What is BS EN 62435-1 - Long-term storage of electronic semiconductor devices about?  
BS EN 62435 is a European Standard that discusses electronic components. The IEC 62435 series is intended to ensure that adequate reliability is achieved for devices in user applications after long-term storage.
BS EN 62435-1 is the first part of the multi-series that applies to the long-term storage of electronic components.
BS EN 62435-1 on long-term storage covers the terms, definitions, and principles of long-term storage that can be used as an obsolescence mitigation strategy. Long-term storage refers to a duration that can be more than 12 months for products scheduled for long-duration storage. Philosophy, good working practice, and general means to facilitate the successful long-term storage of electronic components are also addressed.
Who is BS EN 62435-1 - Long-term storage of electronic semiconductor devices for? 
BS EN 62435-1 on long-term storage of electronic semiconductor devices is useful for: 
- Manufacturers of electronic semiconductor devices
- Authorities involved with storage, handling, management and inspection of electronic semiconductor devices
- Manufacturers of electronic equipment and components
- Aerospace and automobile industry
- Companies involved in R&D of semiconductor technology
- Product design engineers
- Electronic engineers
Why should you use BS EN 62435-1 - Long-term storage of electronic semiconductor devices?  
Long-term storage is defined as planned storage of components to extend the life-cycle for a duration with the intention of supporting future use. All failures affecting electronic components initiate originally from a mechanism of a mechanical, chemical, electrical type, or a combination of the three types.
BS EN 62435-1 is a document for long-term storage (LTS) of electronic devices drawing on the best long-term storage practices currently known.
BS EN 62435-1 is intended to give practical guide to methods of long-duration storage of electronic components where this is intentional or planned storage of product for a number of years.
BS EN 62435-1 provides mitigation measures from storage hazards such as ageing, poor stock dimensioning, control during storage and freezing of equipment design and functionality.
BS EN 62435-1 can assist you in storing electronic devices for long periods of time, in order to maintain as-received solderability and avoid any degrading impacts to the part over time. Degradation concerns such as moisture, electrostatic fields, ultraviolet light, large temperature changes, airborne pollutants, and outgassing can thus be avoided.
