Directives or regulations
2014/35/EU Low voltage (LVD)

Although the standard’s status is withdrawn, it still has the presumption of conformity in the meaning of regulation 2014/35/EU and conformance with the regulation ’s requirements can be guaranteed by using the withdrawn version of the standard. The presumption of conformity is valid until a corresponding amendment is published in the Official Journal of the European Union.

This part of IEC 60664 applies to assemblies protected against pollution by the use of coating, potting or moulding, thus allowing a reduction of clearance and creepage distances as described in Part 1 or Part 5.                                                                               NOTE 1 When reference is made to Part 1 or Part 5, IEC 60664-1 or IEC 60664-5 are meant.                                                               This standard describes the requirements and test procedures for two methods of protection:
–  type 1 protection improves the microenvironment of the parts under the protection;
–  type 2 protection is considered to be similar to solid insulation.This standard also applies to all kinds of protected printed boards, including the surface of inner layers of multi-layer boards, substrates and similarly protected assemblies. In the case of multi-layer printed boards, the distances through an inner layer are covered by the requirements for solid insulation in Part 1.                                       NOTE 2 Wxamples of substrates are hybrid integrated circuits and thick-film technology.                                                                                                        This standard refers only to permanent protection. It does not cover assemblies that are subjected to mechanical adjustment or repair. The principles of this standard are applicable to functional, basic, supplementary and reinforced insulation.
