ISO 5659-2 Laboratory Test Apparatus NBS Plastics Smoke Density Testing Equipment

Introduction:

NBS Plastic Smoke Density Testing Equipment is a test equipment used to measure smoke density according to the technical conditions specified in EN 45545-2, ISO5659.2-2006 and ASTM E662 standards.

This standard applies to the determination of the specific optical density of smoke produced by plastic combustion, with the maximum specific optical density being the test result. The equipment is used to evaluate the smoke performance of plastics under specified conditions.

The whole set of instruments consists of a closed test chamber, a photometric system, a radiation cone, a combustion system, an igniter, a test chamber, a bracket, a thermometer and a smoke density test software; the circuit is developed using a single-chip microcomputer, with high technical content and stable performance.

NBS Plastic Smoke Density Testing Equipment is suitable for all plastics and is also suitable for evaluating other materials (such as rubber, textile coverings, painted surfaces, wood, and other materials). It is widely used in production plants in the plastics industry and the solid materials industry as well as scientific research and testing units.

Reference standard:

• ASTM E 662 Standard test method for specific optical density of smoke generated by solid materials.
• ISO 5659-2 Plastics – Smoke generation – Part 2: Determination of optical density by a single–chamber test.

ASTM E662 smoke density test mode:

25kw/m2 irradiation + flame and 25kw/m2 irradiation + flameless

ISO 5659-2 smoke density test mode:

Mode 1: 25kw/m2 irradiation + flame

Mode 2: 25kw/m2 irradiation + flameless

Mode 3: 50kw/m2 irradiation + flame

Mode 4: 50kw/m2 irradiation + flameless

ASTM E662 test requirements:

This standard is generally cited in NFPA 130, and Ds (1.5) and Ds (4.0) are required

ISO 5659-2 smoke density test requirements:

Generally in EN 45545-2, DIN 5510-2 and BS 6853, each with different requirements.

Main Feature:

• Test chamber is composed of a box, a sample box, a radiation cone, an igniter, a light transmission and measuring device, and other related control devices.
• Test chamber with full-width opening door, allowing easy access for sample loading and chamber cleaning.
• Controls are mounted beside the chamber for convenient operation. They are not obstructed when the door is open.
• Smoke density and temperature are on digital displays for easier use and greater accuracy.
• Safety blow-out panel, easily replaceable, allows for safe operation of the test method.
• Gas measurement ports are provided for optional measurements of toxic gases.
• Cabinet designed with a standard 19" rack, for simple addition of gas analyzers and a chart recorder, and other control units.
• Computer software.
