what a good question. I think I understand your situation, with so much to know where do you begin?
Numerous websites take the process from step 2 onwards but step 1 is the concept which may not be obvious to the non-technical person. It will help if the person has a grasp of basic science, that is electricity, heat, mechanics. Try this approach: For a non technical person it is the simple issues that have to be underlined. First, step outside your company operations; try to see the product you make as just one item in a system of hardware; the customer needs the whole system to run reliably with minimal downtime. That mean everyone's products have to link up without unforeseen interactions, with robustness to operator error; it has to keep working when lightning strikes and restart safely after a power outage. It mustn't burst into flames when abused; mustn't interfere with allocated radio frequencies, telephones, video cameras etc,; mustn't kill the service engineer; must be insurable................. Can the equipment fail? How? Who pays to fix it? Can someone be injured while installing operating or servicing? Can connected equipment be damaged? Can it degrade the performance of another item nearby? How to avoid the cost of equipment failure and repair. How to avoid the cost of injury to the installer, operator and service engineer. How to avoid the cost of explosive damage and consequential loss. How to avoid the cost of installation debugging due to interactions. Regulatory bodies exist to raise the standard of hardware so that beginning at the design stage new equipment gets built incorporating all the knowledge gained from prior experience about reliability and performance. There are three categories of concern: safety: legal liability arising from electrical shock hazard and fire hazard performance: where is it used? a submarine? an aircraft? an office? what are the build requirements and maintenance requirements for the expected life cycle? interaction: what are the requirements to perform reliably in hostile electrical environments such as RF fields, lightning strikes? What are the requirements to limit the emission of nuisance energy which might adversely affect connected equipment and or nearby equipment? ........... better stop there ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
