12.2.1.2-3 Character Height

Characters used on labels should be sized to take into account viewing distances and illumination conditions.

Additional Information:
The character height recommendations in Guideline 11.3.1.5-1 should be observed. Character heights required for various viewing distances are given in Table 12.5. Under less- than-optimal viewing conditions, the preferred values should be used as minimums. The preferred values should also be used for critical markings associated with safety-related systems.
