Touch Screen CPAI84 Flooring Material Flame-resistant Tester
This apparatus is used to evaluate flame resistance of fabric and
other pliable material in camping tentage.
Application scope: for flame-resistant materials :flooring material
Standard:GB/T 11049-2008,CPAI-84:1995 -clause 5 Flammability Test Method, Flooring Material
Specification:
This Flooring Material Test Chamber consists of an open-top hollow
cube made of non-combustible material with inside dimensions 305mm
by 305 mm by 305mm and a minimum of 6 mm wall thickness. The flat
bottom of the box is made of the same material as the sides and
easily removable. The sides are fastened together with screws or
brackets and taped to prevent air leakage into the box during use.
Supporting Frame:
A steel palte,230mm by 230mm,6 mm thick with an 200 mm diameter
hole in its center and a 25 mm by 25mm by 1.5 mm thick shim affixed
to the underside of each corner, to support the material above the
floor of the chamber during the course of the test. The edge of the
supporting frame must be kept clean.
Test Procedure:
1.Place the test chamber in the draft-protected environment (hood
with draft off) with the bottom plate in place and the supporting
frame centered in the bottom of the chamber,shimmed side down.
2.Punch a 6 mm-diameter hole in the center of the specimen of
flooring material
3.Place the specimen on the supporting frame in the position in
which it will be used, exercising care to keep the specimen
horizontal and flat.
Place the flattening frame on the specimen and position a
methenamine tablet on one of its flat sides with its edge within 3
mm of the hole in the center of the specimen.
4.Ignite the tablet by touching a lighted match or an equivalent
igniting source carefully to the top of the tablet.
5. Continue each test until the last vestige of flame or glow
disappears (this is frequently accompanied by a final pull of
smoke) or the flaming or
smoldering has approached within 25 mm of the edge of the hole in
the flattening frame at any point.
6.When all combustion ahs ceased, ventilate the hood and measure
the shortest distance between the edge of the hole in the
flattening frame and the damaged area. Record the distance measured
for each specimen.
7.Remove the specimen from the chamber and remove any burn residue
from teh chamber floor. Before proceeding to the next tst, the
chamber fllor must be cooled to normal romm temperature or replaced
with one that is at normal romm temperature.
