This International standard describes a protocol for the verification and validation of building fire

evacuation models. The present document mostly addresses evacuation model components as they are

in microscopic agent-based models. Nevertheless, the user of this protocol may adopt it (entirely or part

of it) for macroscopic models if the model is able to represent the components under consideration.

The area of application of the evacuation models discussed in this document includes performancebased

design of buildings and the review of the effectiveness of evacuation planning and procedures.

The evacuation process is represented with evacuation models in which people movement and their

interaction with the environment make use of human behaviour in fire theories and empirical

observations. The simulation of evacuation is represented using mathematical models and/or

agent-to-agent and agent-to-environment rules.

The area of application of this standard relates to buildings. This document is not intended to cover

aspects of transportation systems in motion (e.g. trains, ships) since specific ad-hoc additional tests may

be required for addressing the simulation of human behaviour during the evacuation in these types of

systems (Guillaume and Thiry-Muller, 2018).

This document includes a list of components for the verification and validation testing as well as a

methodology for the analysis and assessment of accuracy associated with evacuation models. The

procedure for the analysis of acceptance criteria is also included.

A comprehensive list of components for testing is presented in this document since the scope of the

testing has not been artificially restricted to a set of straightforward basic set of applications.

Nevertheless, the application of evacuation models as a design tool may be affected by the numbers of

variables affecting human behaviour under consideration. A high number of influences might hamper

the acceptance of the results obtained given the level of complexity associated with the results. Simpler

calculation methods such as macroscopic models, capacity analyses or flow calculations are affected to a

lower extent by the need to aim at high fidelity modelling. In contrast, more sophisticated calculation

methods (i.e. agent-based models) rely more on the ability to demonstrate that the simulation is able to

represent different emergent behaviours. For this reason, the components for testing are divided into

different categories so that the evacuation model tester can test an evacuation model both in relation to

the degree of sophistication embedded in the model as well as the specific scope of the model

application.

In Annex A, a reporting template is provided to provide guidance to users regarding a format for

presenting test results and exemplary application of verification and validation tests are presented

in Annex B.

This part of ISO 13784 specifies a test method for evaluating the reaction-to-fire performance of thermal insulating sandwich panel building systems for large rooms and the resulting flame spread on or within the thermal insulating sandwich panel building construction when it is exposed to heat from a simulated internal fire with flames impinging directly on its internal corner. The test method is not intended for evaluating a product's fire resistance.

This part of ISO 13784 is applicable to both freestanding and self-supporting, and frame-supported, thermal insulating sandwich panel systems, but only to wall and ceiling or roof constructions.

This document gives requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes.

NOTE 1 All pressures are expressed in megapascals and in bar. 1 MPa = 10 bar.

Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see clause 8).

Type A (Rubber) hoses are intended for use at a minimum temperature of -20 °C and Type B (Thermoplastics) hoses are intended for use at a minimum temperature of -10 °C.

NOTE 2 Hoses for use at temperatures lower than those specified above can be supplied by agreement between the manufacturer and purchaser. In this case, the low temperature flexibility test (see 6.3) should be carried out at the specified temperature.
