An Introduction to API 653: 2009 and Its Related Codes

API codes, and the way in which they are written, are an acquired taste. As with all tastes that develop over time, some people eventually acquire it, some pretend to (because it sounds good) and others do not, but just put up with it. API codes are written from the viewpoint of the US refinery industry, so if you are not in the US refinery industry you may find some of the concepts and terminology different. In particular, the system of personnel responsibilities (what the inspector has responsibility for) bears little resemblance to the way that things work in many tank operator companies in the UK and Europe.
