Product Introduction
IEC60335-1 Clause 21 Hardened Scratching Steel Pin Probe
Type：BND-HHZ-40
Product Features:
1. The end of the steel pin is designed in the form of a cone with a 40° angle, fully compliant with IEC60335-1 21.2.
2. ISO 17025 / ILAC calibration certificate available (additional cost).
Detailed Description:
The IEC60335-1 Clause 21 Hardened Scratching Steel Pin Probe is an essential tool for testing the strength of solid insulation against penetration by sharp implements. This probe is meticulously designed to meet the stringent requirements set forth in the IEC60335-1 standard, ensuring accurate and reliable test results.
Key Specifications:
*Cone Angle: The end of the steel pin is conically shaped at a precise angle of 40°, ensuring compliance with IEC60335-1 21.2.
*Tip Radius: The tip is rounded with a radius of 0.25 mm ± 0.02 mm, providing consistent performance during tests.
*Testing Angle: The pin is held at an angle of 80°–85° to the horizontal during testing.
*Force Applied: A force of 10 N ± 0.5 N is exerted along its axis during scratching tests.
*Scratching Speed: The pin moves along the surface at approximately 20 mm/s, creating two parallel scratches spaced sufficiently apart.
*Perpendicular Force Test: A force of 30 N ± 0.5 N is applied perpendicularly to an unscratched part of the surface for further testing.
Compliance Testing
The purpose of this probe is to ensure that accessible parts of solid insulation have sufficient strength to prevent penetration by sharp implements. Compliance is verified through a series of tests involving temperature elevation, scratching, and electric strength assessment.
Test Procedures:
1. Raise the insulation to the temperature measured during Clause 11 tests.
2. Scratch the insulation surface using the hardened steel pin as described above.
3. Apply the test fingernail with a force of approximately 10 N to check for further damage.
4. Conduct an electric strength test with the pin applied perpendicularly.
Calibration Services
We offer ISO 17025 / ILAC calibration certificates for our probes, ensuring they meet international standards for accuracy and reliability. Please note that this service incurs an additional cost.
