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.
