UL 1017:2023 Figure 9 Impactor 6.35mm

The UL 1017:2023 Figure 9 Impactor is a dedicated testing tool for evaluating the impact resistance of vacuum cleaners, blower cleaners, and household floor finishing machines. Crafted from solid steel for consistent weight and durability, it features a 6.35mm diameter, 17mm length, and total mass of 225g—with a 3.175mm rounded radius to mimic real-world accidental impacts (e.g., small objects falling onto equipment). It’s designed to test if equipment casings or components can withstand such impacts without exposing hazardous parts (like live wires or moving gears). Essential for manufacturers, it ensures compliance with UL safety standards, keeping household cleaning machines safe for daily use.

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 shape during impacts)
Key Dimensions:
– Diameter: 6.35mm ± 0.05mm
– Length: 17mm ± 0.1mm
– Rounded Tip Radius: 3.175mm ± 0.02mm (prevents excessive surface damage during testing)
– Total Mass: 225g ± 2g (critical for simulating standard impact force)
Impact Simulation: Mimics accidental small-object impacts (e.g., debris falling onto equipment) per UL/CSA/IEC safety criteria
Core Function: Tests if cleaning machine casings/components withstand impacts without exposing hazardous parts; validates structural integrity; ensures compliance with global safety standards

Test Procedures:
1. Inspect the impactor for dents, bending, or mass deviations; confirm mass is 225g ± 2g with a calibrated scale.
2. Place the machine under test (EUT, e.g., a vacuum cleaner) on a flat, stable surface—position it as in normal use.
3. Identify critical test points (e.g., EUT casing, control panel, air intake grilles) per safety standards.
4. Hold the impactor vertically above the test point; release it to allow free fall (or apply specified force) to strike the EUT.
5. After impact, check the EUT for cracks, loose parts, or exposed hazardous components.
6. Record results: Pass if no damage/hazard exposure; Fail if structural integrity is compromised.

Applications:
1. Testing vacuum cleaner body casings (per UL 1017:2023 Figure 9) to ensure impacts don’t expose internal live wires.
2. Verifying blower cleaner air outlet grilles (compliant with CSA C22.2 No.243:2023) to prevent impact-induced gear exposure.
3. Evaluating household floor polisher base durability (per IEC 60335-2-2:2021) to withstand accidental drops of small objects.
4. Quality control for vacuum cleaner manufacturers, validating casing impact resistance against UL 1017 requirements.
5. Post-production testing of wet/dry vacuum cleaner tank exteriors to meet global household cleaning equipment safety rules.
