1. Foreword
This field of application report has been commissioned by Jiangsu Sainty Bancom
Wood Co. Ltd, T/A Sentry International, and relates to the fire resistance of 30 minute
Sentry Prolite fire resisting doorsets.
The report is for National Application and has been written in accordance with the
general principles outlined in BS EN 15725: 2010; Extended application reports on the
fire performance of construction products and building elements.
This field of application (scope) uses established empirical methods of extrapolation
and experience of fire testing similar door assemblies, in order to extend the scope of
application by determining the limits for the designs based on the tested constructions
and performances obtained. The scope is an evaluation of the potential fire resistance
performance, if the variations specified herein were to be tested in accordance with BS
476: part 22 and therefore can neither be considered for a CE marking application nor
can the conclusion be used to establish a formal classification against EN13501-2.
This field of application has been written using appropriate test evidence generated at
UKAS accredited laboratories
1
, to the relevant test standard. The supporting test
evidence has been deemed appropriate to support the manufacturers stated door
design and is summarised in section 3.
The scope presented in this report relates to the behaviour of the proposed door design
variations under the particular conditions of the test; they are not intended to be the
sole criterion for considering the potential fire hazard of the door assembly in use.
This field of application has been prepared and checked by product assessors with the
necessary competence, who subscribe to the principles outlined in the Passive Fire
Protection Forum (PFPF) guidelines to undertaking assessments. The aim of the PFPF
guidelines is to give confidence to end-users that assessments that exist in the UK are
of a satisfactory standard to be used for building control and other purposes.
The PFPF guidelines are produced by the UK Fire Test Study Group (FTSG) an
association of the major fire testing laboratories in the UK and are published by the
PFPF, the representative body for the passive fire protection industry in the UK.
1
Test evidence from overseas laboratories has also been considered as supporting evidence
for the designs in this assessment report. The test evidence is from a laboratory that has
been accredited by a national accreditation body which is a signatory of the International
Laboratories Accreditation Co-operation (ILAC).
2. Proposal
It is proposed to consider the fire resistance performance of the doorset design
described in the technical specification in section 4 of this report, for 30 minutes fire
resistance integrity, if the doorset were to be tested to the requirements of BS 476:
Part 22: 1987, Fire tests on building materials and structures – Part 22: Method for
determination of the fire resistance of non-load bearing elements of construction.
The field of application defined in this report is based on the fire resistance test
evidence for the doorset design, which is summarised in section 3. Analysis of specific
construction details that require assessment are given within this report against the
relevant element of construction, as appropriate.

3. Test Evidence
The test evidence summarised below has been generated to support the fire resistance
performance of the door designs that are the subject of this field of application.
3.1 Comparison of Test Standards
The ISO834 time/temperature curve used in BS 476: Part 22: 1987 test is the same as
within BS EN 1634-1, except for the use of Plate Thermometer device(s) for furnace
control in the EN test, which test data has shown to make the EN test more onerous.
This is due to the higher thermal inertia required for the plate thermocouple to read the
same temperature as the probe thermocouple used for the BS 476: Part 22 test,
particularly during the early stages of the test. It is therefore our assessment that the
same integrity performance would be achieved in a test conducted utilizing the
principles of BS 476: Part 22: 1987 and that test data generated to the requirements
of the EN test may therefore be used in support of this scope of application document,
written to the requirements of BS 476: Part 22: 1987.
Note: dimensions are in mm unless otherwise stated.
Abbreviations: (h) = height; (w) = width; (t) = thickness; (d) = depth.
Doorsets with latches fitted but disengaged for the test, are reported as ‘unlatched’.

5. Leaf Sizes
The approval for increased leaf dimensions is based on the tests listed in section 3
and takes into account the margin of over performance above 30 minutes integrity for
the design and the characteristics exhibited during test. Data sheets specifying the
maximum approved leaf sizes and graphs showing the permitted gradient between
maximum height and width, are contained in appendix D.
Unequal leaf double doorsets are covered by this assessment with no restriction on
the smaller leaf dimension. Doorsets containing leaves with smaller dimensions than
those stated are deemed to be less onerous and are therefore automatically covered.
6. Configurations and Orientation
6.1 Configurations
Based on the test evidence summarised in section 3, this assessment covers the
following doorset configurations:
Abbreviation
Description
Construction
Type
LSASD & ULSASD
Latched & unlatched single acting single
doorset
Types A and B
DASD
Double acting single doorset
Types A and B
LSADD & ULSADD
Latched & unlatched single acting double
doorset
Type B only
DADD
Double acting double doorset
Type B only
6.2 Orientation
The primary fire resistance test for this design was conducted with one doorset hung
such that the door leaf opened towards the fire, and one doorset hung such that the
door leaf opened away from the fire. Based on this testing, assessment is made that
doorsets to this design may be hung to open either away from or towards the fire risk
side of the doorset.
The fire risk may therefore be from both directions with respect to these doorsets.
7. Leaf Size Adjustment
Door leaves constructed to this design may be altered as follows:
Element
Reduction
Leaf Height
The manufactured leaf height may be reduced without restriction
from the bottom edge only.* The top rail must remain intact
Leaf
Width
Type A
The manufactured leaf width may be reduced without restriction
from either edge.*
Type B
The manufactured leaf width may be reduced from the closing,
lock edge, only. The hanging edge stile must remain intact.*
Timber lippings
The lipping dimensions stated in section 11 may be reduced by
20% for site - fitting purposes.
* Following reductions, all lippings must be reinstated in accordance with section 11.

Notes:
1. The single leaf doorset B tested in RF04016, evaluated the performance of the Sentry
Prolite design utilising a hardwood door frame (see graph contained in appendix D for
extended single leaf size range).
2. The doorset tested in RF01059B (AR2), evaluated the performance of the Sentry
Superlite design, utilising an MDF door frame (see graph contained in appendix D for
the permitted single leaf size range).
3. Timber used for constructing door frames must meet or exceed class J30 as specified
in BS EN 942: 2007, providing any defects are adequately repaired.
4. A 12mm deep planted stop is adequate for single acting frames whilst double acting
frames must may be scalloped or square. If frames are square, the maximum radius
to the corners of the leaf is 8mm. Frame joints must be mortice and tenoned, mitred,
butt, half lapped nailed or screwed and with no gaps.
