Overview

EN 14850:2005 (CEN) specifies a standardized method for measuring the contact height of the compression closure between an aerosol valve cup and a metal aerosol container with a 25,4 mm aperture (one inch). The contact height measurement is used to adjust clinching (crimping) tooling and to monitor production uniformity and safety of the valve-to-aperture seal. While essential for tooling adjustment and quality control, the standard notes that contact height alone is not sufficient to guarantee a safe seal.

Key topics and technical requirements

• Scope: Applies to metal aerosol containers with 25,4 mm apertures as defined in EN 14847 and prEN 15006, fitted with valve cups per EN 14848.
• Definition: Contact height is the distance between the plane of the top lip of the aperture and the centre of the radius of curvature of the clinching jaws when fixing the valve cup.
• Measuring apparatus: A dedicated instrument that reproduces clinching conditions (jaw diameter 27,1 mm; internal aperture D = 25,4 mm). The measuring tip radius r is defined by the formula r = R + t, where R = 1,2 mm (jaw radius) and t = 0,3 mm (cup wall thickness), giving an effective tip radius of 1,5 mm. The instrument has a constant offset of 0,35 mm.
• Procedure:
  • Replace clinching tool tips with the measuring instrument and position the tip at the point of direct internal contact.
  • Adjust the instrument to zero using a setting piece before testing.
  • Measure contact height at three equidistant points around the aperture; report the arithmetic mean and record maximum and minimum readings.
  • The contact element is spring‑loaded to maintain consistent contact.
• Test report must include: number and type of containers tested, equipment used, counts of satisfactory/unsatisfactory containers (per EN 14847 and prEN 15006), and date of testing.

Applications and who uses it

• Packaging engineers and tooling technicians - set and verify clinching jaw adjustments during production setup and maintenance.
• Quality assurance / QC laboratories - perform routine checks to monitor process stability and product uniformity.
• Aerosol container manufacturers and converters - verify compatibility between valve cups and container apertures.
• Compliance officers and test labs - document measurement results for regulatory or customer specifications.

Practical benefits include improved assembly consistency, reduced leak or sealing failures, and standardized reporting for production control.
