60068. NOTE Devices include cells and modules. The object of this standard is to establish uniform preferred test methods with preferred values for stress levels for judging the mechanical properties of liquid crystal display devices. In case of contradiction between this standard

28、and a relevant specification, it is the latter that should govern. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
