4 Fire resistance classification

This classification applies to CMS as described in its product standard and does not apply to additional devices

to fix the CMS to the building structure for example screws, anchors etc.

CMS providing fire resistant support are classified with one or more of the following classifications listed in

Table 1:
Table 1 — Fire resistance classifications for CMS providing support
CMS-support classification Classification of cables
with intrinsic fire
resistance which can be
supported
P 15 P 15
P 30 P 30
P 60 P 60
P 90 P 90
P 120 P 120

The CMS-support classification obtained by this test is non-hierarchical. For example, a CMS-support

classified P60 is not for use with P15 and P30 cables unless it is also tested and classified with these specific

cables.
5 Documentation

The documentation of the manufacturer of the CMS should include all information necessary for the proper

and safe installation and use related to the classification according to Clause 4. The information should include:

• Reference to the classification of the CMS-support in accordance with Clause 4:

reference to the classification of the CMS-support in accordance with Clause 4,

• details of the cables that passed the test, and a statement that the classification is only applicable for

the specific cable(s) that passed the test;

NOTE 2 Rules for testing CMS-support for fibre optic cables according to EN 50582 and communication cables

according to EN 50289-4-16 are under consideration.
6.1.2 Furnace
The construction of the furnace is such that it:

• Is capable of accommodating the relevant test arrangement defined in 6.2.1 to 6.2.5;

---------------------- Page: 13 ----------------------
SIST-TP CLC/TR 50658:2022
CLC/TR 50658:2022 (E)

• Allows for the positioning of the sample to be at least 500 mm away from the centreline of the burners;

• Is capable of producing the temperature and pressure conditions according to EN 1363-1 for at least

120 minutes.

The furnace walls and ceilings constructed for the purpose of this test are left to dry in ambient conditions for

at least 16 hours prior to the test.

6.1.3 General arrangement for testing a CMS providing support for cables with intrinsic fire

resistance

For checking the continuity and integrity of the electrical circuit a three-phase transformer of sufficient capacity

to maintain the required test current, is connected to all of the conductors under test as shown in Figure 1

(Typical circuit arrangement).

Each CMS-support classification declared according to Table 1 is tested using a relevant set of P-classified

cables. Each set consists of six P-classified cables of the same classification. The cables are taken from three

different manufacturers with two cables of the same type from each manufacturer.
The set of P-classified cables consists of the following cable types:

• P-classified cables with an operating voltage of 230/400 V AC are represented by either 4 × 1,5 mm

or 5 × 1,5 mm conductors, and/or

• P-classified cables with a lower operating voltage are represented by either two pairs or four

conductors with the smallest conductor size in the family.

Indicating devices such as lamps or LEDs are used to determine the interruption of circuit continuity in the

conductors.
NOTE Figure 1 shows the connections for one cable.

The test is carried out with an operating voltage of 230/400 V AC and/or 110/190 V AC and/or the rated voltage

of the cable used for the test.

The test result is only valid for applications with an operating voltage equal to or lower than the operating

voltage used in the test.

The indicating devices are chosen to achieve a test current of approximately 0,25 A through each conductor.

Fuses used in the test procedure are 2 A Type DII complying with HD 60269-3. Alternatively, a circuit breaker

may be used. Where a circuit breaker is used, it has equivalent characteristics to the fuse in accordance with

Annex C of EN 50200:2015.

6.1.4 Test result

The sample passes the test if, taking into account the duration of the claimed classification, all of the following

conditions are fulfilled:

• At least 5 of the 6 cables are still functioning at the end of the duration of the claimed classification, and

• the 6 cable was functioning for at least 80 % of the duration of the claimed classification.

When the above conditions are fulfilled, the CMS-support can be classified according to Table 1 to support

cables with intrinsic fire resistance for any cable manufacturer.

If only both cables from one or two manufacturers are still functioning after the specified time period, the CMS-

support can be classified according to Table 1 to support cables with intrinsic fire resistance only for the

cable(s) that passed the test.

If an indicating device ceases to operate, it is determined first whether it is a failure of the conductor or a failure

of the indicating device.

In case of failure of the indicating device, replace the indicating device during the test.

6.2 CMS-support specific rules

6.2.1 Test for cable tray systems, mesh cable tray systems and cable ladder systems

6.2.1.1 General

Cable tray systems, mesh cable tray systems and cable ladder systems classified according to Table 1 are

tested in accordance with 6.2.1.2.
The test is carried out with the maximum:

• width of cable tray length and fitting, mesh cable tray length and fitting or cable ladder length and fitting,

• length of pendant,
• length of cantilever bracket,
• width of trapeze support,
as declared by the manufacturer.

The test arrangement is assembled and installed according to the manufacturer's instructions. Different jointing

methods or different jointing positions constitute different product types. Metallic cable tray systems, mesh

cable tray systems and cable ladder systems are connected to earth.

Wall mounted cantilever brackets used in the test are mounted to a rigid support construction simulating wall

mounting conditions. Cantilever brackets which are suitable for wall and pendant mounting need only be tested

in the pendant arrangement.

The cable is installed side by side in one layer uniformly distributed with the minimum bending radius as

declared by the cable manufacturer allowing a tolerance of +10 %. If a single cable tray, mesh cable tray or

cable ladder does not have enough space to accommodate all six cables, an additional identical cable tray,

mesh cable tray or cable ladder is used in the test arrangement.
6.2.1.2 Test requirements

The test arrangement comprises of a minimum length of the sample of 2,8 m with a minimum of two spans. All

spans are equ
