IEC61010-1 Clause 8.2.2 Figure 10 Steel Sphere Drop Impact Testing Machine for Medical Electrical Equipment
1. Introduction
The steel
sphere drop impact test equipment is designed and manufactured according to the requirements of
IEC61010-1 clause 8.2 and Figure 10, IEC60601-1 clause 15.3.3,
IEC60950-1 clause 4.4.5 and Figure 4A, IEC60598-1 clause 4.13.4,
IEC62368-1 Appendix clause T.6 and Figure T.1. Different steel
balls can be configured according to different standard
requirements. The equipment can provide both pendulum sphere impact
and vertical drop sphere impact. This tester uses the principle of
electromagnet attraction to attract various steel balls, and
releases or attracts the test steel balls through the magnetic
release or attraction generated by the on and off power of the
electromagnet to achieve drop ball impact. The pendulum ball is
raised by a steel rope, and the impact energy generated by the
height difference is quantified to provide the pendulum ball impact
energy required for the test. The default configuration of the drop
ball impact tester is Φ50mm steel ball, and the Φ50.8mm steel ball
required by the UL standard is optional. Because stainless steel
balls are non-magnetic, the configured steel balls are bearing
steel balls. Please pay attention to grease them for maintenance to
avoid rust.

3. Application
The steel ball
drop test device is mainly used to simulate the free-fall impact of objects at a
certain height, so as to evaluate the performance of related
materials, products or structures. Its specific uses are as
follows:
3.1 Material Performance Testing
- Evaluate Material Toughness: By allowing the steel ball to drop onto the surface of the tested
material from different heights, observe the deformation, cracking,
and other conditions of the material under impact, and thus judge
the toughness of the material. For example, in the research and
development of metal materials, the impact resistance of metals
with different compositions or heat treatment processes can be
compared, providing a basis for the optimization of materials.
- Study Material Fatigue Characteristics: Conduct multiple steel ball drop impact tests to simulate the
impact loads that materials may bear during long-term use, analyze
the accumulation of fatigue damage in materials, and predict the
service life of materials in practical applications.
3.2 Product Quality Inspection
- Evaluation of Packaging Protection Performance: Place the packaged product under the test device and let the
steel ball drop onto the packaging to simulate the impacts that the
product may receive during transportation and handling. Check
whether the packaging materials and structure can effectively
protect the product, so as to optimize the packaging design and
reduce the damage of products during the logistics process.
- Drop Resistance Testing of Electronic Products: For electronic products such as mobile phones and tablets, fix
them on the test bench and conduct drop impact tests with steel
balls to evaluate the tolerance of the product's casing, screen,
internal components, etc. when subjected to accidental drop
impacts. This helps to improve the product's structural design and
enhance the reliability and durability of the product.
- Strength Inspection of Glass Products: For glass products such as glass containers and vehicle window
glass, the steel ball drop test can detect their impact resistance,
determine whether the products meet the quality standards and
safety requirements, and ensure the safety of the products during
normal use and possible accidental impacts.
3.3 Applications in the Construction and Engineering Field
- Impact Resistance Testing of Roof Tiles: Drop the steel ball onto the roof tiles to simulate natural
impact factors such as hailstones, evaluate the impact resistance
of the roof tiles, and provide a reference for the selection of
roof tiles and quality control, ensuring the waterproofing and
structural safety of buildings under adverse weather conditions
- Research on the Impact Resistance of Concrete: Through the steel ball drop test, study the mechanical response
of concrete under impact loads, and provide data support for the
application of concrete structures in engineering scenarios where
they are subjected to impact, such as military protection projects
and blast-resistant structures.
3.4 In the Field of Scientific Research and Teaching
- Provide Data Support for Academic Research: In the research of disciplines such as materials science and
mechanics, the steel ball drop test device can be used to obtain
dynamic response data of materials under impact loads, such as
stress, strain, and deformation patterns, providing experimental
basis for the establishment and verification of material
constitutive relations, impact dynamics theoretical models, etc.
- Serve as a Teaching Demonstration Tool: During the teaching process of relevant majors, use the steel
ball drop test device for on-site demonstrations, allowing students
to intuitively observe the impact phenomenon, understand relevant
knowledge such as material mechanical properties and impact
dynamics, and improve students' interest in learning and their
ability to understand theoretical knowledge.
