1,Overview (Note: Other unspecified or conflicting information shall prevail in ASTM E662-2014 standard)

The plastic combustion smoke density tester is a new type of testing equipment developed based on the technical conditions specified in the American standard ASTM E662-2014. It is suitable for measuring the specific optical density of smoke generated during plastic combustion, and uses a high specific optical density as the test result. It is used to evaluate the smoking performance of plastics under specified conditions. The entire instrument consists of a closed test chamber, a photometer measurement system, a radiation cone, a combustion system, an igniter, a test box, a bracket, a temperature measuring instrument, and smoke density testing software; The circuit is developed using a microcontroller, with high technical content and stable performance. This instrument is suitable for all plastics and can also be used for the evaluation of other materials (such as rubber, textile coverings, painted surfaces, wood, and other materials). It is widely used in production factories and research and testing units in the plastic and solid materials industries.

2,Main technical indicators and working conditions

The main technical indicators and working conditions of this equipment are fully developed based on the technical conditions specified in the American standard ASTM E662-2014, and comply with the standard test method for smoke specific optical density generated by solid materials in ASTM E662-2014. The performance evaluation, acceptance conditions, and acceptance criteria of this equipment are based on the various clauses, technical indicators, and technical requirements specified in the above standards.
