The use of Standards can be seen in all aspects of life - not just in engineering and design.
Standards reduce unnecessary duplication of effort, and provide a quality benchmark.
Engineers, designers, architects, etc., all use standards in their everyday work. In most countries, the use of standards is voluntary. However, technical regulations and legislation are often used to ensure the legal enforcement of specific standards. Many different bodies and organisations produce standards. It is not always easy to trace the exact standard that you require.
