APPENDIX 1

THERMAL RADIATION TEST SUPPLEMENT TO FIRE RESISTANCE TESTS FOR WINDOWS IN "A", "B" AND "F" CLASS DIVISIONS

1 Scope

1.1 This appendix specifies a procedure for measuring heat flux through windows as a basis for characterizing their ability to limit the heat radiation in order to prevent the spread of fire and to enable escape routes to pass near the windows.

1.2 This procedure is an optional requirement and may be requested by some Administrations for windows in specific areas of a ship.

2 Test procedure

2.1 The window should be tested in accordance with resolution A.754(18) using the additional instrumentation as described below.

2.2 The term "window" includes windows, side scuttles and any other glazed opening provided for light transmission or vision purposes in a fire resistant division. The term "fire resistant division" includes bulkheads and doors.

3 Additional instrumentation

3.1 Additional instrumentation consists of a restricted-view total-heat fluxmeter calibrated with the restricted view to indicate incident heat flux. The fluxmeter should be water-cooled and capable of measuring heat flux 0 to 60 kW/m2. The fluxmeter should be calibrated at least once a year against a standard device.

3.2 The fluxmeter should be placed perpendicular to the centre of the window being tested, and in a position such that the centre of the fluxmeter's view coincides with the centre of the window^* (see the figure). The fluxmeter should be located at a distance greater than 0.5 m from the window, such that the view of the fluxmeter just includes part of the frame. However, the fluxmeter should not be located more than 2.5 m from the window. The dimension of the boundary and window frame seen by the fluxmeter, which remains outside the window should not exceed 10% of the total width seen by the fluxmeter on the surface of the sample. It should be calculated on the basis of restricted view angle of the fluxmeter and its distance to the sample surface.

* A satisfactory method of placing, mounting, and aiming the fluxmeter is as follows: A metal stand constructed of a pipe mounted on a sturdy base serves as an instrument tree to locate the fluxmeter at the required distance from the test specimen. A suitable holder for the fluxmeter is constructed by mounting a gun-sight mount on a lockable ball and socket joint. This joint provides flexibility for aiming the meter. The fluxmeter holder is mounted on the instrument tree at the appropriate height. A laser pointer is placed in the gun-sight mount and the mount is oriented such that the dot is in the centre of the window. The laser pointer is slipped out of the holder and replaced by the fluxmeter.

Figure

3.3 For windows whose greater dimension is less than 1.57 times the smaller dimension, only one fluxmeter is needed.

3.4 For oblong windows whose greater dimension is more than 1.57 times the smaller dimension, additional fluxmeters should be provided. The distance of the fluxmeters from the window should be adjusted such that the fluxmeters' view covers at least 50% of the window. However, the fluxmeters should not be located less than 0.5 m nor more than 2.5 m from the window.

Figure

4 Classification criteria

4.1 The peak heat flux (Ew) should be measured for the first 15 min of the test, for the first 30 min of the test, and for the entire duration of the test (i.e. 60 min for class "A" and 30 min for class "B" boundaries).

4.2 The peak heat fluxes (Ew) measured in accordance with paragraph 4.1 should be compared against the reference value (Ec) from the table.

4.3 If (Ew) is less than (Ec), the window is acceptable for installation in a boundary of the corresponding fire resistant classification.

Table 1 - Criteria for heat flux

Fire resistant division classification	Time period from beginning of test to	Heat flux Ec (kW/m²)
A-0	60 minutes	56.5
A-15	15 minutes 60 minutes	2.34 8.0
A-30	30 minutes 60 minutes	2.34 6.4
A-60	60 minutes	2.34
B-0	30 minutes	36.9
B-15	15 minutes 30 minutes	2.34 4.3

APPENDIX 2

CONTINUOUS "B" CLASS DIVISIONS

1 Scope

1.1 This appendix specifies the procedure for testing linings and ceilings for verifying that they are "continuous 'B' class linings" and "continuous 'B' class ceilings" and for evaluating full constructions to be "continuous 'B' class constructions".

1.2 This procedure is an optional requirement and may be requested by some Administrations for continuous "B" class divisions.

2 Test procedure and evaluation

2.1 The linings, ceilings and constructions should be evaluated in accordance with resolution A.754(18) using the arrangements described below.

2.2 The ceilings should be tested in accordance with paragraph 2.8 of the Annex to resolution A.754(18) except that the ceiling should be mounted on the horizontal furnace so that at least 150 mm high "B" class bulkheads are mounted on the furnace and the ceiling is fixed to these partial bulkheads by using the joining method as is intended to be used in practice. Such ceilings and the joining methods should be evaluated as required for ceilings in accordance with resolution A.754(18) and accordingly they should be classified as "continuous 'B' (B-0 or B-15, as applicable) class ceilings".

2.3 A lining which has been evaluated in accordance with resolution A.754(18) to be a "B" (B-0 or B-15, as applicable on basis of the lining test) class lining may be considered forming "continuous 'B' (B-0 or B-15, as applicable) class lining" in conjunction with a "continuous 'B' (B-0 or B-15, as applicable) class ceiling" and with the joining method used in the test (see paragraph 2.2 above) without further testing the lining.

