ISO 5658-2 Response to Fire Tests - Spread of Flame - Part 2: Lateral Spread on Buildings and Transport Products in Vertical Configuration

The ISO 5658-2 standard, developed by the International Standards Organization (ISO), describes a test method for measuring the lateral spread of flame along the surface of a vertically oriented product sample.

This standard provides data suitable for comparing the performance of essentially flat materials, composites or assemblies used as exposed surfaces of walls in buildings and transportation vehicles such as ships and trains in general. Some profiled products, such as pipes, are also tested in accordance with this test method under specified mounting and fixing conditions.

This test method is applied to characterize and determine the properties of materials, products or assemblies in response to the radiated heat of a pilot flame under controlled laboratory conditions.

However, it is not appropriate to use the ISO 5658-2 standard alone to identify or assess the fire hazard or fire risk of materials, products or assemblies under actual fire conditions.

In fact, the ISO 5658 standard consists of three parts under the heading "Reaction to fire tests - Spread of flame":

• Part 1: Guidance on the propagation of flames (technical specification)
• Part 2: Lateral sprawl in vertically placed building products
• Part 4: Medium scale test for vertical spread of flame from vertically oriented specimen

Briefly, this standard describes the development of standard tests for flame propagation and the theory of flame propagation for various aspects. The ISO 5658-2 standard provides a simple test method in which the horizontal spread of flame on a vertical sample is determined for comparison purposes. This method is widely used especially in research and development and quality control studies.

A fire event is a complex event whose behavior and effects depend on a number of interrelated factors. The behavior of materials and products varies depending on the characteristics of the fire, the method of use of the materials and the environment to which they are exposed.

Our organization provides test services for measuring the lateral spread of flame along the surface of a vertically oriented product sample within the scope of ISO 5658-2 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors. also gives.
