Overview
ISO 18599:2015 specifies the dimensions, execution and designation of strips used for water nozzle solidification in textile machinery. The standard defines symbols, preferred sizes, nozzle geometries and marking rules so that jet strips are manufactured and identified consistently for use in textile equipment.
Key topics and technical requirements
- Scope: Dimensions and execution of jet strips for water nozzle solidification, plus the designation format stamped on the nozzle.
- Strip dimensions: Preferred strip widths include 18 mm and 25.4 mm; thicknesses 0.8 mm and 1.0 mm. Terminating radii are given (9 mm and 12.7 mm) and expansion drilling diameter is 6.5 mm.
- Nozzle sizes and geometry:
- Nozzle diameters (D): 0.07 mm to 0.16 mm (preferred sizes listed).
- Nozzle length ratio (l/D): ratios of 0.8, 1.0, 1.2 and 1.5 are specified.
- The standard includes figures showing single-, double- and triple-row strip layouts (r = 1, 2, 3).
- Row spacing and nozzle pitch:
- Distance between nozzle rows (s_r): 0.6 mm, 0.8 mm, 1.0 mm and 1.2 mm are specified.
- The document provides the method (formula) to calculate the number of nozzles per metre based on nozzle spacing.
- Manufacturing tolerances:
- Straightness and parallelism requirements are specified and illustrated (tolerances are shown in the standard figures).
- Material and hardness:
- Jet strips shall be manufactured from stainless steel with a minimum Vickers hardness (HV) of 140.
- Designation and marking:
- The standard prescribes a designation format (ISO 18599 …) and the order of data to be stamped on the nozzle: nozzle diameter, nozzle distance, distance of nozzle rows, thickness, length of nozzle rows, and overall width.
Applications and who uses ISO 18599
- Textile machinery manufacturers (OEMs) use the standard to design and specify jet-strip components that meet consistent mechanical and dimensional criteria.
- Component suppliers and precision machining shops apply the dimensions, nozzle ratios and hardness requirement to produce compatible strips.
- Procurement and specification engineers reference the designation rules to ensure correct ordering and interchangeability.
- Quality assurance and inspection teams use the straightness/parallelism and hardness limits for acceptance testing.
- Useful wherever controlled water-jet solidification is applied in textile processes that rely on precise nozzle performance.
