6. Fire protection
6.1 Fire behavior classification
Fire behavior of construction materials, e.g. piping systems and isolation materials, have been defined in fire classification classes
as per DIN 4102-1. Construction materials are classified as combustible and non-combustible materials. According to DIN 4102-1
and EN 13501-1, PP, and thus Wavin AS+, is listed as B2 (normally flammable) or according European standard D S
3
do.
In line with European standardization, the fire classification
classes as per DIN 4102-1 are translated into the European
DIN EN 13501. The accreditation is based on the standar-
dized Singl-burning-Item-Test (SBI) in conformity with DIN
EN 13823.
6.2 Fire resistance classification
The fire resistance classification provides the fire resistance
duration of a specific construction material.
