Child safety - force to extract lighter

16 May 2019

Solution

  • Software-controlled test stand and software
  • Clamping fixtures and accessories designed for the product tested

Benefits

  • Approved product safety testing to customer specification
  • Simple and reliable test procedure
  • Verstility to create other programs for R&D

Requirement

The customer manufactures lighters and is currently developing a case/guard designed to increase the safety for children.

The test consists of checking the minimum pull-off force necessary to extract the lighter from the guard at a 2.5 mm/min speed. The extraction force (no lower than 50N) would need to be measured from the strongest element predetermined by the manufacturer (the wheel).

As part of an R&D project, the customer required a system which would offer versatility in the test and calculation program. The data and the graphic representation would also need to be captured at a high resolution, i.e. 2000 Hz.

Solution

As per specification, Mecmesin supplied the Imperial computer-controlled test system with an intelligent loadcell able to capture data at 2000Hz.

A special accessory, developed by the client, holds the patented child-guard vertically. The holding accessory fixed to the anvil plate of the test stand, keeps the sample in the loadcell axis. A crocodile clip, attached to the loadcell via an extension rod, is gripping the wheel of the lighter. At a 2.5 mm/min speed, and an average of 50N, the crocodile clip pull-off wheel and the lighter slides from the wall of the patented child-guard.

Test equipment

  • Imperial 1000 Computer-Controlled Stand
  • ILC 500 N
  • Extension Rod
  • Special Holding Fixture (developed by customer)
  • Crocodile Grip (supplied by customer)
