Qualifiers allow the SafetyProvider to indicate the correctness of values on a fine-grained level. It is good practice to attach qualifiers to each individual value sent within an SPDU. The qualifiers are part of the SafetyData and hence not within the scope of this document.

[RQ6.16] However, whenever qualifiers are used, the values shown in Table 27 shall be used, i.e. 0x1 for a valid value (“good”), and 0x0 for an invalid value (“bad”).

Table 27 – Example “application variables with qualifier”

Value	Qualifier
valid	0x1 (= good)
invalid	0x0 (= bad)

Checking of the qualifiers is done in the safety application.
