Introduction
This fire test has been developed for use by those responsible for selection of construction products
which, whilst not completely inert, produce only a very limited amount of heat and flame when
exposed to temperatures of approximately 750 °C.
The limitation of the field of application to testing homogeneous products and substantial components
of non-homogeneous products was introduced because of problems in defining specifications for the
specimens. The design of the specimen of non-homogeneous products strongly influences the test
results, which is the reason why non-homogenous products cannot be tested to this standard.
Safety warning
The attention of all persons concerned with managing and carrying out this test is drawn to the fact
that fire testing may be hazardous and that there is a possibility that toxic and/or harmful smoke and
gases may be evolved during the test. Operational hazards may also arise during the testing of
specimens and the disposal of test residues.
An assessment of all potential hazards and risks to health should be made and safety precautions
should be identified and provided. Written safety instructions should be issued. Appropriate training
should be given to relevant personnel. Laboratory personnel should ensure that they follow written
safety instructions at all times.
EN 1182:2002 (E)
1 Scope
This European Standard specifies a method of test for determining the non-combustibility
performance, under specified conditions, of homogeneous building products and substantial
components of non-homogeneous building products.
Information on the precision of the test method is given in annex A.
2 Normative references

publications. These normative references are cited at appropriate places in the text, and the
publications are listed hereafter. For dated references subsequent amendments to or revisions of, any
of these publications apply to this European Standard only when incorporated in it by amendment or
revision. For undated references the latest edition of the publication referred to applies (including
amendments).

3 Terms and definitions
For the purpose of this European Standard, the terms and definitions given in EN ISO 13943, together
with the following, apply:
3.1

4 Test apparatus
4.1 General
4.1.1 The test apparatus shall be capable of creating the conditions specified in 7.1. A typical
design of furnace is given in annex B; other designs of furnace may be used.
4.1.2 All dimensions given in the description of the test apparatus are nominal values, unless
tolerances are specified.
4.1.3 The apparatus shall consist of a furnace comprising essentially a refractory tube surrounded
by a heating coil and enclosed in an insulated surround. A cone-shaped airflow stabilizer shall be
attached to the base of the furnace and a draught shield to its top.
4.1.4 The furnace shall be mounted on a stand and shall be equipped with a specimen holder and a
device for inserting the specimen-holder into the furnace tube.
4.1.5 Thermocouples, as specified in 4.4, shall be provided for measuring the furnace temperature
and the furnace wall temperature. annex C gives details of additional thermocouples to be used if the
specimen surface temperature and the specimen centre temperature are required. The thermal
sensor, as specified in 4.5, shall be provided for measuring the furnace temperature along its central
axis.
4.2 Furnace, stand and draught shield
4.2.1 The furnace tube shall be made of an alumina refractory material as specified in Table 1, of
density (2 800 ± 300) kg/m and shall be (150 ± 1) mm high with an internal diameter of (75 ± 1) mm
and a wall thickness of (10 ± 1) mm.

4.2.2 The furnace tube shall be fitted in the centre of a surround made of insulating material
150 mm in height and of 10 mm wall thickness, and fitted with top and bottom plates recessed
internally to locate the ends of the furnace tube. The annular space between the tubes shall be filled
with a suitable insulating material. A typical example is given in annex B.
EN 1182:2002 (E)
4.2.3 To the underside of the furnace shall be attached an open-ended cone-shaped air flow
stabilizer 500 mm in length, and reducing uniformly from (75 ± 1) mm internal diameter at the top to
(10 ± 0,5) mm internal diameter at the bottom. The stabilizer shall be manufactured from 1 mm thick
sheet steel, with a smooth finish on the inside. The joint between the stabilizer and the furnace shall
be a close, airtight fit, with a smooth finish internally. The upper half of the stabilizer shall be insulated
externally with a suitable insulating material. A typical example is given in annex B.
4.2.4 A draught shield made of the same material as the stabilizer cone shall be provided at the top
of the furnace. It shall be 50 mm high and have an internal diameter of (75 ± 1) mm. The draught
shield and its joint with the top of the furnace shall have a smooth finish internally, and the exterior
shall be insulated with a suitable insulating material. A typical example is given in annex B.
4.2.5 The assembly of the furnace, stabilizer cone and draught shield shall be mounted on a firm
horizontal stand which shall be provided with a base and draught screen attached to the stand to
reduce draughts around the bottom of the stabilizer cone. The draught screen shall be 550 mm high
and the bottom of the stabilizer cone shall be 250 mm above the base plate.
4.3 Specimen holder and insertion device
4.3.1 The specimen holder shall be as specified in Figure 1, and shall be made of nickel/chromium
or heat-resisting steel wire. A fine metal gauze tray of heat-resisting steel shall be placed in the
bottom of the holder. The mass of the holder shall be (15 ± 2) g.
4.3.2 The specimen holder shall be capable of being suspended from the lower end of a tube of
stainless steel having an outside diameter of 6 mm and a bore of 4 mm.
4.3.3 The specimen holder shall be provided with a suitable insertion device for lowering it precisely
down the axis of the furnace tube without shock, so that the geometric centre of the specimen is
located rigidly at the geometric centre of the furnace during the test. The insertion device shall consist
of a metallic sliding rod moving freely within a vertical guide fitted to the side of the furnace.
