Discussion

Johannes Gleim Dec 3, 2014:
I am content, That the asker understood the difference between a cable laying method and a circuit.
Johannes Gleim Dec 1, 2014:
I would say "Low-voltage circuits are often run in insulated copper cables." or better "Low-voltage circuits are often wired by insulated copper cables."
"cabling" is non-countable, in fact, and cannot run anywhere. "cabling/wiring" are generic terms for the material "cable/wire" and the work "laying/routing".
Tony M Dec 1, 2014:
@ Johannes You wrote: "I tried to understand the reason for distinguishing between I/S circuit and I/S cabling, but failed."

Ah, but therein lies the whole crux of the issue!

On a certain level, 'circuit' and 'wiring' may refer to the same thing; but very often in EN, the term 'circuit' is used to refer to the abstract notion of a 'system': a low-voltage circuit, for example. In this meaning, it can be used as a countable.
On the other hand, 'wiring' almost invariably refers to the very concrete physical manifestation of the wires used to carry that circuit; as such, 'wiring' (or 'cabling') is almost invariably non-countable. Maybe the following simplistic sentence will help illustrate the important distinction I am trying to highlight here:

"Cabling for a low-voltage circuit is often run in insulated copper cable."
Johannes Gleim Dec 1, 2014:
@ Tony I tried to understand the reason for distinguishing between I/S circuit and I/S cabling, but failed. The I/S circuit consists of cables and the cables must be appropriate as well as the routing/laying of cables. All this is covered by the term "cabling". BTW, the connected devices must be I/S, too.

The term "câblage des informations" reminds me the old-fashioned telegram style, to cable or to wire messages. These messages can be confidentially or encrypted, but not be intrinsically safe.
//
How would you adjust the French wording order to reflect to correct sense?
Tony M Dec 1, 2014:
@ Johannes Thanks, but that's NOT what I'm trying to say! I don't at all believe it is the wiring that is I/S, but rather the circuits it is carrying, which are crucial to the I/S functions of other facilities.

I freely admit to being puzzled by the technical logic of that (how can 'information' of any kind contribute to a system's being I/S?) — but it certainly seems to correspond to the FR word order and to the information I found during my researches.
Johannes Gleim Dec 1, 2014:
With Tony as I said in my discussion entry (deleted). The data are not 'intrinsically safe', but the cabling for data transfer.
Tony M Dec 1, 2014:
@ Chris C. I think that's the whole problem!

From my research, it seems to me they ARE in fact talking about 'wiring for intrinsically safe data' — not that the data itself is 'intrinsically safe' per se, of course, but that it relates to I/S systems etc. I believe this is the intended meaning, and the reason for the otherwise puzzling source text wording, and the use of the term 'informations'; do also note the FR word order, which definitely (to me) seems to indicate that « de sécurité intrinsèque » qualifies « informations » and not « câblage » — at any rate, I was told off the other week by a FNS for using the word order like this, but wrongly!

wiring of the intrinsically safe signals/circuits/system

"Les circuits courant en sécurité intrinsèque sont séparés galvaniquement de tous les autres circuits non Ex de façon fiable jusqu'à une valeur de crête de 375␣ V de la tension nominale" (http://www.vegaswing.com/downloads/BA/21488-FR.pdf)

"The intrinsically safe circuits are reliably galvanically isolated from all not-intrinsically safe
circuits up to a peak value of 375␣ V of the nominal voltage." (http://www.vegaswing.com/downloads/BA/21488-EN.PDF)

"câblage des informations" is literally the "wiring of information", the "wiring of signals" (..?)

So...the wiring of intrinsically safe signals ..?

I see there are also results on Google for intrinsically safe circuits, systems, etc...

To be honest, I don't know this field well enough to help any further than this at this moment in time. :(

Thanks Tony - glad that you agree!
agree chris collister : "intrinsically safe data wiring" is shorter and should cover it. Obviously the reader will understand that the "wiring" is intrinsically safe, not the data!

Thanks Chris - "intrinsically safe data wiring" sounds much more English as well.
neutral Johannes Gleim : I would support 'intrinsically safe wiring/cabling' for data transfer, but this is quite different from 'intrinsically safe signals, circuits or systems' as proposed. Data cannot be 'safe'. Signals (messages) cannot be wired.

Some Explanations of terms:

Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over other protection methods. Areas with dangerous concentrations of flammable gases or dust are found in applications such as petrochemical refineries and mines. As a discipline, it is an application of inherent safety in instrumentation. High-power circuits such as electric motors or lighting cannot use intrinsic safety methods for protection.
http://en.wikipedia.org/wiki/Intrinsic_safety

Electrical equipment in hazardous areas
:
To ensure safety in a given situation, equipment is placed into protection level categories according to manufacture method and suitability for different situations. Category 1 is the highest safety level and Category 3 the lowest. Although there are many types of protection, a few are detailed
Flameproof d Equipment construction is such that it can withstand an internal explosion and provide relief of the external pressure via flamegap(s) such as the labyrinth created by threaded fittings or machined flanges. The escaping (hot) gases must sufficiently cool down along the escape path that by the time they reach the outside of the enclosure not to be a source of ignition of the outside, potentially ignitable surroundings.
Encapsulated m Equipment components of the equipment are usually encased in a resin type material
Pressurised/purged p Equipment is pressurised to a positive pressure relative to the surrounding atmosphere with air or an inert gas, thus the surrounding ignitable atmosphere can not come in contact with energized parts of the apparatus. The overpressure is monitored, maintained and controlled.
Intrinsically safe i Any arcs or sparks in this equipment has insufficient energy (heat) to ignite a vapour

Equipment can be installed in ANY housing provided to IP54.
A 'Zener Barrier' or 'opto isol' or 'galvanic' unit may be used to assist with certification.
A special standard for instrumentation is IEC/EN 60079-27, describing requirements for Fieldbus Intrinsically Safe Concept (FISCO) (zone 0, 1 or 2)
http://en.wikipedia.org/wiki/Electrical_equipment_in_hazardo...
Cabling vs Wiring
When it comes to installation of any electrical or electronic gadget or network then cabling and wiring form the nerves to carry electrical current or pulses. Cabling and wiring is almost one and the same thing with a slight difference that laying a cable defines that advance and sophisticated gadgets are connected through it when compared to wiring. Wiring is done for less sophisticated systems and general household gadgets are connected to electrical line through wiring.
http://www.differencebetween.com/difference-between-cabling-...

Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications using various kinds of cable, most commonly category 5e (CAT-5e), category 6 (CAT-6), and fiber optic cabling and modular connectors. These standards define how to lay the cabling in various topologies in order to meet the needs of the customer, typically using a central patch panel (which is normally 19 inch rack-mounted), from where each modular connection can be used as needed. Each outlet is then patched into a network switch (normally also rack-mounted) for network use or into an IP or PBX (private branch exchange) telephone system patch panel.

i. Physical barriers are also required to separate intrinsically safe wiring from other wiring.
4.2.2 Cabling and Wiring Practicess

Certification requirements for explosion-protected apparatus
:
All intrinsically safe circuits (Ex i circuits) shall have system certification from an approved test laboratory (ATL) to ensure that the various devices in the circuit, with the interconnecting wiring and cabling, are compatible and suitable for the application.
The following information shall be submitted for approval:
a. a loop diagram showing all equipment and cabling or wiring;
b. information about the equipment characteristics indicated on the loop diagram and in the form of a certificate by an approved test laboratory (ATL); and
c. information about cabling and wiring indicating cable types and lengths as well as resistance, capacitance and inductance characteristics.
