International Code Council Standards are a series of standards for buildings, unifying certain aspects of their design and construction to promote compatibility and reliability. They are revised and re-released every 3 years to stay up to date. These are the codes found in the International Plumbing Code.
The basic appeal of the Commentary is thus: it provides in a small package and at reasonable cost thorough coverage of many issues likely to be dealt with when using the International Plumbing Code-and then supplements that coverage with historical and technical background. Reference lists, information sources and bibliographies are also included.
