ECE R118 Annex 7, NF P92-505 Thermal Radiant Melt Drop Testing Machine

ECE R118 Annex 7, NF P92-505 Thermal Radiant Melt Drop Testing Machine

Description:

This machine is suitable for test thermal melt material, in order to find out droplet combustion characteristics of building materials under the influence of the heat source or not. The experiment is material specimen under radiant heat source of the upper radiator under the specified conditions:
1) combustion of released gas;
2) drop of burning or non-burning drops;
3) combustion of fiber cotton.

Standard:

ECE R118 Annex 7-TEST TO DETERMINE THE MELTING BEHAVIOUR OF MATERIALS,

NF P 92-505 Dripping test with electrical radiator, used for melting materials

Specification:

1. Heat source:
The source of heat is an electric radiator with a useful output of 500W. The radiating surface is made of a transparent quartz plate with a diameter of 100mm; it is heated by coiling electric resistance wire, and on a spiral groove of refractory bracket.

2. Specimen holder:
The support for the samples is a metallic ring, on top of this support a grill, made of stainless steel-wire, is placed with the following dimensions: interior diameter 118mm, dimension of the holes 2.10mm square, diameter of the steel-wire 0.70mm.

3. Droplet collector:
The receptacle is a cylindrical tube with an interior diameter of 118mm and a depth of 12mm. The receptacle is filled with cotton wool.
