Sole heat resistance testing machine

Основные виды применения:

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.

Reference standard:

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

Принцип испытания:

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℃。
