IEC 60068-2-75 IK Code High Energy Pendulum Impact Test Apparatus Plug And Socket Test

Equipment information:

The high energy pendulum impact test apparatus is designed and manufactured according to the requirements of IEC60068-2-75, IEC60884-1:2013, IEC62262:2002 clause 6, etc.

It is used for the impact resistance test of household and similar electronic and electrical products and their accessories such as plugs and sockets and wall mounted mounting boxes, screw glands, covers, switches, lamps, etc., to assess the safety performance and strength level of the products.

Test Eha: Pendulum Hammer, the striking element is free released at a certain height through a 1 m pendulum tube, impact the specimen at the lowest point in the vertical direction, after the conversion of gravitational potential energy to kinetic energy, to achieve the purpose of impact test on the sample.

Features:

The High Energy Pendulum Impact Test Apparatus is a specialized testing device used to evaluate the impact resistance and toughness of materials, components, or structures. This apparatus is commonly employed in industries such as automotive, aerospace, construction, and manufacturing, where impact resistance is critical for ensuring product safety and reliability.

The main components and features of a typical High Energy Pendulum Impact Test Apparatus include:

Pendulum: The apparatus consists of a heavy pendulum arm, usually made of steel or other durable materials. The pendulum is designed to store a significant amount of potential energy when raised to a certain height.
Release Mechanism: A release mechanism is incorporated to enable controlled and precise release of the pendulum. This mechanism ensures consistent and repeatable impacts during testing.
Specimen Holder: The apparatus includes a specimen holder or fixture where the test sample is securely mounted. The specimen holder is designed to accommodate different sample sizes and shapes, ensuring proper alignment and stability during impact.
Energy Measurement System: The apparatus is equipped with an energy measurement system, typically including sensors or load cells, to accurately measure the impact energy delivered to the test specimen. This enables precise quantification of the impact resistance and toughness of the tested material or component.

The High Energy Pendulum Impact Test Apparatus allows for controlled and repeatable impact testing, simulating real-world scenarios in which materials or components may be subjected to sudden impacts or collisions. It helps assess the ability of a material to absorb energy and resist fracture or deformation under impact loading.

It is important to follow relevant testing standards or specifications, such as ASTM, ISO, or industry-specific guidelines, when conducting impact tests using the High Energy Pendulum Impact Test Apparatus. These standards provide specific procedures, parameters, and acceptance criteria for impact testing based on the intended application or industry requirements.
