Figure 6-1. Traceability

*The Guarded Hot Plate Method (GHP Method) is a thermal conductivity measurement method of insulation

material by the absolute method based on JIS A 1412. By measuring the power applied to the main heat plate,

calculate the heat flow which flows through the sample piece and determine the heat flow rate from the

temperature difference and thickness of the sample.

By keeping the protecting plate around the main heat plate at same temperature as the main heat plate, the

heat flow runs through the sample achieves the primary flow (the heat flows in perpendicular to the sample).

6-3. Troubleshooting

Check the following items in case of trouble with the instrument. If any questions should remain, contact EKO

for further technical support.

JIS A 1412

Check the resistance.

Check the connection of the lead wires.

Check the sensor contacting and adhesion conditions.

Calibrate EKO Reference Plate with the device

which complies with GHP method.

Using calibrated EKO Reference Plate, calibrate the

reference heat flow sensor periodically.

Calibrate the production heat flow sensor according to

the HFM method complying with JIS A 1412.
