PPL also holds interests in partner-operated producing fields, including the Qadirpur, Sawan and Miano gas fields and the Tal, Nashpa and Gambat blocks, alongside its own operated fields. It also operates fields such as Kandhkot, Mazarani and Chachar. This page explains what to look for in an IECEx mobile phone for PPL, and where the IS-04Z1 stands against that list today.

Supplier approval · PPL
How suppliers reach PPL
PPL runs an e-procurement portal (eprocurement.ppl.com.pk) through which tenders are issued and bids submitted; confirm vendor registration steps with its support team. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.
Field notes · PPL
More about PPL that matters for portable equipment
PPL: projects and investment
In December 2019 the company announced new oil and gas discoveries in Sindh and Balochistan, so new well sites and gathering facilities are being added in both provinces.
PPL: rules and approvals
The company was listed on the Karachi Stock Exchange in 2004 after an initial public offering, so it follows listed-company governance and procurement disclosure rules.
PPL: background
Pakistan Petroleum Limited was incorporated on 5 June 1950, inheriting the assets of the Burmah Oil Company, which sold its remaining equity to the government in 1997, so it is a long-established producer.
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 PPL. Visiting service companies and EPCs often carry IECEx documentation from other markets, which is useful when they work on gas gathering at Sui or compression at Kandhkot. A reviewer should read the certificate of conformity with its schedule of conditions, not just the front page. For the IS-04Z1, IECEx work is in progress.

Questions · PPL
Frequently asked questions
Can PPL buy the IS-04Z1 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 mobile phone for PPL 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.
How does PPL approve suppliers?
PPL runs an e-procurement portal (eprocurement.ppl.com.pk) through which tenders are issued and bids submitted; confirm vendor registration steps with its support team.
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.
How do suppliers approach PPL?
PPL buys through its own procurement department, normally by tender and vendor registration, with technical review by the operating asset. Confirm the current process and certification requirements directly with PPL's procurement before offering equipment.
How does desert heat affect phones used at Sui or Kandhkot?
Both areas are hot and dry, with high summer temperatures and dust. Handheld devices should have a suitable operating temperature range, good dust protection and a battery that tolerates heat, and the site can confirm its own limits and any restrictions on devices in direct sun.
Would the phone be suitable for gas fields in Balochistan and Sindh?
The IS-04Z1 is designed for intrinsically safe handheld use with IP68 protection, but a final decision depends on the certificate, the gas group and the area classification at each field. Heat, dust and distance from charging points should be planned for. No certificate has been issued yet, so ask PPL's HSE team.
