Introduction

The purpose of this test is to measure the ability of a representative chimney construction to resist the

spread of fire from one fire compartment to another.
The fire can attack
— only from outside the chimney;
— as well as from outside the chimney entering into the chimney.

The test method is applicable to vertical and horizontal chimneys, taking into account joints and

openings as parts of the system chimney assembly.

The fire resistance from inside the chimney as a result of a sootfire (considered as resistance to fire

internal to external, according to EN 1443) has to be tested in accordance to the relevant product

standards and is not covered by this standard.

The test measures the length of time for which chimneys of specified dimensions, supported as they

would be in practice, satisfy defined criteria when exposed to fire only from outside or from both

inside and outside the chimney.

It is in the responsibility of the member states to require whether test specimen A or B (see 3.4) is to

be tested.

Caution: The attention of all persons concerned with managing and carrying out this fire resistance

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. Mechanical and operational hazards

may also arise during the construction of the test elements or structures, their testing and 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.

1 Scope

This document specifies a procedure to determine the fire resistance time for chimney constructions

(see normative references), shafts of chimneys or penetration elements as part of a chimney

construction under standardized fire conditions. The test examines the behaviour of chimney products

exposed to fire only from the outside or fire from the outside entering into the chimney. This standard

is used in conjunction with EN 1363-1. In chimneys combustion air supply ducts can also be included.

The standard also applies to such chimneys. Slanted chimneys are not included.

Annex A provides general guidance and background information. This document is not applicable to:

— sootfire resistance conditions;
— accessories unless they are included in the system chimney to be tested;
— one, two or three sided enclosures.

If the pressure inside the chimney can in practice decrease to lower values than - 40 Pa or increase to

higher values than + 5000 Pa it shall be considered that this cannot be covered by the test prescribed

in this standard.

6.3.2 Distances to the test furnace and between each other

There is no limit to the number of test specimen that may be tested simultaneously in the same test

furnace, provided that there is sufficient space to do so, in accordance with the dimensions shown in

the corresponding figures.

The maximum separation intended to use in practice shall be provided between the horizontal test

specimen and the floor, and if this is not possible, the distance between the horizontal test specimen

and the floor shall be at least 500 mm. The distance between the horizontal test chimney and the

furnace ceiling shall be at least 500 mm.

There shall be a minimum separation of at least 500 mm between the sides of the horizontal or

vertical test chimneys and the test furnace walls. The clearance between single specimens in the test

shall be at least 200 mm.
6.3.3 Openings in test specimen
6.3.3.1 Test specimen A

Test specimen A does not have any opening inside the test furnace. Cleaning and inspection doors and

draught regulators, if part of the system, have to be part of the test specimen inside and outside the

test furnace. During the test they are closed.
6.3.3.2 Test specimen B

One opening into each flue shall be provided for a test specimen B. For horizontal test specimens the

centre of the opening(s) shall be positioned (500 ± 25) mm from the end of the specimen opposite to

the penetrated test furnace wall. For vertical test specimens the centre of the opening(s) shall be

positioned at a distance of (1200 ± 200) mm above the floor.

In both vertical and horizontal chimneys the openings shall have the same width to height ratio as the

connected flue of the test specimen and the same opening area as the connected flue. Cleaning and

inspection doors and draught regulators, if part of the system, may not be taken into consideration

inside the test furnace.

If cleaning and inspection doors for an inspection opening or draught regulators on different levels are

part of the system chimney they have to be tested mounted according to the manufacturers instruction

outside of the furnace. If the system has already shown the resistance against soot fire the cleaning

and inspection doors for an inspection opening or draught regulators outside the furnace can be

omitted.
