Overview
The YinZong Ball Impact Tester YT-330 is a precision-engineered mechanical impact testing system designed to evaluate the ballistic resistance and structural integrity of protective eyewear and face shields under standardized projectile impact conditions. It operates on the principle of gravity-assisted free-fall impact, where test projectiles—representing sport-specific balls—are released from a calibrated height onto the specimen mounted on a CSA-certified adult male headform. The system strictly adheres to ASTM F803–22 “Standard Specification for Eye Protectors for Paintball Sports” and incorporates design elements compatible with broader ophthalmic impact assessment protocols used in occupational safety (e.g., ANSI Z87.1), military eyewear qualification (MIL-PRF-32432), and international sports equipment certification frameworks.
Key Features
- Robust steel frame construction with vibration-dampening base, ensuring high repeatability and measurement stability across repeated impact cycles.
- Adjustable drop-height mechanism calibrated to deliver consistent kinetic energy per test—configurable to meet ASTM F803’s specified impact velocities for each ball type.
- Integrated CSA-compliant adult male headform (heart-shaped mounting base included) with standardized anatomical curvature and material rigidity for realistic load distribution during impact.
- Modular test tube assembly system: pre-installed tubes for squash ball (Ø 40.0 ± 0.5 mm, mass 24.0 ± 1.0 g) and tennis ball (Ø 65.1 ± 1.6 mm, mass 57.6 ± 0.9 g); additional tube sets available for optional purchase (e.g., racquetball, field hockey ball, baseball).
- Compliance-ready design: facilitates traceable test execution, manual log recording, and integration into GLP/GMP-aligned quality control workflows for PPE manufacturers and third-party testing laboratories.
Sample Compatibility & Compliance
The YT-330 supports evaluation of rigid and flexible eyewear designs—including polycarbonate lenses, wraparound frames, and goggle-style assemblies—when mounted on the supplied CSA headform. It accommodates standard projectiles defined in ASTM F803, including but not limited to: racquetball (Ø 56.0 ± 0.5 mm, 40.0 ± 1.0 g), squash ball, tennis ball, women’s field hockey ball (141–148 g), and baseball (142–149 g). Cross-standard equivalency is supported per ASTM guidance: passing the squash ball test satisfies requirements for badminton, handball, and basketball eye protection; racquetball impact compliance extends to table tennis; and women’s field hockey ball impact qualifies eyewear for grass hockey applications. Note: users must supply an industrial-grade air compressor (≥5 kg/cm² output pressure) and a stable, level workbench (not included).
Software & Data Management
The YT-330 is a hardware-only, manually operated impact tester with no embedded digital controller or software interface. All test parameters—including ball type, drop height, specimen identification, pass/fail outcome, and visual inspection notes—are recorded via paper-based or laboratory information management system (LIMS)-integrated manual entry. This architecture ensures full auditability and avoids electronic validation overhead, aligning with ISO/IEC 17025:2017 Clause 7.7 (control of records) and FDA 21 CFR Part 11 requirements for non-automated instrumentation in regulated environments. Optional digital documentation kits (e.g., barcode-labeled test logs, PDF report templates) are available upon request to support CAPA tracking and internal quality audits.
Applications
- Pre-market validation of ANSI Z87.1-compliant safety eyewear for industrial, construction, and laboratory use.
- Design verification of sports eyewear intended for paintball, racquet sports, field hockey, and baseball.
- Conformance testing for military and law enforcement optical PPE under MIL-PRF-32432 Annex A (ballistic impact).
- Root cause analysis of lens fracture patterns and frame deformation mechanisms following impact failure.
- Supplier qualification and incoming inspection for eyewear component manufacturers (lens blanks, frame polymers, retention systems).
FAQ
Does the YT-330 include an air compressor?
No. Users must provide an external air compressor capable of delivering ≥5 kg/cm² (≈71 psi) pressure for pneumatic release actuation.
Can the tester be used for non-standard ball types?
Yes—provided custom test tubes are fabricated to ASTM F803 dimensional and mass tolerances and validated for consistent release dynamics.
Is calibration certification included with shipment?
The unit ships with a factory verification report confirming dimensional accuracy, headform geometry, and mechanical release consistency. Third-party ISO/IEC 17025 calibration services are available separately.
What maintenance is required?
Routine inspection of guide rails, release mechanism wear, and headform surface integrity is recommended every 200 test cycles; lubrication of moving parts per manufacturer guidelines.
Is the CSA headform compliant with EN 166 or ISO 12885?
The headform meets CSA Z94.3–19 specifications and is widely accepted for ASTM F803 testing; however, EN 166 requires EN 168-defined headforms, which are not supplied with this system.
