Interpretations of Vague Expressions, other Vague Wording and References in the Fire Test Procedure (FTP) Code and Fire Test Procedures Referred to in the Code

Relevant document Paragraph Interpretation or reference
Fire Test Procedure Code
FTP Code, Approval 5.1.6.5 For cases where an unsuccessful test had been conducted prior to the final approval test, the fire test report should include a description of the modifications made to the test specimen that resulted in the successful test.
FTP Code, Approval 5.2.4 Type approval certificates for windows should state which side of the window was exposed to the heating condition during the test.
The certificate should include a reference to optional test(s) such as hose stream test and/or thermo radiation test.
Non-combustibility test
FTP Code, Annex 1 Part 1 2.1 The test exposure need not exceed a 30 min duration.
For the purposes of this Part, ISO 1182:2002 may be used in lieu of ISO 1182:1990.
Smoke and toxicity test
FTP Code, Annex 1 Part 2 2.6.2 Not only the FTIR (Fourier Transform Infrared Spectrometer) method but also other methods such as GC/MS (Gas Chromatography/Mass Spectrometer) which can produce traceable results can be used for the gas analysis.
Test for "A", "B", and "F" class divisions including windows, fire dampers, pipe penetrations and cable transits
FTP Code, Annex 1 Part 3
Resolution A.754(18),
2.1
2.6.2.2
"B" class doors should be fire tested in B class steel bulkheads of dimensions as stated in paragraph 2.4.1 of resolution A.754(18), otherwise approval should be limited to the type of construction in which the door was tested.
FTP Code, Annex 1 Part 3 2.2.1 The minimum bulkhead panel height should be a standard height of the manufactured panel with a dimension of 2.4 mm.
FTP Code, Annex 1 Part 3 3.1 The calcium silicate board described as a dummy specimen specified in paragraph 3.3 of resolution A.653(16) should be used as a standard substrate for adhesives.
FTP Code, Annex 1 Part 3 4.1 Sealing materials used in penetration systems for "A" class divisions are not required to meet non-combustibility criteria provided that all other applicable requirements of FTP Code, part 3, are met.
Resolution A. 754(18) 1.2 The thickness of insulation on the stiffeners need not be same as that of the steel plate.
Resolution A.754(18) 1.6 Doors, windows and other division penetrations intended to be installed in fire divisions made of material other than steel should correspond to prototype(s) tested on a division made of such material, unless the Administration is satisfied that the construction, as approved, does not impair the fire resistance of the division regardless of the division construction.
Resolution A.754(18) 1.7 "B" class constructions should be tested without finishes. For constructions where this is not possible, finishes should be included in the non-combustibility test of the construction.
Resolution A.754(18) 2.8.2 Where testing is conducted on a perforated ceiling system, equally constructed non-perforated ceilings and ceilings with a lesser degree of perforations (in terms of size, shape, and perforations per unit area) may be approved without further testing.
Resolution A.754(18) 9 There exist no expectations that "A" and "B" class fire doors remain functional, in the ability to be opened/closed, during or after the specified test duration.
Resolution A.754(18), Appendix A.I Windows 2.1 The test should be conducted on a window of the maximum size (in terms of both the height and the width) and the type of the glass pane and/or the minimum thickness of the glass pane or panes and gaps, if appropriate, for which approval is sought. Test results obtained on this configuration should, by analogy, allow approval of windows of the same type, with lesser dimensions in terms of height and width and with the same or greater thickness.
Resolution A.754(18), Appendix A.I Windows 5.3 The window should be considered to have failed the hose-stream test if an opening develops that allows an observable projection of water from the stream beyond the unexposed surface during the hose stream test. Gap gauges need not be applied during or after the hose stream test.
Resolution A.754(18), Appendix A.II Fire dampers 2.2.4 The distance between the fire damper and the structural core specified in paragraph 2.2.4 means the distance between the fire damper centre and the structural core.
Resolution A.754(18), Appendix A.II Fire dampers 4 If evaluation of insulation is required, it should prevent a temperature rise at any point on the surface not exceeding 180°C above the initial temperature. The average temperature rise is not relevant.
Resolution A.754(18), Appendix A.III Pipe and duct penetrations 4.1 Penetrations and transits should meet both integrity and insulation criteria.
Resolution A.754(18), Appendix A.IV Cable transits 4.1 Penetrations and transits should meet both integrity and insulation criteria.
Test for surface flammability
FTP Code, Annex 1 Part 5 1 Where a product is approved based on a test of a specimen applied on a non-combustible substrate, that product should be approved for application to any non-combustible substrate with similar or higher density (similar density may be defined as a density ≥ 0.75 × the density used during testing) or with a greater thickness if the density is more than 400 kg/m3. Where a product is approved on the basis of a test result obtained after application on a metallic substrate (e.g. thin film of paints or plastic films on steel plates), such a product should be approved for application to any metallic base of similar or higher thickness (similar thickness is obtained as a thickness ≥ 0.75 × the thickness of metallic substrate used during testing).
Resolution A.653(16) 7 Where a product is approved based on a test of a specimen applied on a non-combustible substrate, that product should be approved for application to any non-combustible substrate with similar or higher density (similar density may be defined as a density ≥ 0.75 × the density used during testing) or with a greater thickness if the density is more than 400 kg/m3. Where a product is approved on the basis of a test result obtained after application on a metallic substrate (e.g. thin film of paints or plastic films on steel plates), such a product should be approved for application to any metallic base of similar or higher thickness (similar thickness is obtained as a thickness ≥ 0.75 × the thickness of metallic substrate used during testing).
Resolution A.653(16) 7.3 Vapour barriers used in conjunction with insulation should be tested without any other components of "A" or "B" class constructions that will shield the barrier being tested from the radiant panel.
Resolution A.653(16) 8.3.1 In the first line of the first sentence, the word "or" should read "of".
Resolution A.653(16) 10 The sentence should be understood to mean: "Materials giving average values for all of the surface flammability criteria as listed in the following table ... (etc.)."
Qsb means an average of three values of average heat for sustained burning, as defined in paragraph 9.3.
Test for primary deck coverings
FTP Code, Annex 1 Part 6 2.1 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.
FTP Code, Annex 1 Part 6 2.2 Fire test procedure
The test may be terminated after 40 min.
