Shoe Sole Heat Resistance Tester

Principali usi:

The sole heat resistance tester is used to test the heat resistance and temperature insulation performance of finished shoes under high temperature sand and stone heat temperature medium.

Norma di riferimento:

EN ISO 20344, EN ISO 8772-1, GB/T 20991-2007, ANSI, JIS, CSA, GB12017-1989, LD50-1994 and other standards

Product Advantages:

Measures Critical Safety Property: Quantifies the thermal insulation and heat resistance of footwear soles, essential for safety in hot environments.

Standard Compliant: Designed to meet numerous relevant national and international standards for footwear heat resistance and thermal insulation testing.

Simulates Real-World Exposure: Uses a heated sand bath to mimic contact with hot surfaces.

Provides Objective Measurement: Records the actual temperature rise on the inside of the shoe (at the insole).

Controllable Test Temperature: Allows testing at standardized high temperatures (150℃ or 250℃).

Suitable for Finished Shoes: Designed to test complete footwear.

Caratteristiche del prodotto:

Heated sand bath with specific dimensions and minimum sand height.

Heating system capable of heating the sand to controlled test temperatures (150℃ or 250℃).

Temperature control system to maintain the sand bath at the specified test temperature with a certain tolerance.

System for accurately measuring and recording the temperature change on the upper surface of the insole over a specified time (30 minutes), using a copper/copper-nickel thermocouple with a copper disc.

Uses sand of a specific particle size range and volume as the primary heat transfer medium.

May include provisions for using other heat transfer media, such as 5mm steel balls, depending on the specific test standard or configuration.

Fixture or area for placing the finished shoe on the heated sand bath, ensuring good contact.

Robust construction suitable for operating at high temperatures.

Principio di prova:

The sandbox is heated to 150℃， the sand covers the contact point between the sample upper and the sole, and the change of the insole temperature over 30 minutes is recorded, accurate to 0.5℃。
