Tubular Impact Tester
Model No. :
Brand : BEVS
The BEVS Tubular Impact Tester is a precision instrument designed for objective and qualitative evaluation of coating resilience by simulating real-world mechanical impact conditions. It determines the degree of damage, such as cracking or peeling, caused by a free-falling weight rapidly deforming the coated surface and its substrate.
- Simulates real-world impact stress accurately.
- Reliably measures coating craze or damage.
- Versatile for various protective materials.

Features
- Robust Construction: The tester is built with a sturdy base plate and a solid tubular frame, ensuring stability and perpendicular alignment for precise, repeatable drop tests.
- Variable Drop Energy: Features a graduated vertical tube, typically marked up to cm or inches, allowing the operator to select and set a precise drop height to vary the impact energy.
- Clamp Ring Mechanism: Includes an adjustable clamp ring to securely hold the falling weight at the user-defined height, guaranteeing the impact occurs from the exact, required distance.
- Adaptable Configuration: Accommodates multiple testing configurations through a selection of different falling weights, indenter diameters (e.g., ), and die apertures to comply with diverse international standards.
- Manual Precision Operation: The simple, mechanical design allows for highly controlled and user-initiated release of the falling mass, which is guided through the tube for a perfectly centered impact on the test panel.

FAQs
Which specific international standard does the BEVS 1601/1 comply with?
This model is manufactured specifically to meet the technical requirements of the ASTM D2794 standard, which covers the testing of organic coatings’ resistance to rapid deformation.
What is the falling weight mass used in the 1601/1 model?
The standard falling mass for this model is 8.9 N, which converts to 2 Lbs (Pounds), making it suitable for lower-force impact testing scenarios defined by its compliance standard.
What are the key diameters of the indenter and die for this model?
The technical specifications include a 15.9 mm indenter diameter and a 16.3 mm die diameter. These dimensions are critical for maintaining the test’s precision and adherence to the standard’s geometry.
Is the instrument suitable for both direct and reverse impact testing?
Yes, like other models in the series designed for ASTM D2794, the 1601/1 can be used for both direct impact (striking the coated surface) and reverse impact (striking the substrate side) to fully assess coating performance.
What types of materials are typically tested with this instrument?
It is used in quality control and R&D to test the adhesion and flexibility of paint, lacquer, and other organic coatings applied to metal, plastic, or composite test panels.
