ISO 13506-2: 2017 on the BTTG male manikin (RALPH)
8 second flame exposure time

Testing was undertaken on the “male” heat sensing manikin known as RALPH (Research Aim Longer Protection
against Heat) developed at BTTGTM.

This version of RALPH together with the associated test facility has been built
to comply with ISO 13506-1: 2017 and ISO 13506-2: 2017.
RALPH has a total of 123 sensors distributed over the head, torso, legs and arms monitor the temperature on
the surface of the manikin during a test. (The hands and feet of the manikin are not sensored).

From the temperatures recorded predictive percentage burn injury at Pain, 1st, 2nd and 3rd degree levels are
calculated using the Takata and Stoll skin model as specified in Annex C of ISO 13506-2: 2017.

During a test the manikin is challenged by a flame engulfment apparatus consisting of 12 burners (in two tiers of
six) surrounding the manikin in a hexagonal pattern. The manikin is placed at the centre of the hexagonal pattern.
The lower set of six burners are pointed at the legs and lower body of the manikin whilst the upper set of six
burners are pointed at the upper body and head.

The tests were performed under the following conditions:

Mean heat flux: 84kW/m² ± 5% (i.e. 79.8kW/m² – 88.2kW/m²)
Flame exposure time: 8 seconds
Data acquisition time: 120 seconds
