ANSI B11

ANSI B11 Standards are joint Standards, that were developed by associations

such as e.g. the Association for Manufacturing Technology (AMT) and the Robotic

Industries Association (RIA).

The hazards of a machine are evaluated using a risk analysis/assessment. Risk

analysis is an important requirement acc. to NFPA79, ANSI/RIA 15.06, ANSI

B11.TR–3 and SEMI S10 (semiconductors). Using the documented results of a risk

analysis, suitable safety systems can be selected based on the safety class ob-

tained as a result of the particular application.
