IEC 60695-11-4 Figure 1 Copper Block | 1.76g Copper Block

Durable Combustion Testing Equipment Copper Block IEC 60695-11-4 Figure 1

The IEC 60695-11-4 Figure 1 Copper Block is a high-precision calibration tool used to verify the thermal performance of 50 W test flames. During the calibration process, the copper block is exposed to the test flame, and the temperature rise is measured to confirm that the flame delivers the required energy level as specified in the standard.

Manufactured from high-conductivity electrolytic copper with strict weight and dimensional control, this block ensures consistent and repeatable calibration results. It is an essential accessory for laboratories performing flammability testing in accordance with IEC 60695-11-4.

Professional Construction & Technical Precision

This copper block is precisely machined from high-purity electrolytic copper to achieve a consistent mass of 1.76 g ± 0.01 g before drilling. The strict weight tolerance and dimensional accuracy ensure reliable thermal response during calibration, allowing laboratories to accurately assess the energy delivered by 50 W test flames.

The component is designed for repeated use in laboratory environments while maintaining stable physical and thermal characteristics when properly handled and stored.

Testing Principle

The calibration method specified in IEC 60695-11-4 Figure 1 uses a copper block to verify the thermal output of the 50 W test flame. The block is positioned at a defined distance from the flame, and the temperature rise over a specified period is measured.

This method provides an objective and repeatable means of confirming that the test flame meets the required energy characteristics, helping laboratories maintain test accuracy and consistency across different equipment.

Common Error Mitigation

To achieve reliable calibration results when using the copper block, the following practices are recommended:

• Ensure the copper block is clean and free from oxidation or residue before each use.
• Position the block accurately according to the distance specified in the calibration procedure.
• Use a properly calibrated temperature measurement system with appropriate response time.
• Allow the block to return to ambient temperature between calibration cycles.
• Regularly inspect the weight and surface condition of the copper block.
• Follow the exact temperature rise criteria defined in IEC 60695-11-4 Figure 1.
• Maintain clear documentation of calibration results for traceability.
