Peutz is the only consultancy firm with its own Fire Safety Laboratory. The laboratory is accredited by the Dutch Accreditation Council (registration number L334) for determining the fire resistance of walls, doors, and ceilings, in accordance with harmonized European standards and NEN 6069. It is also accredited for determining the reaction to fire of most construction products. Peutz is recognized as a Notified Body by the Ministry of the Interior and Kingdom Relations under number NB 2264.
Fire resistance testing
Fire resistance indicates how long a structure can withstand fire. To determine this, we place the construction element in a furnace measuring 4 meters wide and 3 meters high. For horizontal constructions, the (tiltable) furnace is used in a horizontal position, and the element is placed on top. The temperature in the furnace is then increased according to a standardized fire curve. After 30 minutes, the temperature exceeds 800 °C, and after one hour, it reaches nearly 1000 °C. Other fire curves (such as the external fire curve or the hydrocarbon/HC curve) can also be used. During the test, we assess surface temperature, radiation, and flame tightness.
Based on the test results, Peutz can also translate the achieved fire resistance into the European classification system, in accordance with EN 13501-2.
Reaction to fire testing
Reaction to fire focuses on the flammability and the amount of heat and smoke produced during combustion of a material.
For classes B to E (and for pipe insulation classes BL to EL), the reaction to fire is determined using two tests: the Small Flame Test and the Single Burning Item (SBI) Test. These tests can be performed in Peutz’s Fire Safety Laboratory.
The results are expressed in the fire class or Euroclass, and this classification (EN 13501-1) can also be provided by Peutz.
Reliable results
Accreditation in accordance with NEN-EN-ISO/IEC 17025 (RvA registration number L334) and designation as a Notified Body (NB 2264) ensure that qualified test spaces, facilities, and methods are used.
The results of an accredited fire test conducted in the Fire Safety Laboratory are therefore undisputed and valid throughout all EU Member States. Our test results can also be used for CE marking of construction products.
Guideline for expert assessments by Efectis Peutz
Recently, the guideline for how we prepare expert assessments has been updated. This guideline, developed in collaboration with Efectis, ensures quality and provides transparency about the standards our assessments meet.
