i wonder Is a flame retardant cable also fire rated?

thanks.

is a flame retardant cable not olsa fire rated. This is different.

1. Where is my nearest FP Cable Stockist?

To find your nearest stockist see our Stockist Finder page where you can find your nearest stockist by post code, town or county.
2. In what ways are FP Cables better than the competition?

a) FP Cables use Insudite – it's a tough composite insulation, resistant to impact, nicking and abrasion; all things that normally result in failure of silicone insulated cables.

b) Most FP Cables are dressable - the cable will retain the shape you give it during installation and stays where it's put for first fix.

c) FP Cables strip easily - there are no fiddly metallic or fibreglass tapes to remove in a separate operation so termination is cleaner and quicker.
3. Do FP Cables pass tests on one sample?

a) Yes – for example FP200 Gold  passes the fire alarm code of practice, BS 5839-1:2002 which requires standard fire resistant cable to pass EN 50200 Annex E. That's fire,impact and water spray for 30 minutes at 850°C on the same sample ie an integrated test.
4. What is the meaning of the CWZ test?

BS6387:1994 contains a set of separate fire, water and shock tests and the highest grade is CWZ. In order to meet CWZ and comply with the standard cable must pass the following three separate tests:

C – Resistance to fire at 950ºC for 3 hours
W - Resistance to fire and water at 650ºC for 30 minutes and
Z - Resistance to fire and mechanical shock at 950°C for 15 minutes
5. Can FP cables be joined?

If jointing is unavoidable then a fire resistant box containing ceramic connectors should be used.
6. What clips are required?

The FP FIREFIX fixing system is the fastest way to install most FP cables - using Spit Pulsa® gas nailing technology. The clip is made from non rusting stainless steel with a LS0H powder coating.

FP FIREFIX kit includes all parts necessary to install 500 clips with the Spit Pulsa fixing tool available separately. The tool uses gas nailing technology to fix the clip securely onto a wide range of materials including concrete, steel, composite steel decking, masonry and block work.

Copper "P" clips or steel ties can also be used to install some cable types but plastic or aluminium clips should not be used as sole means of support. Aluminium and plastic clips can easily melt or burn during a fire and the cable may collapse. Please see reference numbers in the datasheet.
7. What Glands are required?

Prysmian nylon glands are recommended for general installations. The gland is not part of the fire resistant cable support but is recommended to reduce the ingress of airborne dust particles. Brass or steel glands may be also used.
8. What is the maximum operating temperature?

For FP200 Gold minimum operating temperature is – 20°C and the maximum is + 70ºC as laid down in the cable construction standard BS 7629 as required by BS 5839 and BS 5266.
9. Why do some manufacturers offer fire resistant cable rated at up to 125ºC?

There is no obvious advantage offering a fire alarm cable that claims to be rated above 70°C:

a) Temperature limitation of connectors and accessories is usually 70ºC.

See BS 7671:1992 IEE Wiring Regulations 17th Edition clause 512 - 02 - 1.

b) Effect of cable temperature on adjacent components since the surface temperature of the cable is only likely to be 10ºC less than the conductor. If laid next to a PVC cable then the surface temperature of the cable must not exceed 70ºC. [Ref: BS7671: 1992 /IEE Wiring Regulations 17th Edition section 422 "Protection Against Fire And Harmful Effects".]

c) Touch temperature should be less than 90ºC. [ Ref BS7671: 1992 /IEE Wiring Regulations 17th Edition section 423 "Protection Against Burns".]

d) Fire alarm cables are normally sized on volt drop considerations rather than current ratings.
10. What cable lengths are available?

Standard lengths are always in stock for 50, 100 & 500m in the common sizes. Other lengths need to be made to special order please contact us for prices, lead time and minimum quantity.
11. What colours are available?

Standard colours are Red and White but other colours are available, including colour matches to special order, contact us for prices, lead time and minimum quantity.
12. What clip spacing is required?

Recommended clip spacings are given in our brochure and are generally 300mm horizontal and 400mm vertical installation.
13. What is the life expectancy of FP cables?

All fixed wiring cables including FP have a minimum design life in excess of 20 years and we expect them to last well in excess of that under normal operating conditions. Cables are subject to the standard guarantee as given in the Prysmian Terms and Conditions of sale.
14. Are ferrules required for FP Cable?

No – Prysmian replaced silicone rubber with Insudite in 1995 and Insudite is a tough, resilient composite material developed by Prysmian – ferrules are not needed.
15. Are FP Cables suitable for outside installations?

For external installation with exposure to UV, we recommend white or black sheathed FP. Do not use red sheathed FP outside without additional protection.

alla i added pic your topic.

Hi Alla,
Sorry you are going to have to be more specific before you can get the correct answer.
If, by Fire Rated, you mean that the cable has circuit integrity and will continue to function during a fire (commonly called Fire Resistance) then the answer is NO. A flame retardant cable is normally classified as one that will self extinguish when the source of the fire, the flame is removed, it will not continue to burn. most "fire rated" cables are also flame retardant but not many, if any, flame retardant cables are fire rated in the sense of they have circuit integrity in the event of a fire.
All fire tests are covered by National or International Standards, to avoid confusion you should quote the standard to which the cable must comply.
Hope this helps,
Peter

Flame Retardant Cables:
Standards:

IEC 60332: This standard tests the flame propagation of cables. It includes several parts:

IEC 60332-1: Tests flame propagation for single cables placed vertically.

IEC 60332-2: Tests flame propagation for single cables placed inclined.

IEC 60332-3: Tests flame propagation for bundled cables placed vertically.

Example:

A cable with a diameter of 10mm is tested under IEC 60332-1. A flame is applied to the bottom end for 60 seconds1. If the burning stops within 60 seconds and the charred portion is less than 50mm below the upper clamp, the cable passes the test.

Fire-Rated (Fire-Resistive) Cables:
Standards:

UL 2196: This standard tests the fire-resistance of cables. It measures how long a cable can maintain circuit integrity under fire conditions3. Cables are tested for durations like 30, 60, 90, and 120 minutes.

Example:

A fire-rated cable is tested under UL 2196 for 60 minutes. The cable must maintain its functionality and not exceed a certain temperature during this period4. If it passes, it is certified as a 60-minute fire-rated cable.

Sample Scenario:
Imagine you are designing a fire alarm system for a public building. You need cables that can prevent the spread of fire and maintain circuit integrity during a fire.

Flame Retardant Cables: You would use cables that meet IEC 60332 standards to prevent flame propagation and reduce smoke and toxic gas emissions.

Fire-Rated Cables: You would use cables that meet UL 2196 standards to ensure they can maintain circuit integrity for a specified duration (e.g., 60 minutes) under fire conditions.

By combining both types of cables, you can enhance the safety and reliability of the fire alarm system.
