ISO 20567-1 Gravel Impact Tester for Automotive Coatings and EV Battery Pack Testing

Product information:

The Gravel Impact Resistance Testing Machine, also known as an automotive gravelometer or stone chip resistance tester, is designed to evaluate the durability of automotive coatings, painted surfaces, plated components, and battery pack enclosures against gravel and stone chip impacts. This test machine conforms to standards of ISO 20567-1.

By delivering controlled steel grit onto the specimen under adjustable air pressure and flow conditions, this testing system simulates gravel impact encountered during vehicle operation. It helps assess coating adhesion, surface damage, and the impact resistance of automotive materials under standardized laboratory conditions.

Key Features

• ISO 20567-1 Compliance: Designed for gravel impact resistance testing according to ISO 20567-1.

• Automatic Steel Grit Feeding: Adjustable feeding speed enables controlled delivery of impact media.

• Adjustable Test Parameters: Test pressure, operating time, and other variables can be configured through the control system.

• Touchscreen Operation: Supports fixed-value and programmable test procedures.

• Integrated Data Acquisition: Collects and exports test data with a minimum sampling time of ≤1 ms.

• Software Calibration: Provides calibration functions for physical quantities such as pressure and time.

• Impact Media Recovery: A dedicated collection system facilitates the recovery of steel grit after testing.

• 54° Specimen Mounting: Includes a VDA 54° impact head and corresponding specimen mounting arrangement.

• Enhanced Safety Construction: Steel test area and multiple protective functions support demanding automotive and battery testing environments.

• Movable Design: Facilitates equipment relocation and laboratory layout adjustments.

Applications

This ISO 20567-1 gravel impact tester is suitable for evaluating the resistance of automotive materials and protective surface coatings to stone chip damage.

Typical applications include:

1. Automotive Paint and Coating Testing

Evaluates the resistance of automotive paint films, protective coatings, and coated metal panels to gravel impact, helping manufacturers assess coating durability and surface damage.

2. Automotive Component Testing

Used to examine the resistance of vehicle body panels, metal components, and other coated automotive parts to impact from road debris.

3. EV Battery Pack Enclosure Testing

Suitable for gravel impact resistance evaluation of electric vehicle battery pack housings and protective enclosures.

4. Surface Treatment Performance Evaluation

Supports comparative testing of painted, plated, and other surface-treated specimens to assess their resistance to mechanical impact.

5. Automotive Material Research and Quality Control

Provides a laboratory testing solution for automotive manufacturers, coating suppliers, material research centers, and third-party testing laboratories.

Technical parameters:

Equipment configuration list:

Working conditions (equipment use environment):

1. Ambient temperature: 0~40℃

2. Ambient humidity: 25%~95%RH

3. Atmospheric pressure: 90~105kPa

4. Power supply: AC 380 V, 50 Hz, 2 kW

Safety protection:

1. The test area is composed entirely of high-temperature resistant and flame-retardant components (no plastic pipes, wires, rubber gaskets, seals, lubricants, engine oil, etc.), which can prevent damage to the equipment due to battery combustion and explosion.

2. The test area needs to have a high-strength, waterproof, rust-proof and corrosion-resistant design to avoid the adverse consequences of using water to extinguish fires during battery test combustion and explosion.

3. The equipment has an emergency stop switch, which can stop all tests in an emergency and cut off the power supply at the same time to avoid short-circuit hazards.

4. Limit protection device: The equipment is equipped with upper and lower limit protection devices.

5. The system is equipped with a protection module. When the pressure and time exceed the set value, the system automatically triggers the test stop and alarms.

6. The equipment has electrical safety that meets national standards and can effectively prevent and eliminate possible electric hazards to operators and maintenance personnel. During normal operation, except for the circuit part of the equipment, the outer shell of the equipment, the metal parts in the test box, etc. will not be charged. When an accident occurs to the equipment, such as fire, leakage, short circuit, etc., the equipment can automatically cut off the external input power so that no part of the equipment is energized.

7. The entire test area is installed with no electrical components, which are made of pure steel. Even if the battery burns during the test, it will not cause damage to the equipment.

8. Three-color indicator light: A three-color indicator light is installed on the top of the equipment to indicate the operating status of the equipment. It has an audible and visual alarm function, which can be manually eliminated after the fault response.
