Product catalog summary
Overview: The document provides a detailed technical description of the MULTI GRIT TESTER 508 VDA and 508 SAE, which are stone hammer blow testing instruments used to assess the durability of paint and coating materials against impacts. These instruments are designed to meet various national and international standards.
Specifications:
  • 508 VDA: Dimensions: 1750 x 500 x 1220 mm, Weight: approx. 100 kg, Compressed air connection: 6-10 bar, Power supply: 85-264 VAC.
  • 508 SAE: Dimensions: 1600 x 500 x 1250 mm, Weight: approx. 100 kg, Compressed air connection: 8-10 bar, Power supply: 85-264 VAC.
Testing Standards:
  • 508 VDA complies with DIN EN ISO 20567-1, FORD FLTM BI 157-06, RENAULT D24 1702, PSA D24 1312, DAIMLER DBL 5416.
  • 508 SAE complies with SAE J 400, ASTM D 3170.
Principle of the Test: Both models use impact bodies to simulate the effects of small, high-speed impacts on coatings. The VDA model uses a fixed 54° impact angle, while the SAE model allows adjustable angles from 30° to 90°.
Design and Operation: The instruments feature high precision and repeatability. They use compressed air to accelerate steel shot or grit towards the specimen. The VDA model includes a touch panel for control, while the SAE model features an LCD display.
Accessories: Optional attachments are available for specific testing standards and configurations, such as vertical impact angles and testing on three-dimensional objects.
Order Information: The document lists order numbers for different configurations and accessories, including attachments for specific standards and impact cabinets.
Additional Notes: The document mentions the GRITSCAN analysis system for capturing and analyzing impact images, and notes that technical modifications may occur.

VDA Stone Hammer Blow Test Instrument, MULTI GRIT TESTER 508 VDA Accessories (option) The MULTI GRIT TESTER 508 VDA is a stone hammer blow testing instrument that at first was developed in co-operation with the "Verband der Automobilindustrie (VDA)" (Association of the Automotive Industry) but now also meets the specifications of national and international standards. The MULTI GRIT TESTER 508 VDA is used to assess the ability of single and multiple layers of paints and similar coating materials to stand up to the impacts caused by small bodies of low mass hitting the specimen at high speed as...

SAE Stone Hammer Blow Test Instrument, MULTI GRIT TESTER 508 SAE Purpose and Application The new MULTI GRIT TESTER 508 SAE is a stone hammer blow testing instrument equipped with an adjustable impact angle, contrary to the execution of VDA. Contrary to the VDA version, the test panel in the MULTI GRIT TESTER 508 SAE is located completely within the testing room during the whole bombardment procedure. Due to numerous technical differences between both versions (conditional on the standards), a test in accordance with VDA using the SAE version, is not intended and thus technically excluded. A defined...
