Technical and regulatory information

Legal information

Legal sources contain two broad types of information: legislation, which is the laws passed by a parliament; and case law, which describes the decisions made in the law courts and the reasoning and precedents used to make those judgements. 


Standards are documents that establish a common technical specification, so products and processes can work safely, reliably and consistently. Some standards provide a common terminology or set of symbols for a particular field, to make sure different organisations are talking about the same thing when they use a given term or symbol. Standards are very commonly used in all branches of building and construction.

Standards are published by a variety of different organisations, which often have a focus on a specific country or subject.

Standards do not have the force of law in themselves: however, laws and regulations will often require you to meet certain standards.
