PRODUCT TYPE
BS4568 and EN61386 are both British standards for galvanized steel conduit. BS4568 has been widely used in Commonwealth countries since 1970. This standard is the harmonized standard of the entire EU, but many parts of the Commonwealth still use the BS4568 standard like the Middle East and Asia.
In 2004, the International Electromechanical Commission (IEC) released IEC 61386. The new standard released is the fusion of EN50086 and BS4568. Generally, the Americas do not adopt the IEC standard, but Europe, Asia, and Africa all adopt the IEC standard. At present, the requirements for threading pipes in the Middle East, the European Union, Southeast Asia, and other regions all need to meet the requirements of EN 61386.
Galvanized steel conduit has a perfect performance in
Threading test
