ISO12127 Thermal conductivity tester

Product introduce

The ISO 12127 thermal conductivity tester evaluates protective clothing materials under high-temperature contact conditions (100°C–500°C) using a heated cylinder and calibrated sensors. It measures heat transfer resistance to ensure compliance with ISO 12127-1 and EN/DIN standards, critical for certifying fire-resistant garments used in welding, foundries, and industrial safety. Delivers precise, reliable data for global PPE manufacturers and testing labs.

Standard

1. ISO 12127-1:2015

- Title: Clothing for protection against heat and flame — Determination of contact heat transmission through protective clothing or constituent materials — Part 1: Contact heat produced by heating cylinder

- Content: This standard specifies the method for measuring the thermal conductivity of protective clothing or its materials using a heating cylinder to simulate high temperature contact (100°C to 500°C). During the test, the calorimeter contacts the heating cylinder at a speed of 5mm/s, applies a force of 49N, and records the time required for the temperature to rise by 10°C.

- Current status: It replaces ISO 12127-1:2007 and is the current valid version.

2. EN ISO 12127-1:2015

- The version adopted by the European Committee for Standardization (CEN) is consistent with the content of ISO 12127-1:2015 and is applicable to the European Union.

3. DIN EN ISO 12127-1

- German standardized version, also based on ISO 12127-1:2015, used for testing and certification in Germany and German-speaking countries.

Other related standards

1. DIN EN 702

- Title: Protective clothing — Protection against heat and fire — Test method for determining the heat transmission on exposure to flame

- Application: Often used in conjunction with ISO 12127-1, especially in the German standard system, to evaluate the heat transmission performance of protective clothing under flame exposure.
