For projects in Saudi Arabia, IECEx is the certification that actually matters. ATEX is a European Union legal directive with no jurisdiction in Saudi Arabia — SASO’s SALEEM SABER platform and Saudi Aramco’s engineering specifications reference IECEx, not ATEX. Equipment certified only to ATEX, without an accompanying IECEx Certificate of Conformity, has been rejected at Saudi site gates and held in customs. Both certifications are built on the same underlying IEC 60079 standards, but only one is recognized on Saudi paperwork.
What ATEX Actually Is
ATEX (“ATmosphères EXplosibles”) is a European Union legal framework, made up of two directives: one governing equipment design and manufacturing, the other governing employer obligations for worker protection in hazardous areas. It’s mandatory for equipment sold or used within the EU — but it carries no legal standing outside it. A supplier marketing “ATEX-certified” cable or components to a Saudi buyer isn’t wrong that the product is safe; the problem is that ATEX certification alone doesn’t satisfy what Saudi import and site-acceptance systems check for.
What IECEx Actually Is
IECEx is an international certification scheme run by the International Electrotechnical Commission, built on the same IEC 60079 series of standards that ATEX also references. Unlike ATEX, it’s not tied to any single country’s legal system — it’s a voluntary global scheme, but one specifically built for cross-border recognition. Critically, there’s no self-certification path under IECEx: equipment goes through an accredited IECEx Certification Body (ExCB), which issues a Certificate of Conformity (CoC) that gets published in the public IECEx Online Certification System (OCS) — meaning a Saudi buyer or site inspector can independently verify a certificate rather than taking a supplier’s word for it.
Why This Matters Specifically in Saudi Arabia
SASO — the Saudi Standards, Metrology and Quality Organization — runs the SALEEM SABER platform, the mandatory conformity assessment and customs clearance system for goods entering the Kingdom. For equipment used in explosive atmospheres, SASO recognizes IECEx certificates through its SASO IECEx Recognition program, not ATEX. Saudi Aramco’s own engineering specifications go further, explicitly accepting equipment certified under the IECEx Certified Equipment Scheme, with method-of-protection markings cross-referenced against NEC Article 505 — a detail that catches suppliers off guard if they’re used to European-only paperwork.
The practical consequence: equipment shipped with ATEX documentation only, and no IECEx Certificate of Conformity, can clear a European customs process without issue and still get rejected at a Saudi site gate or held in a bonded warehouse during import — a real, documented failure mode, not a theoretical one. Projects in Jubail, Yanbu, and other Eastern Province facilities have lost weeks to exactly this gap.
What Actually Needs Certification in a Heat Trace Circuit
Hazardous-area certification isn’t a single stamp on the cable — every component in a classified-zone circuit needs its own appropriate rating:
- Heat trace cable itself — rated for the zone’s gas or dust group and temperature class
- Junction boxes and connection kits — separately certified, since a non-rated junction box compromises an otherwise-certified cable run
- Thermostats and control panels — control equipment installed within the classified zone needs the same certification tier as the cable
- Cable glands — a commonly overlooked component; an uncertified gland at a certified junction box still creates a compliance gap
Zone Classification: The Starting Point Before Certification
Hazardous areas are classified by zone before any equipment gets specified — Zone 0/1/2 for gas and vapor atmospheres, Zone 20/21/22 for combustible dust, based on how likely and how often an explosive atmosphere is present. This classification, done by the site’s process safety team, determines which equipment protection level is actually required — specifying certified equipment for the wrong zone either overspends on unnecessary protection or underspends on a genuine safety gap. Confirm zone classification with your site’s safety documentation before requesting quotes, not after.
Documentation to Have Ready Before an EPC or Site Safety Review
- IECEx Certificate of Conformity (CoC) for each certified component, verifiable against the IECEx OCS database
- Method-of-protection marking matched to the equipment’s actual installation zone
- Equipment datasheets confirming gas/dust group and temperature class compatibility with site classification
- For Aramco-scoped projects specifically, documentation showing NEC Article 505 cross-reference alongside the IECEx marking, per Aramco’s engineering specification requirements
Equipment Certification vs. Personnel Certification — Two Separate Requirements
Everything above covers equipment. Saudi projects also require certified people to install, inspect, and maintain that equipment — a separate IECEx scheme (Certificate of Personal Competence, or CoPC) most equipment-focused guides skip entirely.
The CoPC scheme certifies individual competency units, commonly referred to by number:
- Ex001 — Explosive Atmospheres: Foundation Knowledge (baseline requirement for most roles)
- Ex002 — Explosive Atmospheres: Classification of Hazardous Areas
- Ex003–Ex004 — Installation, initial inspection, and testing of Ex equipment
- Ex006–Ex008 — Overhaul, repair, and specialist inspection roles
EPC contractors bidding on Jubail, Yanbu, or other Aramco-scoped work typically need Ex001 and Ex002 at minimum for field personnel, with inspection engineers and specialists needing additional units depending on scope. A technically compliant equipment package still fails a project if the installation and maintenance team can’t show matching personnel certification — this gets checked separately during contractor pre-qualification and CV review, not bundled with equipment paperwork.
Structural Difference: Two ATEX Directives vs. Four IECEx Schemes
Beyond geography, the two systems are organized differently. ATEX operates through exactly two directives — one for equipment, one for workplace safety obligations. IECEx runs four separate schemes covering equipment certification, service facility certification, and the personnel competency certification (CoPC) described above. This is part of why IECEx documentation for a Saudi project often involves more than one certificate — equipment and personnel are certified through genuinely separate processes, not a single combined paper trail.

How Paklink LLC Supports Your Certification Requirements
Paklink LLC stocks ATEX, IECEx, and TR CU certified explosion-proof equipment under our MAMX product line — including explosion-proof control panels, junction boxes, terminal boxes, and distribution panels built for classified hazardous areas. For heat trace circuits specifically, that means the control and connection hardware in your circuit can carry the same certification tier as the cable itself, rather than sourcing cable and enclosures from separate suppliers with mismatched documentation. Before any hazardous-area component ships for a Saudi project, we confirm the certificate matches the specific product variant you’re ordering, and provide that documentation alongside your shipment. If your project falls under Aramco’s engineering specifications, tell us upfront — we’ll flag any components that need the additional NEC Article 505 cross-reference documentation before you place the order, not after it’s already in transit.

FAQ
Is ATEX certification useless for a Saudi Arabia project?
Not useless — ATEX-certified equipment is often also IECEx-certified since both reference IEC 60079, and dual certification is increasingly common among manufacturers. The issue is relying on ATEX documentation alone; always confirm an IECEx Certificate of Conformity exists and is listed in the IECEx OCS before shipping.
Does SASO ever accept ATEX-only equipment?
SASO’s recognition program for explosion-protected electrical equipment is built around IECEx certificates specifically. Confirm current requirements for your exact product category with SASO or your customs broker, since scope has expanded over time to cover more product types.
What happens if hazardous-area equipment arrives without the right certification?
It can be held at customs, rejected at the site gate during delivery inspection, or flagged during a pre-installation safety review — all of which delay a project and can trigger storage fees while documentation gets sorted out.
Do I need IECEx certification on every component, or just the cable?
Every component installed within the classified zone — cable, junction boxes, glands, thermostats, control panels — needs appropriate certification. A single uncertified component in the circuit creates a compliance gap regardless of how well-certified the rest of the system is.
Who determines the zone classification for my site?
The facility’s process safety or HSE team classifies zones based on the specific process, materials, and layout — this isn’t something a cable supplier determines. Confirm classification internally before requesting equipment quotes.
Does IECEx certify people as well as equipment?
Yes — through a separate scheme, the Certificate of Personal Competence (CoPC), covering units like Ex001 (foundation knowledge) through Ex008 (specialist inspection). This is checked independently from equipment certification, typically during contractor pre-qualification.
