To the best of our knowledge, all Harwin products can be rated as MSL Level 1 if required. No Harwin products are electrostatically sensitive (ESD). However, we do also operate a Shelf Life policy for all connector products containing plated components, under the guidelines of the IECQ-BS9000 Approval Standards.
In accordance with Paragraph 1.1.9 of the British Standard: BS 9520 (Generic Approval Procedure for D.C. + L.F. Electrical Connectors) the following applies to ‘Delayed Delivery’ – the time between the manufacture of the connector product and the use of the same product:
Connectors held for a period exceeding 36 months, from acceptance inspection, shall be re-examined.
At Harwin, this revalidation is performed after 24 months from the original date of manufacture. Test parts are subjected to artificial accelerated ageing. The product batch is then acceptable for a further 36 months shelf life. During the period of the 36 month shelf life, the connectors must be stored in acceptable storage conditions, constituting:
The product must be kept in the original sealed Harwin packaging at all times and must retain all date code traceable numbers.
The product must be stored in a suitable environment that is not subjected to extreme variations in temperature and humidity.
