FBT-01 Drop Ball Impact Tester

The main variables in the test include:

• Drop Height: Adjustable between 300mm to 600mm (extendable based on requirements).
• Ball Size and Mass: Available in sizes like 23mm, 25mm, 28.6mm, and more.
• Impact Energy: The impact energy generated by the ball hitting the sample is analyzed to evaluate the material’s performance under shock loads.

The Importance of the Ball Dropping Test in Material Testing

The ball dropping test, a standard procedure in impact resistance evaluation, measures how materials respond to the sudden force of a falling steel ball. This test is particularly essential for safety applications, such as protective eyewear, to comply with ANSI Z87.1 standards.

How the Ball Dropping Test Works

• A steel ball of known weight and diameter is released from a predefined height.
• The ball impacts the test specimen, simulating real-world impact conditions.
• Observations are made on deformation, cracking, or penetration to assess the material’s impact resistance.
• Test results help determine whether the material meets industry safety and durability standards.

ANSI Z87.1 Compliance: Key Testing Standards for Eye Protection

ANSI Z87.1 specifies rigorous impact resistance requirements for protective eyewear. One of the primary methods to assess compliance is the 9.6 Drop Ball Test, which includes:

• Apparatus: A rigidly mounted headform with a 30 kg base, ensuring stability.
• Test Procedure: A 25.4 mm (1.0 in.) diameter steel ball, weighing 68 g (2.4 oz.), is dropped from 127 cm (50 in.) onto the lens.
• Assessment Criteria: If the eyewear withstands the impact without fracture or penetration, it passes the test.

Factors Influencing Impact Test Results

Several variables affect the outcome of a ball impact test, including:

1. Drop Height: The greater the height, the stronger the impact force.
2. Ball Mass and Diameter: Heavier and larger balls exert higher impact forces.
3. Material Properties: Hardness, flexibility, and composition influence impact resistance.
4. Clamping Method: Securely clamping the specimen ensures accurate results.

Applications of the Drop Ball Impact Tester

The Drop Ball Impact Tester is widely used across industries to ensure material quality and durability:

• Packaging: Testing film and plastic sheets for packaging to ensure they can withstand rough handling during transport.
