Overview
The Qigao HSY-4985 Petroleum Wax Penetration Tester is a precision mechanical–electronic instrument engineered for standardized determination of penetration depth in semi-solid petroleum waxes and related thermoplastic materials. It operates on the fundamental principle defined in ASTM D1321 and ISO 2855:2019—measuring the vertical distance, in tenths of a millimeter (dmm), that a standardized needle penetrates a specimen under specified load, time, and temperature conditions. Designed in strict compliance with GB/T 4985–2010 (“Standard Test Method for Penetration of Petroleum Waxes”), this tester delivers traceable, repeatable results essential for quality control in wax refining, paraffin manufacturing, candle production, and packaging-grade wax formulation. Its modular architecture supports both needle-based (for waxes, bitumens, greases) and cone-based configurations, enabling method flexibility across GB/T 4509–2010 (asphalt), JTG E20–2011 T0604 (road construction bitumen), and food-grade soft solids per GB 5009.3–2016.
Key Features
- Digital penetration readout with 0.01 mm resolution and ±1 dmm repeatability—calibrated against NIST-traceable reference standards;
- Six pre-programmed timing intervals (5, 8, 10, 12, 30, and 60 seconds), each controlled by a microprocessor-driven electromechanical release with <±0.1 s timing deviation;
- Bidirectional vertical positioning system: motor-assisted coarse lift (±5 mm increments) paired with micrometer-style fine adjustment (0.01 mm resolution) for precise needle–sample alignment;
- Interchangeable needle assembly conforming to GB/T 4985: total mass 2.500 g ±0.05 g, stainless steel shaft, conical tip geometry (9° included angle, 0.3 mm apex radius); optional cone adapters available for ASTM D217 or ISO 2137 testing;
- Integrated cold-light LED illumination and 5× optical magnifier for real-time visual verification of sample surface leveling and needle contact point;
- Self-contained housing with rigid cast-aluminum base, vibration-damped column, and ESD-safe enclosure—designed for benchtop stability in QC labs and field testing units.
Sample Compatibility & Compliance
The HSY-4985 accommodates specimens in standard 55 mm diameter × 35 mm height metal or glass penetration cups (per GB/T 4985 Annex A). It is validated for use with fully solidified paraffin waxes (melting point 45–70 °C), microcrystalline waxes, petrolatum blends, and food-grade lipid matrices including butter, margarine, cheese curds, and confectionery gels. All mechanical components—including needle holder, release solenoid, and vertical guide rails—meet dimensional tolerances specified in ISO/IEC 17025:2017 Clause 6.4 for measurement equipment integrity. The instrument’s design satisfies functional requirements of GLP-compliant environments: no firmware upgradability without audit trail, physical key-lock for parameter locking, and permanent serial-number engraving on chassis and main PCB.
Software & Data Management
This model includes embedded firmware with registered software copyright (Certificate No. 6097415), supporting local data logging of up to 1,000 test records with timestamp, operator ID, ambient temperature, and test duration. Export is via USB 2.0 to CSV format for integration into LIMS platforms. While no remote connectivity or cloud interface is provided, all stored data comply with FDA 21 CFR Part 11 requirements for electronic records: user authentication (4-digit PIN), immutable audit log (date/time/operator/action), and automatic record checksum validation. Raw penetration values are output in dmm (decimillimeters), convertible to SI-aligned mm using built-in scaling factor (1 dmm = 0.1 mm).
Applications
- Quality assurance of petroleum wax feedstocks and finished products in refineries and specialty chemical plants;
- Batch-to-batch consistency verification during candle wax blending and coating wax production;
- Hardness profiling of edible fats and dairy spreads in food R&D and regulatory testing labs;
- Bitumen penetration grading per Chinese highway standard JTG E20–2011 T0604 for pavement binder qualification;
- Research-level correlation studies between penetration depth, crystallinity (via DSC), and thermal shrinkage behavior in polyolefin-modified waxes.
FAQ
Does the HSY-4985 support automated temperature control?
No—the base unit does not include integrated temperature regulation. However, it is fully compatible with external thermostatic baths (5–40 °C range), sold separately, which meet GB/T 4985 Section 5.2 requirements for thermal uniformity (±0.1 °C over sample volume).
Can I use this instrument for asphalt penetration testing?
Yes—when equipped with the optional ASTM D5–compliant 100 g total load kit and 25 mm diameter sample container adapter, it meets JTG E20–2011 T0604 and GB/T 4509–2010 specifications.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate referencing ISO/IEC 17025-accredited third-party verification of needle mass, timing accuracy, and displacement linearity—valid for 12 months from date of manufacture.
What maintenance is required for long-term accuracy?
Monthly cleaning of needle shaft and guide sleeve with anhydrous ethanol; annual verification of solenoid actuation force and vertical axis orthogonality using certified gauge blocks and optical level—procedures detailed in the English-language Operation Manual (Revision 3.1, included).
