Overview
The HAIDA HD-D020 Hydrostatic Pressure Tester is a precision-engineered instrument designed for quantitative evaluation of the water resistance performance of flexible sheet materials—particularly woven and nonwoven textiles used in medical, industrial, and outdoor protective applications. It operates on the principle of static hydrostatic pressure measurement, applying controlled, incremental water column pressure to the specimen’s surface while monitoring the onset and progression of water penetration. This method conforms to internationally recognized physical test paradigms for barrier integrity assessment, where pressure is expressed in millimeters of water column (mm H₂O) or kilopascals (kPa), and breakthrough is objectively defined by the appearance of three discrete water droplets on the fabric’s reverse side under standardized observation conditions. The HD-D020 delivers repeatable, operator-independent results essential for quality control laboratories, R&D departments, and regulatory compliance verification workflows.
Key Features
- Digitally controlled hydraulic pressure generation system with real-time pressure ramping and hold functionality
- High-resolution pressure transducer calibrated to ±0.5% full scale, enabling accurate determination of hydrostatic head values up to 10,000 mm H₂O (98 kPa)
- Integrated specimen clamping mechanism ensuring uniform sealing and consistent test area exposure (100 cm² standard test area per ISO 811 and ASTM D751)
- Automated endpoint detection logic aligned with GB/T 4744–2013 and AATCC 127 criteria—triggered upon visual confirmation of three distinct water beads
- Stainless steel test chamber and fluid path components resistant to corrosion and compatible with deionized water or standardized test fluids
- Front-panel LCD interface with intuitive navigation, data logging capability, and USB export for raw pressure–time profiles
Sample Compatibility & Compliance
The HD-D020 accommodates flat, flexible specimens up to 300 mm × 300 mm in dimension and thicknesses ranging from 0.1 mm to 5 mm—including tightly woven cotton, polyester-cotton blends, laminated polyurethane-coated fabrics, microporous membranes, and SMS (spunbond-meltblown-spunbond) nonwovens. Its mechanical design and procedural logic are fully aligned with statutory and consensus-based standards governing barrier textile performance: GB 19082–2009 (Section 5.4.1) for disposable medical gowns; GB/T 4744–1997 and its updated revision GB/T 4744–2013; AATCC Test Method 127; ISO 811; and ASTM D751 (for coated fabrics). All test sequences support GLP-compliant documentation when paired with optional audit-trail-enabled software modules.
Software & Data Management
While the base HD-D020 operates via embedded firmware, optional PC-based software (HAIDA TestSuite v3.x) enables advanced data management capabilities including multi-sample batch reporting, statistical process control (SPC) charting, trend analysis across production lots, and export to CSV, PDF, or XML formats. The software supports user-level access control, electronic signature fields, and time-stamped audit trails compliant with FDA 21 CFR Part 11 requirements when deployed in regulated environments. Raw pressure-versus-time curves are stored with metadata (operator ID, calibration date, environmental temperature/humidity), facilitating traceability and root-cause analysis during internal audits or regulatory inspections.
Applications
- Verification of hydrostatic resistance in surgical gowns, isolation gowns, and PPE ensembles prior to sterilization and distribution
- Quality assurance testing of technical textiles for military shelters, marine tarps, and expedition-grade tents
- R&D screening of novel waterproof breathable laminates and nanocoated substrates
- Supplier qualification and incoming material inspection for automotive interior fabrics and filtration media
- Supporting ISO 13485-certified manufacturing processes through documented, repeatable test protocols
FAQ
What is the standard test area used in HD-D020 measurements?
The instrument utilizes a fixed test area of 100 cm² (100 mm diameter), as specified in GB/T 4744–2013 and ISO 811.
Does the HD-D020 support automatic pressure ramping at variable rates?
Yes—the device allows programmable ramp rates between 10 mm H₂O/min and 60 mm H₂O/min, configurable to match specific standard requirements or internal SOPs.
Is calibration certification provided with the instrument?
Each unit ships with a factory calibration report traceable to NIM (National Institute of Metrology, China); optional UKAS-accredited calibration services are available upon request.
Can the HD-D020 be integrated into a LIMS environment?
Via RS-232 or TCP/IP interface, the instrument supports bidirectional communication with validated LIMS platforms using ASTM E1384 or HL7-compliant protocols.
What maintenance intervals are recommended for long-term accuracy?
Pressure transducer recalibration is recommended annually; seal integrity and clamp torque verification should be performed daily prior to use per QA checklist.
