UL 1017:2023 Figure 9 Impactor 6.35mm

The UL 1017:2023 Figure 9 Impactor is a precision testing instrument engineered for evaluating the impact resistance of vacuum cleaners, blower cleaners, and household floor finishing machines in accordance with UL 1017:2023 safety standards. Fabricated from solid steel to ensure consistent mass distribution and structural integrity, this impactor features a 6.35mm diameter, 17mm length, and total mass of 225g—with a precisely machined 3.175mm rounded radius tip designed to simulate real-world accidental impacts from small falling objects.

This testing tool is essential for manufacturers and testing laboratories to verify that equipment casings and components can withstand specified impact forces without exposing hazardous parts such as live electrical conductors or moving mechanical components. Compliance with UL 1017:2023 ensures that household cleaning machines meet rigorous safety requirements for consumer protection.

Technical Specifications

• Tool Type: Impact Testing Tool (UL 1017:2023 Figure 9; for evaluating impact resistance of household cleaning/floor finishing machines)
• Material: Solid steel (high density for consistent mass; corrosion-resistant via natural steel properties; rigid to maintain dimensional stability during impact testing)
• Key Dimensions:
  • Diameter: 6.35mm ± 0.05mm
  • Length: 17mm ± 0.1mm
  • Rounded Tip Radius: 3.175mm ± 0.02mm (engineered to prevent excessive surface damage during testing)
  • Total Mass: 225g ± 2g (critical parameter for simulating standardized impact force)
• Impact Simulation: Replicates accidental small-object impacts (e.g., debris falling onto equipment) per UL/CSA/IEC safety criteria
• Core Function: Tests structural integrity of cleaning machine casings/components; validates compliance with UL 1017:2023 and related international safety standards
• Test Procedures:
  1. Inspect the impactor for dimensional deviations, surface defects, or mass variations; verify mass is 225g ± 2g using calibrated laboratory scales.
  2. Position the equipment under test (EUT, e.g., vacuum cleaner) on a level, stable surface in normal operating configuration.
  3. Identify critical test points (e.g., EUT casing, control interfaces, ventilation apertures) as specified in applicable safety standards.
  4. Orient the impactor vertically above designated test points; release to achieve free-fall impact conditions (or… (truncated)
