High Energy Pendulum Hammer Impact Test Apparatus SN2122A – IEC 62262 IK07–IK10 Impact Resistance Testing

The High Energy Pendulum Hammer Impact Test Apparatus SN2122A is designed to evaluate the mechanical strength and impact resistance of electrical and electronic products, enclosures, and their accessories against external mechanical impacts.

It is suitable for testing household and similar electrical appliances, plugs and socket-outlets, wall-mounted mounting boxes, screw glands, covers, switches, luminaires, and other electrical components. By applying controlled impact energy to specified positions on a test specimen, the apparatus helps manufacturers and testing laboratories assess product durability, enclosure strength, and protection against mechanical impacts.

The SN2122A supports four standard impact energy levels: 2 J, 5 J, 10 J, and 20 J, corresponding to IK07, IK08, IK09, and IK10 respectively. It is suitable for mechanical impact testing in accordance with IEC 62262, IEC 60068-2-75, IEC 60598-1, and EN IEC 61851-1.

With its movable trolley structure, electrically adjustable impact point, adjustable impact angle, and electromagnetic release mechanism, the SN2122A provides a flexible solution for high-energy pendulum impact testing.

The SN2122A is particularly suitable for manufacturers and laboratories that need to verify the mechanical strength of electrical equipment and protective enclosures.

Typical applications include:

• Electrical Enclosures: Evaluating the resistance of electrical equipment enclosures against external mechanical impacts according to IEC 62262.

• Plugs and Socket-Outlets: Assessing the mechanical strength of plugs, socket accessories, and mounting boxes.

• Lighting Equipment: Testing luminaires and their enclosures in accordance with IEC 60598-1.

• Electric Vehicle Charging Equipment: Performing mechanical impact tests on EV charging equipment in accordance with EN IEC 61851-1 and IEC 61851-1.

• Household Electrical Appliances: Evaluating the impact resistance of switches, covers, screw glands, and other electrical accessories.

• Quality Control Laboratories: Supporting product development, mechanical strength verification, and routine quality inspection.

The SN2122A adopts a trolley-type structure with casters, allowing the apparatus to move easily around the test specimen and align with different impact positions.

Its key structural features include:

1. Adjustable Impact Position

The impact point can be electrically adjusted up and down through a screw guide, with an adjustment stroke of 200–1200 mm. This allows operators to position the striking element at different heights according to the specimen's testing requirements.

2. Adjustable Impact Angle

The impact angle can be adjusted from 0° to 90°, providing flexibility when testing different surfaces and impact directions.

3. Pendulum Impact Structure

The apparatus uses a 1000 mm steel pendulum tube. The striking element is released from a specified height and swings freely under gravity, impacting the specimen at the lowest point of its trajectory.

During this process, gravitational potential energy is converted into kinetic energy, delivering the required impact energy to the test specimen.

4. Electrical Lifting and Electromagnetic Release

The apparatus features electrical lifting and an electromagnetic release mechanism, making the operation more convenient and helping achieve consistent impact release.

5. Stable Supporting Structure

A thickened, load-bearing steel base plate provides stable support during testing. The movable trolley allows the apparatus to be repositioned according to the location of the specimen's impact point.

6. Anti-Secondary Impact Function

The built-in anti-secondary impact function helps prevent the striking element from delivering an unintended second impact after the initial strike, supporting controlled impact testing.

The SN2122A provides four standard impact energy levels for evaluating the mechanical protection of electrical enclosures.

According to IEC 62262, the corresponding IK classifications are:

These impact energy levels allow manufacturers and testing laboratories to evaluate enclosure resistance under different mechanical impact conditions.

For applications requiring higher impact energy, 50 J is identified as a recommended value in the relevant standard information. The standard configuration of SN2122A specified here covers up to 20 J.

The High Energy Pendulum Hammer Impact Test Apparatus SN2122A is designed for testing applications associated with the following standards:

• IEC 60068-2-75:2014 – Environmental testing for electric and electronic products – Part 2: Test methods – Test Eh: Hammer tests.

• IEC 60598-1:2017 – Luminaires – Part 1: General requirements and tests.

• IEC 62262:2002 – Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK Code).

• EN IEC 61851-1:2019, Clause 12.11 – Electric vehicle conductive charging system – Part 1: General requirements.

• IEC 61851-1:2017, Clause 12.11 – Electric vehicle conductive charging system – Part 1: General requirements.

The SN2122A combines high-energy impact capability with a flexible mechanical structure to support different testing requirements.

• Multiple Impact Energy Levels: Four standard energy levels from 2 J to 20 J, covering IK07–IK10 impact testing.

• Flexible Positioning: Electrically adjustable impact height and 0–90° impact angle.

• Convenient Operation: Electrical lifting and electromagnetic release simplify test operation.

• Stable Construction: A reinforced steel base plate supports stable positioning during impact testing.

• Easy Mobility: The trolley structure with casters allows convenient movement around the specimen.

• Controlled Impact: An anti-secondary impact function helps prevent unintended repeated impacts.

The SN2122A provides a practical testing solution for electrical product manufacturers, third-party testing laboratories, certification organizations, and quality control departments that require reliable mechanical impact resistance evaluation.
