Product Features

1. The end of steel pin, having the form of a cone with an angle of 40°, fully in accordance with IEC60335-1 21.2.

2. ISO 17025 / ILAC calibration certificate available. (with extra cost)

Product Introduction 

21.2 Accessible parts of solid insulation shall have sufficient strength to prevent penetration by sharp implements.

Compliance is checked by subjecting the insulation to the following test, unless the thickness of supplementary insulation is at least 1 mm and that of reinforced insulation is at least 2 mm.

The insulation is raised to the temperature measured during the test of Clause 11. The surface of the insulation is then scratched by means of a hardened steel pin, the end of which has the form of a cone with an angle of 40°. Its tip is rounded with a radius of 0,25 mm ± 0,02 mm. The pin is held at an angle of 80°– 85° to the horizontal and loaded so that the force exerted along its axis is 10 N ± 0,5 N. The scratches are made by drawing the pin along the surface of the insulation at a speed of approximately 20 mm/s. Two parallel scratches are made. They are spaced sufficiently apart so that they are not affected by each other, their length covering approximately 25 % of the length of the insulation. Two similar scratches are made at 90° to the first pair without crossing them.

The test fingernail of Figure 7 is then applied to the scratched surface with a force of approximately 10 N. No further damage, such as separation of the material, shall occur. The insulation shall then withstand the electric strength test of 16.3.

The hardened steel pin is then applied perpendicularly with a force of 30 N ± 0,5 N to an unscratched part of the surface. The insulation shall then withstand the electric strength test of 16.3 with the pin still applied and used as one of the electrodes.

Calibration Certificate

*Here are some tips to keep in mind for calibration

1.Accreditation: Ensure that the calibration certificate is issued by a laboratory accredited according to ISO 17025. This standard ensures the laboratory's competence in performing calibration and testing.

2.Cost and Time: Be aware that calibration incurs an extra cost and typically requires 7 to 10 workdays to complete. Plan ahead to accommodate this timeframe in your schedule.

3.Recalibration Interval: Follow the suggested recalibration interval of one year. Regular recalibration helps maintain the accuracy and reliability of your equipment.

4.Certification Details: Each calibration certificate covers only one item. Make sure the certificate includes your company's name and address, as this will be indicated on the cover. This detail ensures that the certificate is properly attributed to your equipment
