What is a Humidifying Bottle Performance Tester?

The Paper Gypsum Board Fire Stability Tester is a specialized laboratory instrument for evaluating the fire resistance of gypsum boards and other building or decorative materials. By applying controlled heat and loads, it quantitatively measures the time until sample failure under high-temperature conditions, providing objective data for material safety and certification purposes.

Application

Building Materials Testing and Certification

Testing institutions use this equipment to perform performance testing on fire-resistant materials such as gypsum boards, ensuring that products meet the requirements of standards such as GB/T9775-2008 and ISO6308. and providing internationally recognized test data for export products.

Product Development and Quality Control

Manufacturers optimize product formulations and processes through testing, for example, analyzing the impact of different inorganic fire-resistant fiber content on fire resistance performance, thereby enhancing product competitiveness.

Quality control is implemented during the production process to ensure that each batch of products meets fire safety standards.

Building Fire Protection Design and Safety Assessment

Architects and designers select materials with excellent fire resistance based on test results, for example, prioritizing gypsum boards with fire stability ≥30 minutes in high-rise buildings to improve the overall fire safety rating.

Fire safety experts use test data to assess building fire risks and develop targeted fire protection measures.

Parameters

Test Procedures

Sample Preparation: Cut the sample to the specified dimensions (e.g., 300 mm long × 50 mm wide), and process it under specified environmental conditions, such as drying to constant weight.

Sample Installation: Suspend the sample between two flame nozzles using support rods, with the nozzles perpendicular to the sample surface. Simultaneously, suspend a specified load from the lower end of the sample.

Ignition and Temperature Measurement: Ignite the burner, using liquefied petroleum gas as the heat source. Measure the temperature using a thermocouple at a specified distance from the sample surface (e.g., 5 mm).

Temperature Control: Adjust the temperature to (800 ± 30)℃ within 3 minutes, and maintain this temperature throughout the test.

Observation and Recording: Start timing from the moment the sample is exposed to the flame until it breaks or fails. Record the time it takes for each sample to burn through, using the minimum time among five samples as the fire resistance stability of that group of samples.

Working Principle

The Paper-Faced Gypsum Board Fire Stability Tester evaluates the behavior of gypsum boards under fire exposure by simulating fire scenarios with different temperatures and heat sources. Its core system typically consists of a heating furnace, a temperature control system, a specimen support system, and a measurement system.

Heating furnace:

The heating furnace generates high temperatures through electric heating or combustion devices to simulate the thermal radiation and temperature conditions of a real fire. Its temperature range is generally adjustable to meet different testing standards.

Temperature control system:

Equipped with high-precision temperature sensors and controllers, this system ensures that the furnace temperature follows the preset test profile. The stability of temperature control directly determines the accuracy and repeatability of the test results.

Specimen support system:

This system is used to securely fix the gypsum board specimen, ensuring it remains in the correct position throughout the test and simulates its actual installation state in building structures. The support structure is usually adjustable to accommodate different specimen sizes.

Measurement system:

The measurement system includes multiple sensors for recording parameters such as heat transfer, temperature variation, and flame propagation. By analyzing temperature rise, structural damage, and flame spread rate, the system provides detailed data to evaluate the fire resistance performance of the gypsum board.
