Performance comparison between old UK performance classes and the new Euroclasses.

Summary of structural fire protection performance

The harmonisation of technical standards within Europe, and the

integration of EN13964 (Suspended

ceilings Requirements and test

methods) into national legislation,

means that there is now one series of

harmonised European test methods

and classifications for the reaction to fire

of suspended ceilings.These new reaction to fire ֑Euroclasses replace the old national test methods

for showing the performance of ceilings

in order to meet national building

regulation requirements for internal

linings. As reaction to fire is one of the essential safety requirements

identified for suspended ceilings, the

Euroclass classification is one of the

mandatory elements on the CE mark

for suspended ceiling tiles and grids.The Euroclasses rate from A1 through to F, as shown in the table opposite,

with A1 being the best reaction to

fire performance and F the worst.

Each member state then sets the

performance level required for different

areas and building types within their

own building regulations.

Depending upon the reaction to fire test(s) conducted, the rating may

include an additional classifications for

smoke production and flaming droplets.

Smoke and flaming droplets are

regulated in some European countries.

Smoke production is rated from s1

(the least smoke produced) to s3

(no limit to amount of smoke produced).

Flaming droplets is rated from d0

(no flaming droplets) to d2 (no limit

to flaming droplets).Throughout Europe, there is a requirement for a buildingҒs structure to

be protected from fire. This is primarily

for the structure to remain stable

during a fire to allow the occupants to

escape and also to enable fire fighters

to work without threat of the buildings

collapse. The duration of the required

protection will usually depend upon

the height of, and location within, the

building (i.e. typical floor, basement,

roof construction etc), whether

there is any active methods of fire

protection (sprinklers etc) and the type

of construction to be protected (steel

beams, timber or mezzanine floors etc).A fire protecting suspended ceiling system is one of several important

methods of providing the fire protection

which fire degradable elements of the

structure require. Ceilings can be used

to enable a floor construction to meet

the duration of protection required by the building regulations that it could not necessarily provide on its own.There are many national test methods for establishing the structural fire

protection performance of a suspended

ceiling system, however, there are

also several European norms which

are acceptable in most European

countries, although there is not yet one

test method which is acceptable to all

member states.

The complete construction and assembly of the test installation is

important to the success of the test,

and Armstrong test many ceiling tiles

for their structural fire performance, but

always on Armstrong Trulok grid.There are many other details of the test construction that must be understood

and adhered to. These include:- main runner and hanger centres

- the type of top fixings and how the hangers are attached to them- the minimum depth of the ceiling void

- what % of the floor design load is tested- whether ceiling tile hold-down clips were used.Therefore a full version of the fire test assessment and/or report should

be obtained and carefully studied.

These details must be included in the

installation if the tested performance is

to be realised and they should be taken

into account when writing specifications

for ceilings intended to provide

structural fire protection.Untested products may be assessed by reference to the product attributes and

comparison to similar tested products,

provided this is supported by an

assessment report from a recognised

fire expert and should be provided with

the base test report that details how the

product should be installed to achieve

the assessed performance.

The location and type of various service

elements such as lighting fittings,

smoke detectors etc, are infinite

and the designer and installer must

satisfy themselves that they can be

integrated without reducing the tested

performance of the ceiling system. This

will usually require a test report from the

fitting manufacturer or an assessment

issued by the fire authorities. Without

these documents the designer or

installer may assume an everlasting

responsibility for the fire safety of the

building and occupants.As products may be modified or retested it is essential that their validity

is always checked prior to installation.

This will ensure that ceilings perform

to the standard required by legislation. All Armstrong test reports, certificates and assessments are freely available

on request. A full document is always

needed and must be read and any

limitations understood. Abridged

versions must be regarded as

undesirable as they will not show the

full test details and construction.
