Control of welders (heat sealers)

According to ISO11607-1 & 2: 2018 and EN 868-5 Annex D: 2009

Partner of your quality approach, Hospitec supports you in the regulatory controls of your welders (heat sealers)

The different stages of a welder inspection

1
On-site control
Test of the following points:
- programmed sealing temperature
- programmed sealing pressure
- welding width > 6mm
- absence of grooves, folds, chimneys
- seal intact over the entire width and length of the weld
- no delamination or separation of materials when opening the bags
- no bursting of bags during the sterilisation cycle
2
Control in the measurement laboratory
In the days following the on-site inspection, we carry out pull-out resistance tests in our measurement laboratory on:
- 5 sterilised welds
- 5 unsterilised welds
We thus measure the following data:
- Minimum strain
- Maximum strain
- Medium strain
The ISO11607 standard imposes an average strain value greater than 1.5N

Example of data collected on a resistance test

This report contains, among other things:

A notice of compliance according to the standards
A comparison between the indications of the welder and our measuring instruments
Follow-up with comparison of the results of previous tests
A relevant opinion possibly proposing corrective measures
A detailed conclusion of the entire inspection