2.4 An enclosed construction installed on an "A" class deck and formed by "continuous 'B' (B-0 or B-15, as applicable) class linings" and "continuous 'B' (B-0 or B-15, as applicable) class ceiling" should be considered forming "continuous 'B' class construction".

PART 5 - TEST FOR SURFACE FLAMMABILITY

1 Application

Where a product is required to have a surface with low flame-spread characteristics, the product shall comply with this part.

2 Fire test procedure

2.1 The surface materials shall be tested and evaluated in accordance with the test procedure specified in resolution A.653(16). For the purpose of this part, the total heat release value (Qt) for floor coverings given in section 10 of the Annex to resolution A.653(16) is replaced by 2.0 MJ. The test may be terminated after 40 min.

2.2 During fire tests for bulkhead, ceiling and deck finish materials and primary deck coverings (see part 6 of this annex for primary deck coverings), there are those specimens which exhibit various phenomena which cause difficulties in classification of the materials. Appendix to this part provides guidance on the uniform interpretation of such results.

3 Additional requirements

3.1 Surface materials for bulkheads and ceilings and similar exposed surfaces

In case there is a requirement of maximum gross calorific value (e.g. 45 MJ/m2) for a product, the method specified in standard ISO 1716: 1973 is recommended for determining the gross calorific value.

3.2 Floor coverings and primary deck coverings

3.2.1 A primary deck covering is the first layer of a floor construction which is applied directly on top of the deck plating and is inclusive of any primary coat, anti-corrosive compound or adhesive which is necessary to provide protection or adhesion to the deck plating. Other layers in the floor construction above the deck plating are floor coverings.

3.2.2 Where a floor covering is required to be low flame-spread, all layers shall comply with part 5. If the floor covering has a multilayer construction, the Administration may require the tests to be conducted for each layer or for combinations of some layers of the floor coverings. Each layer separately, or a combination of layers (i.e. the test and approval are applicable only to this combination), of the floor covering shall comply with this part. When a primary deck covering is required to be not readily ignitable and is placed below a floor covering, the primary deck covering shall comply with part 6. When the primary deck covering is also the exposed surface, it shall comply with this part. Primer or similar thin film of paint on deck plating need not comply with the above requirements of part 6.

3.3 Combustible ventilation ducts

3.3.1 Where combustible ventilation ducts are required to be of material which has low flame-spread characteristics, the surface flammability test procedure and criteria for lining and ceiling finishes according to resolution A.653(16) shall be applied for such ducts. In case homogeneous materials are used for the ducts, the test shall apply to outside surface of the duct, whilst both sides of the ducts of composite materials shall be tested.

3.4 Insulation materials for cold service systems

Where the exposed surfaces of vapour barriers and adhesives used in conjunction with insulation, as well as insulation of pipe fittings, for cold service systems are required to have low flame-spread characteristics, the surface flammability test procedure and criteria for linings and ceilings according to resolution A.653(16) shall be applied for such exposed surfaces.

3.5 Other references

Part 2 of this annex is also applicable to surface materials.

APPENDIX

INTERPRETATION OF RESULTS
Evaluating unusual test specimen behaviour
(see paragraph 2.2 of this part)

	Unusual behaviour	Guidance on classification
1	Flashing, no steady flame	Report furthest progress of flame and time, and whether or not flash is on centerline. Classify on basis of the data.
2	Explosive spalling, no flashing or flame	Accept material as passing test.
3	Rapid flash over surface, later steady flame progress	Report result for both flame fronts but classify on basis of worst performance for each of the four test parameters in the two burning regimes.
4	Specimen or veneer melts and drips off, no flame	Report behaviour and extent of advance on specimen.
5	Explosive spalling, and flame on exposed part of specimen	Report explosions and classify on basis of flame progress irrespective of whether above or below centerline.
6	Specimen or veneer melts, burns, and drips off	Reject material regardless of criteria. For floor covering, no more than 10 burning drops are acceptable.
7	Pilot flame extinguished	Report occurrence, reject data and repeat test.
8	Heat release signal after test and re-insertion of dummy specimen remains at a higher or lower level than initial stabilizing level.	Reject data and stabilize the equipment, then repeat test.
9	Very short ignition delay on carpets or non-rigid specimens	Could be caused by pile extension above holder surface, reducing space to pilot flame. Repeat with shims as required by procedure in paragraph 8.1.1 of the Annex to resolution A.653(16).
10	Specimen breaks up, and falls out of holder	Report behaviour, but classify on basis of worst performance with and without specimen restraint in paragraph 8.3.2 of the Annex to resolution A.653(16).
11	Substantial jetting combustible pyrolysis gases from specimen, adhesive or bonding agents	Reject material.
12	Small flame remaining along the edge of specimen	Report behaviour and terminate the test 3 min after flaming on exposed surface of specimen ceased.
