It may be possible that national regulations exceed the requirements laid down in this standard. In this case these requirements shall be precisely described. Special safety requirements, e.g. in the fields of electrical and mechanical engineering which are dealt with in other regulations shall be observed although they are not mentioned specifically in this standard. This standard is of relevance only to new wastewater treatment plants and new parts for existing plants designed and constructed after the effective date.
