The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Norwich and the Norfolk coast. A marking check at Bacton would concentrate on natural gas, which usually sits in a lower gas group than hydrogen, so IIC marking offers margin. The operator's zone documents define the requirement for each terminal. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, pending certification.
The route · distribution
Distributing the IS-04Z1 in Norwich
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Norwich and the Norfolk coast. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Norwich and the Norfolk coast.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Norwich
Frequently asked questions
Can we buy an Ex-proof smartphone in Norwich 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 an Ex-proof smartphone in Norwich cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Norwich and the Norfolk coast would use it?
Likely candidates are gas terminal process areas, gas receipt and blending, interconnector terminals, offshore support port facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Norwich and the Norfolk coast?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Norwich and the Norfolk coast.
How does the coastal climate on the Norfolk coast affect phones?
The Norfolk coast is relatively dry by UK standards but exposed to wind and salt air, which can corrode connectors and fixings. For offshore wind and port work, look for good ingress protection and corrosion resistance, and ask the site about its own requirements.
Is Norwich itself a hazardous-area site or are the Ex sites elsewhere in Norfolk?
Norwich is mainly a service, research and distribution city, so most classified areas lie on the coast, around the energy port at Great Yarmouth, gas terminals and offshore wind and gas support bases, as well as in fuel depots and food or feed plants. Confirm the site classification with each operator.
Who approves equipment at Bacton?
Bacton is a complex of six gas terminals run by Shell, Eni, Perenco and National Grid, plus the Interconnector and BBL terminals. Equipment for terminal areas is normally approved by each terminal operator, so approvals may differ between neighbouring sites. Ask each operator for its own requirements.
