South African SANS 164 – Southern Africa standard – an overview
The relevant standard is SANS, South African National Standard, and approval is by SABS, the South African Bureau of Standards. Other test houses may also test and approve to SANS 164. Approved products may be marked ‘SANS’, SANS164-X’ (where X: plug type) or ‘SABS’. Whilst not mandatory for South Africa, we supply plugs with partially-insulated live and neutral pins as an added safety feature, an industry standard created by Morvan Trading in the mid-1990s. Our quality department is ahead of regulatory requirements, meaning confidence and peace of mind from our customers.
Like its larger 16A brother, SANS 164-3 is a three pin 6A roundpin plug based on the old 5A BS546 standard, near-identical to the Indian plug. It is in the process of being phased out since the 1980s, and will need an adaptor to fit the normal 16A sockets. They are still occasionally used in lighting; an unearthed 2 pin version exists, but was removed from the standard in 2003.
SANS 164-4 is based upon SANS 164-1, but is ‘dedicated system’ used in specialist applications including UPS, clean earth, data and electronic settings. The normally round earth pin has a flat section to differentiate from the normal type.
The SANS 164-2 plug was introduced by SANS in 2014 to become the new preferred type in South Africa. It is a 3 pin 16A plug identical to the IEC 60906-1 and much smaller than the current SANS164-1.
The changeover in ZA is to be natural, rather than enforced, with both types used in conjunction; it is foreseen to take several decades before becoming fully established. The 2 pin unearthed versions are SANS 164-5 for 2.5A and SANS 164-6 for 16A. We currently only offer the SANS164-2 as a special production item: contact us for information and pricing.
