South Africa: industry on the ground
South Africa is the world's largest producer of chrome, manganese, platinum and vanadium and the third-largest coal exporter, so mining is a major source of hazardous-area work.

More about South Africa that matters for portable equipment
South Africa: rules and approvals
The code references a family of SANS standards, including SANS 10086 on installation, inspection and maintenance of equipment in explosive atmospheres, SANS 1489 on connectors and SANS 1515 on gas measuring equipment for mines.
South Africa: rules and approvals
ICASA, based in Centurion, sets radio type approval, relying on EU test reports for spectrum, EMC and electrical safety, and a conformity label must be affixed to the equipment and the packaging.
South Africa: rules and approvals
South Africa has a National Code of Practice for Electrical Machinery in Hazardous Locations under the Occupational Health and Safety Act 1993, with a section on regulatory requirements for explosion-protected apparatus.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In South Africa. IECEx is the foundation for South Africa: the IS-04Z1 IECEx programme is in progress, and the South African Ex certificate is planned to follow it. For international contractors visiting Secunda or Sasolburg, a certificate of conformity with its schedule of conditions would be the reference document, read alongside the local approval once available.

Specifying an IECEx smartphone for South Africa
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · South Africa
Frequently asked questions
Can we buy an IECEx smartphone in South Africa today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an IECEx smartphone in South Africa cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which sites in South Africa does this cover?
The market guide for South Africa covers Secunda, Mpumalanga, Sasolburg, Free State, Milnerton, Cape Town, Mossel Bay, Western Cape, among others. Site-level pages are linked below.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Which South African authority approves radios and phones?
ICASA sets radio type approval, and it is described as relying on EU test reports covering spectrum use, EMC and electrical safety, with a conformity label on the equipment and packaging. SABS and NRCS handle some electrical-safety certificates separately. Confirm the route for your device with ICASA or an agent.
What conditions affect devices at South African mines and plants?
Conditions vary from hot, dusty surface sites to deep underground workings with heat and humidity. Check ingress protection, operating temperature range and battery life, and confirm site rules on device approval and gas detection with the mine or plant operator.
How would the handset cope with highveld temperature swings?
IP68 sealing and a rugged build are aimed at hot summers, cold winter mornings and dusty conditions. The approved ambient range will be stated on the certificate, which is in progress. Check that range against the coldest morning shift at your site before ordering.
