| Title | Part 21 Report - Switches Built with Adhesive Beyond Its Expiration Date |
| Event Description | TopWorx discovered that switches were built and shipped using adhesive G909 that was beyond its manufacturer's recommended expiration date. Adhesion properties of the expired adhesive cannot be guaranteed against the deleterious effects of seismic events, thermal aging, and high dose radiation. The switches involved were TopWorx M8-24521-P4 shipped on 12 October 2012 and TopWorx M8-2352T-P4 shipped on 8 November 2012. Both shipments were sent to PGS Enrique Maria Hierro S.L. in Spain.
If the units mentioned above are found to be installed in an environment that may expose them to the conditions of seismic events, thermal aging, and/or high dose radiation, then the units should be replaced. Per TopWorx, there were 13 switches shipped. All switches were shipped to Spain. No switches were shipped to US licensees. Technical questions or concerns should be addressed to Alex Murphy, Manager, Quality, (502) 873-4602. |
