NBS Plastic/ Rubber Smoke Density Testing Machine SL-FL17

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.
