What is PD IEC/TS 60079-40 - EA flammable liquid standards about?
Flammable and combustible liquids are liquids that can burn. They are classified, or grouped, as either flammable or combustible by their flashpoints. Generally speaking, flammable liquids will ignite (catch on fire) and burn easily at normal working temperatures and even more easily in explosive atmospheres (EA).
PD IEC/TS 60079-40 provides specific requirements for process sealing between a flammable process fluid and an electrical system where a failure could allow the migration of the process fluid directly into the premises wiring system.
Who is PD IEC/TS 60079-40 - EA flammable liquid standards for?
PD IEC/TS 60079-40 on EA flammable liquid standards is useful for:
- Operators of oil refineries
- Workers in an explosive atmosphere
Why should you use PD IEC/TS 60079-40 - EA flammable liquid standards?
PD IEC/TS 60079-40 contains requirements for evaluation, construction, and testing of single process seal equipment, dual process seal equipment, and add-on secondary process seals. The requirements of PD IEC/TS 60079-40 do not apply to conduit sealing devices, cable glands, and other wiring sealing methods addressed in the IEC 60079 series or other standards. Requirements for basic electrical safety and explosion protection are not addressed by this document but may apply to the equipment under investigation. The effects of leakage to the environment are not addressed by PD IEC/TS 60079-40.
The sections on general requirements including dual process seal equipment, equipment with limited pressure at the electrical connections and purged or pressurized equipment, and also type verification and tests have been discussed in thorough details in PD IEC/TS 60079-40. Using PD IEC/TS 60079-40 guidelines you can determine requirements for process sealing between a flammable process fluid and an electrical system where a failure could allow the migration of the process fluid directly into the premises wiring system. PD IEC/TS 60079-40 enables you to avoid any sort of hazards including explosion, fire, and electrical hazards in explosive atmospheres (EA).
