Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

This sixth edition cancels and replaces the fifth edition (ISO 1182:2010), which has been technically

revised. The main changes compared to the previous edition are as follows:

— a second furnace thermocouple has been introduced in Subclauses 4.4, 7.2.2, 7.2.4 and 8.3, Clause 9

and Figure 2;
— the calibration procedure of the furnace wall temperature has been adjusted;

Introduction

This fire test has been developed for use by those responsible for the 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 non-homogeneous products cannot be tested to this document.

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.
NOTE 1 An example of a typical furnace tube design is given in B.2.

An open-ended cone-shaped airflow stabilizer shall be attached to the underside of the furnace. The

stabilizer shall be 500 mm in length, and reduce uniformly from 75 ± 1 mm internal diameter at the top

to 10 ± 0,5 mm 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.
NOTE 2 An example of suitable insulating material is given in B.3.

4.2.2 Draught shield, made of the same material as the stabilizer cone, and 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.
NOTE An example of suitable insulating material is given in B.4.

4.2.3 Stand, firm and horizontal, on which the assembly of the furnace, stabilizer cone and draught

shield are mounted. There shall be 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 Specimen holder, as specified in Figure 1 and 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.

Due to ageing, specimen holders can lose weight. The mass of the holder shall be regularly checked.

4.3.2 Insertion device, suitable for lowering the specimen holder precisely down the axis of the

furnace tube smoothly and carefully, such 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.

The specimen holder for loose fill materials shall be cylindrical and of the same outer dimensions as the

specimen (see 5.1), and made of a fine metal wire gauze of heat-resisting steel similar to the wire gauze

used at the bottom of the normal holder specified in 4.3.1. The specimen holder shall have an open end

at the top. The mass of the holder shall not exceed 30 g.

4.4 Thermocouples, with a wire diameter of 0,3 mm and an outer diameter of 1,5 mm. The hot junction

shall be insulated and not earthed. The thermocouples shall be of either type K or type N. They shall be

of tolerance class 1 in accordance with IEC 60584-1. The sheathing material shall be either stainless steel

or a nickel-based alloy. All new thermocouples shall be artificially aged before use to reduce reflectivity.

NOTE A suitable method of ageing is to run a test without any test specimen inserted for 1 h.

The two furnace thermocouples, TC1 and TC2, shall be located with each of their hot junctions

(10 ± 0,5) mm from the tube wall and at a height corresponding to the geometric centre of the furnace

tube (see Figure 2). In the upper picture of Figure 2, the two furnace thermocouples (key 8 and 9) are

inserted in this plane to indicate the dimensions, i.e. the distances to the furnace wall and the specimen

surface, but are not located in this plane. The position of the furnace thermocouples in relation to each

other and to the surface thermocouple can be seen in the lower drawing of Figure 2. The correct position

of the thermocouple shall be maintained with the help of a guide attached to the draught shield.

The position of the thermocouples shall be set using the locating guide illustrated in Figure 3. The

length of the furnace thermocouple outside the guide shall be (40 ± 5) mm.

The furnace thermocouples shall be initially calibrated at 750 °C. Any correction term received at the

calibration shall be added to the output.
The furnace thermocouples shall be replaced after 200 test runs.

Details of any additional thermocouples required and their positioning are given in Annex C. The use of

these two thermocouples is optional.

4.5 Thermal sensor, made of a thermocouple of the type specified in 4.4, brazed to a copper cylinder

of diameter (10 ± 0,2) mm and height (15 ± 0,2) mm. The hot junction shall be at the geometrical centre

of the copper cylinder.

4.6 Contact thermocouple, made of a thermocouple of the type specified in 4.4. The thermocouple

shall be curved according to Figure 4.
