13.3.1. Function Status Classification

The classes reported below comply with the Annex “ISO Failure Mode Severity Classification”, ISO

Standard 7637, and Section 1.

Note: The word “function” used here only concerns the function performed by the GL61x0.

Table 54. ISO Failure Mode Severity Classification

Class

Definition

CLASS A

All equipment/system functions are fulfilled normally (100% functional) during and after the

constraint.

The GL61x0 shall exhibit normal function during and after environmental exposure. The

GL61x0 performance shall meet the minimum requirements of 3GPP or appropriate wireless

standards.

CLASS B

All equipment/system functions are fulfilled normally during application of the constraint;

however, one or several of them may be out of the specified tolerances. After application of the

constraint, all functions automatically return within standard limits. The memories shall remain

in compliance with Class A.

The GL61x0 shall exhibit the possibility at all times to establish a voice, SMS or DATA call.

Unless otherwise stated, full performance should return to normal after the external influence

has been removed.
