Requirements for ventilation dampers for tunnels

Requirements for ventilation dampers for tunnels

When a tunnel exceeds a given length, it is compulsory to install mechanical ventilation systems that should remain operative in the event of fire in order to remove smoke and hot gases. Regulations are somewhat ambiguous in relation to the type of requirements and specific conditions that may be requested from ventilation systems during a fire, considering that it is not necessary to treat them like fire doors in building compartmentalization. This report aims to identify the criteria to be followed for a harmonised assessment of these products and for their certification.

Conditions for using a range of synthetic pipes in wet fire-fighting systems

Conditions for using a range of synthetic pipes in wet fire-fighting systems

A manufacturer of multilayer polymer pipes and fittings wants to clarify the kind of situations where they can be safely used to feed sprinkler installations and hose reel cabinets, defining appropriate design and execution criteria. A plan of inspections and tests will assess the degree of adequacy of these pipes to the different risk levels defined by EN 12845 standard and by the fire safety regulations.

Fire resistance of cross-laminated timber panels

Fire resistance of cross-laminated timber panels

CLT panels assume structural functions in the building, therefore designers must know their performance in case of fire. But in the case of cross-laminated wood, the standard carbonization rates of conventional wood can not be used to calculate fire resistance values. Therefore, it has been necessary to design and carry out a specific testing campaign to obtain the actual carbonization rates of the CLT panels under evaluation.

Evaluation of fire protection systems for structures

Evaluation of fire protection systems for structures

Development of the EU-level regulatory and functional requirements for evaluating different products and technologies to protect different types of structures (steel, concrete, compound or other materials) against fire using intumescent paints, mortars or boards. It is part of ITeC’s contribution to the European working group that develops the ETAG 018 guideline that is the reference document for evaluating these protection systems.

Assessment of the performance of a fire-fighting system for unattended petrol stations

Assessment of the performance of a fire-fighting system for unattended petrol stations

Assessment of the functional requirements of an automatic fire detection and extinguishing system designed to operate at unattended gas stations where it has to trigger itself in the event of a flame in the refuelling zone. The different operation choices (pneumatic and mechanical) and position choices (surface or pit) are contemplated.

Assessment of fireproofing solutions for pipe penetrations

Assessment of fireproofing solutions for pipe penetrations

The fire resistance of walls and floor slabs is compromised in those points where pipes go through, so if it is critical to guarantee their integrity in case of fire, specific sealing elements such as intumescent collars must be used. The evaluation has required to determine on a case-by-case basis how much fire resistance time can be expected according to the type of collar, material and geometry of the pipe, and components and geometry of the wall or floor.

Behavior of intumescent products exposed to weather

Behavior of intumescent products exposed to weather

The manufacturer of an intumescent fabric for fire protection of cables wants to validate that it can be marketed as suitable for outdoor use (Type X in EOTA nomenclature). For this purpose, a battery of tests has been designed to simulate the effects of 10 years of exposure to UV radiation, rain and temperatures from -20ºC to 70ºC, checking afterwards how the product reacts in case of fire.

Fire reaction of the skylights of industrial buildings

Fire reaction of the skylights of industrial buildings

When skylights are added on the top of an industrial building for lighting purposes, they become points of discontinuity in the roof that can be problematic in case of fire. The Spanish Fire Safety Regulation for Industrial Facilities requires that the skylight material must prove a certain type of fire reaction, but with a series of caveats that have prompted a manufacturer to request from ITeC a precise specification of the kind of performance that will be legally required from their products.

Assessment of fire-fighting systems for professional kitchens

Assessment of fire-fighting systems for professional kitchens

Development of regulatory and functional requirements for the evaluation of fire detection and extinguishing systems for kitchens for hotels, restaurants and catering. These safety measures are compulsory according to the Spanish Building Code in kitchens according to their power consumption and the intended use of the building or the facility.

Definition of a battery of tests for a product for passive fire protection of floor slabs

Definition of a battery of tests for a product for passive fire protection of floor slabs

Elaboration of a document of technical specifications according to ETA Guide 018-3 for testing the fire resistance of a concrete and sheet metal floor where a passive protection mortar has been sprayed on. With this document, the manufacturer can request quotes from different laboratories with the certainty that the tests have been precisely defined and they follow the requirements for a subsequent product certification.
