3500W NBS Plastic/ Rubber Smoke Density Testing Machine ISO
5659-2:2006
Product Description
(note: Other unspecified or conflicting GB/8323.2-2008 standards
prevail)
The plastic burning smoke density tester is a new test equipment
for measuring smoke density, which is based on the technical
conditions stipulated in the national standard GB8323.2-2008, which
is suitable for measuring the specific light density of smoke
produced in the combustion of plastics, and the maximum light
density is the test result. It is used to assess the smoke
performance of plastics under specified conditions. Conforms to
GB8323.2-2008 plastic-smoke Generation-Part II: Single-chamber
method for the determination of smoke density test method and
ISO5659.2-2006 "plastic-Smoke Generation-Part II: Single-chamber
method for the determination of light density". The whole
instrument consists of a closed test chamber, a photometer
measuring system, a radiation cone, a combustion system, a igniter,
a test box, a stent, a temperature measuring instrument, and a
smoke density test software; the circuit is developed with
single-chip microcomputer, with high technical content and stable
performance. This instrument is suitable for all plastics, also
applicable to other materials evaluation (such as rubber, textile
cover, paint, wood and other materials), the plastics industry,
solid materials industry, production plants and research
laboratories widely used.
