ASTM D2843 High Precision smoke density tester for Plastic Smoke Obscuration Test

ASTM  D2843 smoke density tester

Product information

The ASTM D2843 smoke density tester is a professional laboratory device designed to evaluate the density of smoke produced by plastic materials during combustion or decomposition. It is widely applicable to various plastic products, including homogeneous plastics, laminated plastics, and foam plastics, in areas such as building materials such as plastic flooring and wall panels, transportation components such as automotive interiors and aircraft cabin panels, consumer products such as electronic device housings and toys, electrical cable insulation, and packaging materials. By simulating controlled combustion conditions, the tester helps manufacturers and engineers compare the smoke generation characteristics of different plastics, ensuring that products reduce the risk of smoke obscuration in potential fire scenarios, thereby improving the safety and compliance of construction, transportation, consumer, and industrial applications. It is an indispensable tool for material fire performance testing.

Standards

ASTM D-2843 - Standard Test Method for Density of Smoke from the Burning or Decomposition of Plastics

Application

This standard is widely used for plastic products in the following areas:

Building Materials: Plastic flooring, wall panels, ceiling panels, insulation materials (such as foam insulation boards), pipes and fittings, window frames, door and window seals, etc. It is used to evaluate the smoke risk of building interior finish materials in fires to ensure compliance with building fire codes.

Transportation: Automotive interior components (such as instrument panels, seat foam, door panels), aircraft cabin materials (such as luggage racks, seat coverings), train or subway car plastic components (such as handles, floor coverings), and ship interior plastic trim. It is used to test the smoke generation of transportation interior materials to improve passenger safety.

Consumer Goods and Electronics: Electronic device casings (such as mobile phone cases, computer cases, appliance panels), furniture plastic components (such as chair legs, cabinet doors), toys (such as plastic building blocks and models), and household appliance plastic accessories (such as refrigerator linings and washing machine casings). It is used to evaluate the smoke characteristics of everyday consumer products in fires to ensure product safety standards.

Electrical and Cable: Cable insulation, wire sheathing, electrical switch boxes, outlet panels, etc., for testing the smoke density of electrical plastic materials to prevent smoke spread in electrical fires.
Packaging and Industrial Materials: Plastic packaging films, industrial containers, protective covers, etc., for evaluation of smoke control in industrial applications.
