Spray Rating Tester
Püskürtmeli Su İticilik Cihazı
Surface wetting resistance of fabrics.
Model technical data
- Determines the resistance of water-repellent treated fabrics to water and wetting by the spray method.
- A defined volume of distilled or fully deionised water is sprayed onto the specimen from a set distance.
- The wetting grade is determined by comparing the specimen with the defined standard images.
Physical specifications and utilities
| Electrical supply | Manual / passive base apparatus; no mains supply assumed. |
|---|---|
| Power / connected load | Approx. 0 W connected load for preliminary planning. |
| Overall instrument dimensions | Approx. 350 × 350 × 700 mm (W × D × H). |
| Instrument weight | Approx. 5–10 kg net. |
| Gross / shipping weight | Approx. 15.5–22.5 kg gross; estimated packing allowance. |
| Lab requirements | Water specified by the selected method and a collection vessel; compressed air is not assumed. |
Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.
Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.
Product technical specifications and images may vary according to manufacturing conditions and applicable standards.
Test and configuration
- Measured output / function
- Surface wetting grade; not a hydrostatic pressure measurement
- Parameters selected for the method
- Water quality, volume, nozzle and specimen angle
- Verification points
- Spray nozzle, volume and distance
Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.
Test parameters for the reviewed method
Values belong to the stated source edition. Test recipe, fixture and delivered instrument configuration are selected together.
ISO 4920:2012 · 5.1-5.4 / 8.3
- Water volume: 250 ± 2 ml; spray duration: 25-30 s.
- Specimen orientation: 45°; vertical distance between nozzle centre and test-area centre: 150 ± 2 mm.
- Nozzle: 19 holes; hole diameter: 0.86 ± 0.05 mm.
AATCC 22-2005 · 7.1, 8.1-8.4
- Three 180 × 180 mm specimens; retaining-hoop diameter 152.4 mm. Spray 250 mL distilled water at 27 ± 1 °C over 25-30 s.
Control and recording specification
The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.
- The need for integrated software depends on the method and selected hardware; manual instruments use an external test record.
- Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
- The calculation and endpoint are defined by the selected method edition; instrument signals and operator assessments are kept distinct.
- Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
- Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
