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 · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In South Africa. Highveld summers are hot, winter mornings are cold and storms are violent, with coal and mineral dust over everything. IP68 sealing keeps water and dust out, and the certificate will state the approved ambient range. IP68 is an ingress rating and gives no protection against explosion.

Specifying a rugged 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 a rugged smartphone in South Africa today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does a rugged 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.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
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.
