Fire hazard testing - Part 6-1: Smoke obscuration - General guidance

This part of IEC 60695 gives guidance on:
a) optical measurement of smoke obscuration;
b) general aspects of optical smoke test methods;
c) consideration of test methods;
d) expression of smoke test data;
e) relevance of optical smoke data to hazard assessment.
One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications.

Ta del IEC 60695 podaja navodila o:
a) optičnih meritvah otemnitve dima;
b) splošnih vidikih optičnih dimnih preskusnih metod;
c) obravnavi preskusnih metod;
d) izražanju podatkov dimnih preskusov;
e) pomembnosti optičnih dimnih podatkov za oceno ogroženosti.
Ena od odgovornosti tehničnega odbora je, če je primerno, da uporabi temeljne varnostne publikacije pri pripravi svojih publikacij.

3.1 Terms and definitions
Replace the text of this subclause with the following:

For the purposes of this document, the terms and definitions given in ISO/IEC 13943, some of

which are reproduced below for the uses’ convenience, as well as the following apply.

3.1.1
combustion
exothermic reaction of a substance with an oxidizing agent

NOTE Combustion generally emits fire effluent accompanied by flames and/or glowing.

[ISO/IEC 13943, definition 4.46]
3.1.2
extinction area of smoke

product of the volume occupied by smoke and the extinction coefficient of the smoke

NOTE It is a measure of the amount of smoke, and the typical units are square metres (m ).

[ISO /IEC 13943, definition 4.92]
3.1.3
extinction coefficient

natural logarithm of the ratio of incident light intensity to transmitted light intensity, per unit

light path length
NOTE Typical units are reciprocal metres (m ).

[ISO/IEC 13943, definition 4.93]
3.1.4
fire

〈general〉 process of combustion characterized by the emission of heat and fire effluent and

usually accompanied by smoke, flame or glowing or a combination thereof

NOTE In the English language the term "fire" is used to designate three concepts, two of which, fire (3.1.5) and

fire (3.1.6), relate to specific types of self-supporting combustion with different meanings and two of them are

designated using two different terms in both French and German.
[ISO/IEC 13943, definition 4.96]
3.1.5
fire

〈controlled〉 self-supporting combustion that has been deliberately arranged to provide useful

effects and is limited in its extent in time and space
[ISO/IEC 13943, definition 4.97]
3.1.6
fire

〈uncontrolled〉 self-supporting combustion that has not been deliberately arranged to provide

useful effects and is not limited in its extent in time and space
[ISO/IEC 13943, definition 4.98]
3.1.7
fire effluent

totality of gases and aerosols, including suspended particles, created by combustion or

pyrolysis in a fire
[ISO/IEC 13943, definition 4.105]
3.1.8
fire hazard

physical object or condition with a potential for an undesirable consequence from fire

[ISO/IEC 13943, definition 4.112]
3.1.9
fire model
fire simulation

calculation method that describes a system or process related to fire development, including

fire dynamics and the effects of fire
[ISO/IEC 13943, definition 4.116]
3.1.10
fire scenario

qualitative description of the course of a fire with respect to time, identifying key events that

characterise the studied fire and differentiate it from other possible fires

NOTE It typically defines the ignition and fire growth processes, the fully developed fire stage, the fire decay

stage, and the environment and systems that impact on the course of the fire.
[ISO/IEC 13943, definition 4.129]

3.1.11
flashover

〈stage of fire〉 transition to a state of total surface involvement in a fire of combustible

materials within an enclosure
[ISO/IEC 13943, definition 4.156]
3.1.12
heat flux

amount of thermal energy emitted, transmitted or received per unit area and per unit time

NOTE The typical units are watts per square metre (W·m ).
[ISO/IEC 13943, definition 4.173]
3.1.13
ignition
sustained ignition (deprecated)
〈general〉 initiation of combustion
[ISO/IEC 13943, definition 4.187]

ignition
sustained ignition (deprecated)
〈flaming combustion〉 initiation of sustained flame
[ISO/IEC 13943, definition 4.188]
3.1.15
large-scale fire test

fire test, that cannot be carried out in a typical laboratory chamber, performed on a test

specimen of large dimensions

NOTE A fire test performed on a test specimen of which the maximum dimension is greater than 3 m is usually

called a large-scale fire test.
[ISO/IEC 13943, definition 4.205]
3.1.16
mass optical density of smoke

optical density of smoke multiplied by a factor, V/(Δm L), where V is the volume of the test

chamber, Δm is the mass lost from the test specimen, and
