HAIDA HD-F736-2 Mattress Impact Testing Machine

Overview

The HAIDA HD-F736-2 Mattress Impact Testing Machine is a purpose-built mechanical durability tester engineered for standardized cyclic impact evaluation of domestic and commercial mattresses. It operates on the principle of controlled gravitational drop-weight impact—where a calibrated 25 kg hammer is elevated to a defined height and released under gravity to deliver repeatable kinetic energy to the mattress surface. This method simulates long-term dynamic loading conditions experienced during real-world use, enabling quantitative assessment of structural integrity, spring system resilience, foam layer fatigue resistance, and overall dimensional stability after repeated mechanical stress. Designed in strict alignment with EN 1725:1998 “Furniture — Beds and Mattresses — Test Methods for Durability,” the system provides objective, reproducible data essential for product development, quality assurance, and regulatory conformance in furniture manufacturing and third-party testing laboratories.

Key Features

• Robust steel frame construction with reinforced base plate and vertical guide columns ensures minimal deflection and high repeatability across thousands of impact cycles.
• Programmable impact frequency and drop height (within EN 1725-specified range) via intuitive 7-inch HMI touchscreen interface, integrated with INOVANCE PLC for deterministic motion control and cycle logging.
• Dual-mode operation: manual single-drop mode for diagnostic verification and automatic continuous cycling mode for endurance testing up to predefined cycle counts (e.g., 10,000–50,000 impacts).
• Pneumatically assisted hammer lifting and locking mechanism (6–8 bar supply) guarantees consistent release timing and eliminates operator-induced variability.
• Modular test bed design accommodates mattresses up to 2200 mm (L) × 2000 mm (W) × 400 mm (H), with adjustable support rails and non-slip surface to prevent lateral displacement during testing.
• Real-time status monitoring including cycle count, elapsed time, fault codes, and pneumatic pressure feedback—all traceable and exportable via USB or optional RS-485 interface.

Sample Compatibility & Compliance

The HD-F736-2 accepts full-size mattresses (twin, full, queen, king, and custom dimensions within envelope limits) without disassembly. Foam-core, innerspring, hybrid, and air-supported constructions are all compatible, provided specimens meet minimum density and thickness thresholds specified in EN 1725. The instrument satisfies Clause 6.3 (Impact Durability Test) of EN 1725:1998, including requirements for impact head geometry, mass tolerance (±0.5%), drop height accuracy (±2 mm), and impact location protocol (center and quarter-point positions). While not certified to ISO/IEC 17025 itself, the machine supports GLP-compliant testing workflows when used with documented SOPs, calibration records for the impact hammer (traceable to national standards), and periodic verification of drop height and release timing.

Software & Data Management

The embedded PLC-based control system logs each impact event with timestamp, cycle number, and operational status. Test reports—including total cycles, duration, anomalies, and pass/fail determination per EN 1725 criteria—are generated in PDF format and stored locally on the controller’s internal memory. Data export is supported via USB flash drive in CSV and PDF formats for integration into LIMS or QA documentation systems. Optional Ethernet connectivity enables remote monitoring and centralized test fleet management. All firmware updates and configuration backups adhere to version-controlled procedures compliant with internal audit requirements for equipment qualification (IQ/OQ).

Applications

• Endurance validation of mattress support systems prior to mass production launch.
• Comparative analysis of competing foam formulations or spring tempering processes under identical impact loads.
• Root-cause investigation of premature sagging or edge collapse in field-failure investigations.
• Supplier qualification testing for OEM mattress manufacturers requiring third-party verified durability metrics.
• Compliance verification for CE marking submissions where EN 1725 conformance is mandated.
• Research applications in ergonomics and sleep science labs evaluating biomechanical response to repetitive loading.

FAQ

What standards does the HD-F736-2 explicitly support?
EN 1725:1998, specifically Clause 6.3 for impact durability testing of mattresses.
Is the 25 kg impact hammer calibrated and traceable?
Yes—the standard hammer is supplied with a calibration certificate indicating mass deviation within ±0.5% against national metrological standards.
Can the drop height be adjusted beyond EN 1725 requirements?
Yes; while default settings comply with EN 1725 (typically 100 mm), the HMI allows user-defined heights between 50 mm and 200 mm for R&D or custom protocols.
Does the system support automated pass/fail evaluation?
It logs cycle data and flags mechanical faults (e.g., missed release, abnormal deceleration), but final pass/fail judgment requires post-test visual and dimensional inspection per EN 1725 acceptance criteria.
What maintenance intervals are recommended?
Monthly visual inspection of guide rails and pneumatic lines; annual verification of drop height accuracy and hammer mass; biannual lubrication of lifting mechanism per manufacturer’s technical bulletin.
