Schutzkleidung gegen Hitze und Flammen - Teil 1: Prüfverfahren für vollständige Bekleidung - Messung der Wärmeübertragung unter Verwendung einer sensorbestückten Prüfpuppe (ISO/DIS 13506-1:2023)

Dieses Dokument legt die Gesamtanforderungen, Einrichtungen und Berechnungsverfahren fest, mit denen Ergebnisse erhalten werden, die zur Bewertung der Leistungsfähigkeit vollständiger Bekleidungen oder Schutzkleidungsensembles verwendet werden können, die einer Beflammung von kurzer Dauer ausgesetzt sind.
Dieses Prüfverfahren legt ein Bewertungssystem zur Charakterisierung des Hitzeschutzes fest, der von einlagigen und mehrlagigen, aus flammbeständigen Materialien bestehenden Kleidungsstücken bereitgestellt wird. Die Bewertung beruht auf der Messung der Wärmeübertragung auf eine lebensgroße Prüfpuppe, die bei einer Brandsimulation in einem Labor mit kontrolliertem Wärmestrom sowie kontrollierter Dauer und Flammenverteilung Konvektions  und Strahlungswärme ausgesetzt wird. Die Daten der Wärmeübertragung werden über einen vorgeschriebenen Zeitraum addiert, um das Ergebnis für die gesamte Wärmeübertragung zu erhalten. Bewertungsverfahren für die Wärmeübertragung und den Hitzeschutzfaktor des Schutzes der Prüfpuppe (TMPF) ermöglichen die Quantifizierung der Produktleistung.
Der Wärmestrom der Exposition ist auf eine Nennstärke von 84 kW/m2 und je nach Risikobewertung und Erwartungen an die Wärmeisolationsfähigkeit des Kleidungsstücks auf eine Dauer von 3 s bis 20 s begrenzt.
Die erhaltenen Messwerte gelten nur für die jeweiligen geprüften Kleidungsstücke oder Kleidungsensembles und nur für die festgelegten Bedingungen jeder Prüfung, insbesondere in Hinblick auf den Wärmestrom, die Expositionsdauer und die Flammenverteilung.
Dieses Prüfverfahren erfordert eine Bewertung durch Sichtprüfung, Beobachtung, Untersuchung und Dokumentierung des Gesamtverhaltens des Prüfstücks/der Prüfstücke vor, während und nach der Exposition. Die Auswirkungen von Körperhaltung und Bewegung sind nicht Gegenstand dieses Prüfverfahrens.
Die Wärmestrommessungen können auch zur Berechnung der voraussichtlichen Hautverbrennungen aufgrund der Exposition verwendet werden (siehe ISO 13506 2).
Dieses Prüfverfahren simuliert weder starke Strahlungsbeanspruchung, wie sie bei einer Kurzschlusslichtbogenexposition oder bei einigen Arten der Flammenexposition mit flüssigen oder festen Brennstoffen auftreten können, noch Expositionen durch nukleare Explosionen.
ANMERKUNG   Dieses Prüfverfahren ist komplex und erfordert sowohl beim Prüfaufbau als auch bei der Durchführung der Prüfung einen hohen Grad an technischem Sachverstand. Selbst geringfügige Abweichungen von den Anweisungen können bei diesem Prüfverfahren zu signifikant unterschiedlichen Prüfergebnissen führen.

