FAQ

(1)What materials can be tested with a smoke density tester?

This instrument is mainly used for building materials, textile materials, plastics, and other solid combustible materials. It evaluates smoke generation characteristics during combustion and provides data for material safety assessment and research.

(2)What does smoke density measurement indicate about a material?

Smoke density testing reflects the amount of smoke produced during combustion by measuring changes in light transmission. The results help researchers understand combustion behavior and compare the smoke generation performance of different materials.

(3)Which standards are commonly used for this smoke testing method?

The instrument is designed according to GB/T 8627 for building material smoke density testing and ASTM D2843 for smoke density evaluation of plastics, depending on the material type and testing requirements.

(4)How does the instrument measure smoke density?

During combustion, generated smoke reduces the amount of light passing through the test chamber. The photoelectric system detects these changes and converts them into smoke density values ranging from 0% to 100%.

(5)What should laboratories consider when selecting smoke density testing equipment?

Laboratories should consider applicable standards, measurement range, optical accuracy, combustion control system, smoke exhaust capability, and data analysis functions to ensure reliable and repeatable material evaluation.
