Wire Fire Resistance Test Machine, IEC 60331

Description:

Fire-resistant cable refers to the cable that can keep a safe running time in the case of flame combustion.

TESTECH Fire Resistance Tester is designed according to the requirements of IEC60331-11.and used to obtain the refractory characteristics of a fire resistant cable or optical cable under flame conditions.

Standards:

• IEC 60331 Part 11

• IEC 60331 Part 21

User' s Experience:

1. This cabinet is made of stainless steel, anti-smoke and gas corrosion.

2. The control system is designed with a high degree of automation, automatic ignition, temperature and time digital display, convenient to observe and record, stable and reliable.

Main Features:
