These standards have replaced the old national standards and users are encouraged to use them. However, it is clear that the old standards are still used, not least because many existing drawings and company specifications refer to them. Therefore, it is still possible to come across standards such as:

BS 1449 and BS1501 for flat products

BS 970  for long products

The US standards such as ASTM and ASME are very important and will never be replaced. Common standards are:
