Fire tests on building materials and structures — 
Part 22: Methods for determination of the fire resistance of non-load bearing elements of construction 
This standard has been superseded by the current BS EN 1634-1, but it has been in conjunction with BS 476-20 which describes the general principles for these retained based on legitimate need for the standards within non-EU markets. 

Scope 
This Part of BS 476 describes procedures for determining the fire resistance of non-load bearing elements of building construction when subjected to the heating and pressure conditions specified in BS 476-20.

Carry out the test in accordance with BS 476-20 and make any observations on the behaviour of the specimen, including the mode of failure in the event of collapse. 

The result shall be stated in terms of the elapsed time to the nearest minute, between the commencement of heating and the time of failure 

Samples shall be tested from both sides, i.e. two specimens

If testing is carried out from one side only, i.e. one specimen, the reason for this shall be clearly stated in the report. 

Determination of the fire resistance of glazed elements
Integrity.  Monitor the unexposed face of the specimen for evaluation of the integrity in accordance with clause 9 of BS 476-20:1987.

Insulation.  Measure the temperature rise of the unexposed face for evaluation of the insulation in accordance with clause 9 of BS 476-20:1987 for both the mean temperature rise and the maximum temperature rise.

Lateral deflection.  Whilst the specimen is not evaluated with respect to either the rate or extent of lateral deflection, monitor the glazing for deflection.

Irradiance.  Monitor the irradiance of the specimen by means of the radiometer in accordance with BS 476-20. 

Determination of the fire resistance of partitions 
Vertical glazed separating elements, partitions with less than 50 % glazing will be tested as partitions. 

Integrity.  Monitor the unexposed face of the specimen for evaluation of the integrity in accordance with clause 9 of BS 476-20:1987. 

Insulation.  Measure the temperature rise of the unexposed face for evaluation of the insulation in accordance with clause 9 of BS 476-20:1987 for both the mean temperature rise and the maximum temperature rise.

Deflection.  Monitor the maximum deflection of the specimen. 

Irradiance.  Monitor the irradiance of the unexposed face.

Determination of the fire resistance of fully insulated door-sets and shutter assemblies 
Integrity.  Monitor the temperature rise of the fixed frame components of the door or shutter assembly.

Insulation.  Measure the temperature rise of the unexposed face for evaluation of insulation in accordance with clause 9 of BS 476-20:1987, for both the mean temperature rise and the maximum temperature rise.

Monitor the temperature rise of the fixed frame components of the door or shutter assembly.

Lateral deflection.  Monitor the lateral deflection of the specimen. 

Determination of the fire resistance of partially insulated door-sets and shutter assemblies 
Integrity.  Until the criteria for insulation failure occurs, monitor the unexposed face of the specimen for evaluation of integrity in accordance with clause 9 of BS 476-20:1987.

Insulation. Measure the temperature rise of the unexposed face for evaluation of insulation in accordance with clause 9 of BS 476-20:1987, for both the mean temperature rise and the maximum temperature rise 

Monitor the temperature rise of the fixed frame components of the door or shutter assembly

Lateral deflection.  Monitor the lateral deflection of the specimen. 

Irradiance.  Monitor the irradiance by means of the radiometer described in BS 476-20

Determination of the fire resistance of uninsulated door-sets and shutter assemblies 
Integrity.  Monitor the unexposed face of the specimen for evaluation of integrity in accordance with clause 9 of BS 476-20:1987. 

Insulation.  Monitor the temperature rise of the unexposed face in accordance with clause 9 of BS 476-20:1987, for both the mean temperature rise and the maximum temperature rise.

Monitor the temperature rise of the fixed frame components of the door or shutter assembly.

Lateral deflection.  Monitor the lateral deflection of the specimen. 

Irradiance.  Monitor the irradiance by means of the radiometer described in BS 476-20.