Introduction
The purpose of heat and flame-resistant protective clothing is to shield the wearer from hazards
that can cause skin burn injury. The clothing is made from one or more materials. The evaluation of
materials for potential use in this type of clothing generally involves two steps. First, the materials
are tested to gauge their ability to limit flame spread. They are then tested to determine the rate of
transferred energy through them when exposed to a particular hazard. A variety of bench scale test
methods are used in these two steps. Bench scale test methods permit testing fabrics, seams, zippers,
pockets, badges, buttons or other closures, metal and plastic clips or other features that can be included
in a complete garment. Once suitable materials are identified, they are made into complete garments
or ensembles. The overall design and performance of the garment can be assessed on a manikin-fire
exposure system. This test method is not designed to measure material properties directly, but to
evaluate the interaction of material behaviour and garment design.
In this test method, a stationary, upright adult-sized manikin (male or female) is dressed in a complete
garment and exposed to a laboratory simulation of a fire with controlled heat flux, duration and flame
2
distribution. The average incident heat flux to the exterior of the garment is 84 kW/m , a value similar
to those used in ISO 9151, ISO 6942 and ISO 17492. The protection offered by the test specimens is
evaluated through quantitative measurements and observations. Heat flux sensors fitted to the surface
of the manikin are used to measure the heat flux variation with time and location on the manikin and
to determine the total energy absorbed over the data-gathering period. The data gathering period is
selected to ensure that the total energy transferred has been completed. These measurements are
suitable for use in predicting skin burn injury (see ISO 13506-2).
The fire simulations are dynamic. The heat flux resulting from the exposure is neither constant nor
uniform over the surface of the manikin/garment. Under these conditions, the results are expected to
have more variability than carefully controlled bench scale tests (Interlaboratory results are found in
Annex B).
Fit of the garment on the manikin is important. Variations in garment design and how the manikin
is dressed by the operator can influence the test results. A test garment or specimen size is selected
by the laboratory from the size range provided by the manufacturer to properly fit the laboratory’s
manikin. Variations in the fit of the test garment that can occur when sitting, bending or moving are not
evaluated.
Most manikins do not have sensors on the hands and feet, but it is possible to assess some aspects of
hand protection depending upon the specific design of the hands. All manikins contain heat flux sensors
in the head. The reason for this is that many outer garments include an integral hood, but not gloves or
footwear. Tests for gloves and footwear are covered by other ISO documents for specific end uses.
The ISO/TC 94, SC 13 and SC 14 committees and European Committee for Standardization (CEN
TC 162) specify the method described in this document as an optional part in the fire fighter standards
[11]
ISO 11999-3 and EN 469, and as an optional part in the industrial heat and flame protective clothing
standard ISO 11612. The National Fire Protection Association (NFPA) specifies a test method similar to
[13]
the one described in this document as part of a certification process for garments (see NFPA 2112 ).

DRAFT INTERNATIONAL STANDARD ISO/DIS 13506-1:2022(E)
Protective clothing against heat and flame —
Part 1:
Test method for complete garments — Measurement of
transferred energy using an instrumented manikin
1 Scope
This document specifies the overall requirements, equipment and calculation methods to provide
results that can be used for evaluating the performance of complete garments or protective clothing
ensembles exposed to short duration flame engulfment.
This test method establishes a rating system to characterize the thermal protection provided by
single-layer and multi-layer garments made of flame resistant materials. The rating is based on the
measurement of heat transfer to a full-size manikin exposed to convective and radiant energy in
a laboratory simulation of a fire with controlled heat flux, duration and flame distribution. The heat
transfer data are summed over a prescribed time to give the total transferred energy. A transferred
energy and thermal manikin protection factor (TMPF) assessment methods provide to quantify
product performance.
2
The exposure heat flux is limited to a nominal level of 84 kW/m and a durations of 3 s to 20 s dependant
on the risk assessment and expectations from the thermal insulating capability of the garment.
The results obtained apply only to the particular garments or ensembles, as tested, and for the specified
conditions of each test, particularly with respect to the heat flux, duration and flame distribution.
This test method requires visual evaluation, observation, inspection and documentation on the overall
behaviour of the test specimen(s) before, during and after the exposure. The effects of body position
and movement are not addressed in this test method.
The heat flux measurements can also be used to calculate the predicted skin burn injury resulting from
the exposure (see ISO 13506-2).
This test method does not simulate high radiant exposures such as those found in arc flash exposures,
some types of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions.
NOTE This test method is complex and requires a high degree of technical expertise in both the test setup
and operation. Even minor deviations from the instructions in this test method can lead to significantly different
test results.
