Extended application of the results of fire resistance and/or smoke dispersion control tests for doors, locking systems and opening windows and their construction components

Tipo: Extended application

Standard: UNI EN 15269

Clienti:

This family of standards, which is quite numerous, gives indications on how products can (or cannot) be modified after the test beyond the scope stated in the test standard.

DIRECT FIELD OF APPLICATION

Some modifications automatically allowed to the manufacturer, are those inserted in the DIRAP, the direct field of application of the results, inserted in the test standard and normally included in the product classification reports. For example, the reduction (or possible increase) of measures, the increase in thickness, the eventual possibility of changing from a flexible support (plasterboard) to a rigid one (masonry). All these variants, listed just to give an idea, can be linked to specific parameters related to the component materials rather than to the test results themselves. As an example, a wooden door tested on masonry can be installed on plasterboard and vice versa, a metal door needs two separate tests, and so on. However, these changes do not affect the construction components, such as locks, hinges and much more.

But how can a door manufacturer change locks or hinges?

Sure, just make another test. But the test is time-consuming and expensive and it must be considered that doors can have many variations required. The standardiser has therefore introduced some very important tools to manage the possibility of making variants without carrying out a new test. In the European standards system there is the EN15269family of standards which deals with the extended application of test results for fire resistant and smoke-proof doors.

STANDARDS

The main standards are: - EN 15269-1 general requirements; - EN 15269-2 steel doors; - EN 15269-3 wooden doors; - EN 15269-7 sliding doors; - EN 15269-20 smoke-tight doors. The standards prEN17020-1, prEN17020-2, prEN17020-3, prEN17020-4are being studied with regard to the durabilitycharacteristic. The EN15269family of standards contains, diversified by areas (fire and smoke), materials (wood or metal) and types (sliding or swinging) a series of rules that allow changes to be made with respect to the tested sample.

THE PROCEDURE

Generally speaking, a door manufacturer for a modification of materials or geometries, proposes the modification to the laboratory that tested the door, possibly adding further test evidence required by EXAP. In case of presence of more than one test report, in accredited laboratories, it is the manufacturer's faculty to choose indifferently one of the test laboratories that issued the reports that will be used as supporting evidence in the EXAPto study and issue the extension and consequently to draw up the extended classification report, as specified in point 5.3.1 of EN15725. This allows for product modifications that also include the interchangeability of construction components in the area of fire and smoke-proof doors.

HPS

When drafting EXAPs, the HPS - Hardware Performance Sheet, drawn up in accordance with EN16035, can be very useful. It can be useful precisely to give the laboratory that will make the EXAP the possibility to choose only the test evidence useful for that specific work. The HPS is a tool reserved for construction components, what we commonly call accessories, such as hinges, locks, door closers, etc... In CHEMOLLI FIREwe have assisted several clients to request rather complex EXAP, probably otherwise impossible, thanks to the following factors:

• familiarity with the material;
• an extensive database of previous evidence in which to identify useful evidence;
• within this, about thirty evidence in our name to draw from;
• a network of contacts with which to attempt to obtain authorisation to use such evidence.
