WALL-MOUNTED PENDULUM HAMMER
1. BASE UNIT: WALL-MOUNTED PENDULUM APPARATUS (IK07-IK10)
This apparatus performs Test Eha: Pendulum Hammer according to IEC 60068-2-75, covering mechanical impact resistance from IK07 to IK10. It is the central mounting system for all striking elements.
Product Name: Wall-Mounted Pendulum Hammer Dart Launcher - IK07-IK10 Series
Base SKU: OTY068-BASE01
Standards Applied: IEC 60068-2-75 (Test Eha) and IEC 62262 (IK Rating).
Function: Used to determine the degree of protection (IK Code) of product enclosures against external mechanical impacts, specifically for medium to high energy levels (2 J to 50 J).
Mounting Requirement: The base unit must be fixed to a rigid support (e.g., a sturdy wall or separate floor stand) with a mass of 10 kg or More to ensure accurate test results (IEC 60068-2-75, Clause 4.2).
Key Dimensions: Features a nominal pendulum arm length of 1000 mm.
Mechanism: Includes a robust steel pendulum arm and a precise release mechanism (manual or electromagnetic) designed for minimal friction.
2. STRIKING ELEMENTS (HIGH ENERGY)
These are the interchangeable components that define the impact energy and, consequently, the IK rating achieved. Each element strictly conforms to Table 1 and Annex A of IEC 60068-2-75. All high-energy faces are made of Steel Fe 490-2 (Hardness HRE 80 to 85).

Specifications: This element delivers an impact energy of 10 J. It has an equivalent mass of 5 kg (+/- 2%), a striking face radius (R) of 50 mm, and a diameter (D) of 80 mm.
🔨 20 Joule Element (IK10)
Element SKU: OTY068-E20J
IK Rating: IK10
Specifications: This element delivers an impact energy of 20 J. It has an equivalent mass of 5 kg (+/- 2%), a striking face radius (R) of 50 mm, and a diameter (D) of 100 mm.
🔨 50 Joule Element (Maximum Energy)
Element SKU: OTY068-E50J
IK Rating: Exceeds standard IK10
Specifications: This is the highest energy element covered by the standard, delivering 50 J. It has an equivalent mass of 10 kg (+/- 2%), a striking face radius (R) of 50 mm, and a diameter (D) of 125 mm.
3. OPTIONAL STRIKING ELEMENTS AND ACCESSORIES
These items complement the base unit, allowing for lower-energy testing (often using Polyamide faces) or maintenance/setup functions.
🧲 Striking Element 0.5 J (IK04)
Element SKU: OTY068-E005J
Description: This element is used for lower-energy impact testing, corresponding to IK04. The striking face is made of Polyamide (Hardness HRR 85 to 100) to meet the material requirements for lower energy levels as specified by the standard.
🧲 Striking Element 1.0 J (IK06)
Element SKU: OTY068-E01J
Description: This element is used for lower-energy impact testing, corresponding to IK06. Like the 0.5 J variant, it features a Polyamide (Hardness HRR 85 to 100) striking face, essential for accurate results in this energy range.
🔬 Pendulum Calibrator
Accessory SKU: OTY068-CAL-P
Description: A precision accessory kit used to verify and calibrate the released impact energy of the pendulum system. Ensures the apparatus maintains +/- 2% accuracy on the equivalent mass and correct drop height, guaranteeing compliance with IEC 60068-2-75 requirements over time.
🧱 Rigid Floor Stand (Optional)
Accessory SKU: OTY068-SUP-RIG
Description: An optional heavy-duty, freestanding structure designed to provide the required 10 kg or More of rigid support mass when the base unit cannot be mounted directly onto a suitable wall. This ensures flexibility in laboratory setup.
