Specific techniques ensure that mistakes and errors are avoided across the entire life-cycle. Annex E gives worked examples of the application of the software safety integrity tables in BS EN for safety integrity levels 2 and 3.

Central to the standard are the concepts of probabilistic risk for each safety function. Errors introduced anywhere from the initial concept, risk analysis, specification, design, installation, maintenance and through to disposal could undermine even the most reliable protection.

IEC is a basic functional safety standard applicable to all kinds of industry.
