The Glove Thermal Insulation Tester is a precision instrument designed to evaluate the thermal insulation performance of glove materials when exposed to high temperatures. By measuring the temperature rise on the glove surface during controlled contact with a heated brass cylinder, the system provides accurate, repeatable data to assess the protective capabilities of heat-resistant gloves in compliance with international standards.

Application

The tester is primarily used in the following scenarios:

Evaluating thermal resistance of household and industrial gloves

Assessing materials used in automotive, kitchen, and industrial safety gloves

Supporting R&D and quality control departments for heat-protective materials

Ensuring compliance with manufacturing specifications and safety regulations

Standards

The tester complies with and supports testing according to:

BS 6526:2002 – Household Oven Gloves Specification and Test Methods

ISO 12127 – Protective Gloves for Thermal Hazards (Reference Method)

EN 407 – Protective Gloves Against Thermal Risks

ASTM F1060 – Standard Test Method for Thermal Insulation of Materials

ISO 188 – Rubber, Vulcanized or Thermoplastic – Accelerated Ageing and Heat Resistance

Test Procedures

Preparation

Sample Preparation: Fix the glove onto the test fixture, ensuring the sample diameter meets the standard (typically 70 mm).

Equipment Check: Verify power supply, sensors, and heating elements are functioning properly.

Operation

Place Sample: Position the glove on the polyethylene mounting plate equipped with thermocouples connected to the temperature recording device.

Heating Test: Lower the preheated brass cylinder onto the sample and measure the temperature rise over a set duration.

Record Data: Monitor and record the glove’s internal temperature in real-time to calculate thermal insulation performance.

Precautions

Safety: Ensure operators maintain a safe distance from high-temperature components to prevent burns.

Equipment Maintenance: Regularly inspect sensors and heating devices to maintain test accuracy and reliability.

Maintenance Information

Clean thermocouples, sensors, and brass surfaces regularly to prevent measurement errors.

Inspect servo motors and moving parts monthly for smooth operation.

Verify calibration of sensors periodically to ensure accurate temperature readings.

Check the HMI and PC interface functionality to maintain data integrity.

Ensure protective plates and cylinders move freely without obstruction.

Conclusion

The Glove Thermal Insulation Tester provides precise and automated evaluation of glove heat resistance. With servo-controlled brass cylinder release, temperature-accurate sensors, and real-time data acquisition, the system ensures reliable, repeatable, and safe testing of thermal insulation properties for protective gloves in laboratories and industrial applications.
