mounted to provide a sealed enclosure. The opening of the test frame shall be sufficient to

accommodate the test specimen with its associated or supporting construction, in general an opening

of 3 m × 3 m is sufficient for most door types.

A fan system is used to create the pressure differential and, for testing to evaluate S , a heating

system is used to generate the temperatures specified in clause 5. The fan and the heating system

shall be able to replace air at ambient and medium temperature, as required, in order to compensate

for leakage rates through the test assembly.

Annex B provides an outline specification for a suitable apparatus but other designs are possible to

achieve the same objectives.
4.2 Instrumentation

SIST EN 1634-3:2005
EN 1634-3:2004 (E)
6.4 Verification

Where practicable, the size, thickness and material specification of the door assembly shall be

determined before the test to check the construction of the door against the manufacturer’s

specification and to allow adequate description of the tested assembly.

All gaps through which smoke can leak shall be measured and recorded. Generally these are gaps

between the edge of the door leaf/leaves and the door frame, between door leaves and at sill level.

When testing for ambient temperature only leakage to satisfy S classification, the gap between the

bottom of the door and the sill level may be tightly sealed with an impermeable material.

A full description shall be given of the conditions prevailing at each edge of the door leaf/leaves and

the presence and the nature of any seals.
7 Installation of test specimen

The test specimen shall be mounted as in practice, in an associated or supporting construction, in

accordance with the manufacturer's instructions, with appropriate gaps and clearances between the

fixed and moveable parts.

All gaps between the supporting or associated construction and test frame shall be tightly sealed with

an impermeable material.
8 Conditioning
8.1 Moisture content

The test construction shall be conditioned in accordance with EN 1363-1. Door assemblies made

entirely of non-hygroscopic materials, e.g. metal or glass, shall be left in the laboratory for at least

three days before testing. Any additional conditioning requirements in the relevant product standard

shall also be observed.
8.2 Mechanical conditioning

For details of the requirements on mechanical testing conditioning of the test specimen before smoke

leakage testing e.g. operational test or self closing test refer to the requirement and classification

standard prEN 14600.
Durability requirements are given in the relevant product standard.

SIST EN 1634-3:2005
EN 1634-3:2004 (E)
9 Application of instrumentation
9.1 Thermocouples

For the ambient temperature only test to evaluate S , two thermocouples shall be used to monitor the

temperature in the chamber. These shall be equally spaced across the chamber at mid-height of the

test specimen.

For the ambient and medium temperature test to evaluate S , nine thermocouples shall be used to

monitor and control the temperature inside the test chamber. The thermocouples shall be arranged in

three horizontal rows. These thermocouples shall be spread equally across the chamber with three

150 mm from the bottom edge of the opening in the test frame, three in the centre and three at ¾

height position. The hot junctions shall be positioned (100 ± 50) mm from the exposed face of the test

construction.
9.2 Pressure

The pressure measuring device head (see 4.2.2) shall be mounted in the test chamber at the centre

of the test specimen (100 ± 50) mm from the inside face of the test specimen.
9.3 Air flow
The equipment described in 4.2.3 shall be installed.
10 Test procedure
10.1 Pre-test procedures
10.1.1 General

After installation of the assembly in the associated or the supporting construction, but before it is

mounted in front of the test chamber, each door leaf, or moving element of a hinged door assembly,

shall be opened to an angle of 30° and closed 10 times, using the automatic closing devices, if

provided, to ensure the assembly operates normally. With other types of doors, such as folding,

sliding or rolling shutters, the opening and closing operation shall be carried out as far as practicable

to check the operation of the assembly. This procedure is not a durability test, for which special

procedures are available.
10.1.2 Retention force measurements

The retention forces for all door assemblies which incorporate closing devices and which are meant to

be opened without mechanical power shall be measured. These measurements are needed to

establish the magnitude of the forces used to retain the door leaves closed to ensure that they are

representative of those used in normal practice.

For each door leaf, the retention force shall be determined as given below. For double action doors

the retention force shall be determined for each direction of opening, and for folding doors the

retention force shall be determined in the direction of opening.

The retention forces for all door assemblies which incorporate closing devices operated by egressing

personnel without mechanical assistance shall be measured as follows:

Open the test door slowly, using a force gauge attached to the handle and operating against the

direction of closing, to a distance of the leading edge of the door leaf of 100 mm away from its closed

position. Record the highest gauge reading between the closed and 100 mm positions.

SIST EN 1634-3:2005
EN 1634-3:2004 (E)
10.1.3 Mounting

After checks and verifications, the test specimen in its associated or supporting construction shall be

mounted and sealed in front of the test chamber prior to performing the air leakage test.

For ambient temperature only testing to evaluate S , the threshold gap may be tightly sealed using an

impermeable material or may be sealed by an active drop seal or similar operational seal. Details

shall be recorded in accordance with 6.4 above.

The door shall be in its final closed position, unlocked and the key, if any, removed.

10.2 Air leakage test
10.2.1 Sequence of testing
Tests shall be carried out in the following sequence:

a) determine the leakage rate through the test chamber and any supporting or associated

(20) (20)
construction at ambient temperature i.e. Q + Q ;
app sup/assoc
(20)
b) determine the total leakage rate at ambient temperature i.e. Q ;
(200)
c) determine the total leakage rate at medium temperature i.e. Q ;

d) determine the leakage rate through the apparatus and any supporting or associated construction

(200) (200)
at medium temperature 200 °C, i.e. Q + Q .
app sup/assoc

When testing for ambient only leakage to satisfy S classification, only (a) and (b) are necessary.

NOTE The order of a) and b) is not important and may be reversed.
10.2.2 Procedure

10.2.2.1 Procedure for ambient temperature only testing to satisfy S classification

The leakage rate through the test specimen shall be measured at pressure differences of 10 Pa and

25 Pa, or for special purposes at the pressure difference specified by the sponsor. During

measurement of the leakage rate the pressure difference shall be maintained for 2 min and the value

of Q established at the end of this period using:
(20) (20) (20)
Q = Q – (Q + Q )
spec t app sup/assoc

The length of the gap between the fixed and moving components of the doorset (e.g. between the

door leaf and frame as well as, where appropriate, between the moveable elements) but excluding the

length of the threshold gap shall be measured and recorded.

10.2.2.2 Procedure for ambient together with medium temperature testing to satisfy S

classification

For medium temperature tests the average air temperature close to the face of the door shall be

raised from ambient temperature to the required stabilisation temperature of (200 ± 20) °C in (30 ± 5)

min in such a manner that the average air temperature is maintained within the limits shown in

Figure 1. The temperature distribution over the face of the door shall be controlled to (200 ± 40) °C as

measured by each thermocouple. During the heating up period, neutral pressure shall be maintained

in the test chamber.
