Written inspection procedures are essential to produce high-quality results. For example, trying to bake a cake without a recipe would be much more difficult than having a recipe to follow—so, therefore, written inspection procedures can be referred to as “recipes for success.”
While they are an investment, creating these “recipes for success” does not need to be difficult. Typically, it is useful to involve a small group of individuals who have relevant experience in the inspection process in order to represent different viewpoints, areas of expertise, and responsibilities. Once a written inspection procedure has been developed, it should be tested thoroughly and periodically reviewed by certified personnel to ensure that it continues to represent best practices.
Many inspection standards exist that can provide a foundation for simple written inspection procedures. For example, committees of professionals have worked with both the ISO and American Society of Testing Materials (ASTM) International to develop a number of relevant standards. ASTM International is a technical society and primary developer of voluntary standards, related technical information, and services that promote public health and safety. ASTM International also contributes to the reliability of products, materials and services.
These standards help to determine the performance of infrared systems. They also describe the best practice for inspections of building insulation, air leakage, electrical and mechanical systems, roofs, and highway bridge decks. Other organizations in individual countries, however, may have additional standards that can be used. For example, many have standards governing electrical safety that will apply directly to the work of thermographers inspecting electrical systems.
Due to the large variety of thermal imagers available today and the wide range of prices, infrared technology has become very easy to access. However, organizations that invest in the development of solid thermal imaging programs with inspection procedures and qualified personnel have a distinct advantage. Typically, they will have long-term benefits that other organizations may not receive!
