SANS 211 212 213 214 215 222
SANS 61000-4-2 or IEC 61000-4-2
SANS 61000-4-3 or IEC 61000-4-3
CE certified must have a number and simply placing a symbol "CE" does not mean it is certified.
These processes cost thousands of Rands, and very few manufacturers do it. This is the reason they are cheap!
Beware of China Mall products, they do not follow these certification processes.
An electrician can not issue a COC unless the specific equipment installed has the necessary "SANAS" certification, which must be applied for at NRCS. If there is an existing IEC certificate, it makes the process of obtaining the local SANAS certificate a bit easier, but must still go through the process, which can take from 6 months to 2 years, and still costs a small fortune, especially if there are a number of derivatives of the same product, such as 12V, 24V, 36V, 48V. Each one must get a certificate.
This is a one reason why the local products seem so expensive. They require a minimum amount of filtering to pass the EMI and EMC and RF certification requirements, along with other safety requirements, which invariably adds extra cost to the product to get the certification.
