The reliable operation of complex electronic communications, control and armament systems in extreme environments demands stringent design criteria and careful validation. Severe shock, vibration, heat, humidity and airborne contaminants are common in land, sea and air platforms.
Mention the word “environment” to most people and they think of air pollution, soot, contaminated beaches, etc. Those certainly are problems we must all consider, but I’m using the word “environment” differently here.
In the Summer of 2000 I booked some burn time at a small environmental lab in south Dallas. The facility was not exactly state-of-the-art, but the price was right: $300 a burn. It sure beat paying about $4,000 a burn at an NRTL at the time. For 300 bucks, you got the chamber, a methane line burner connected by a hose to a big tank of methane gas, and a technician who would manually operate the whole thing from an adjoining isolated room. A fire extinguisher was always ready “just in case”.
This is the last in a three part review of the newly released MIL-STD-464C, “Electromagnetic Environmental Effects Requirements for Systems.” The following is a summary of Parts 1 and 2 of the review, then on to new material.

The compliance world was shaken up in 2005 with the realization that the European Union was enacting legislation that would require manufacturers wishing to sell their electrical or electronic products in the EU to reduce the environmental impact of these products through design. The practice of eco design was to be enshrined in Law and many companies who would not normally have considered the environmental impact of their products now faced the prospect of being legally obliged to do so. Since the introduction of this legislation, in the form of the Energy using Products Directive, industry has been monitoring its phased implementation to see to what degree the requirements will affect their designs. Following a summary of the scope and major features of the legislation, this article will review the latest developments in the implementation process and give an overview of the emerging design requirements. It will go on to discuss the important areas of conformity assessment, market surveillance and enforcement and conclude by looking at possible future developments and discuss to what degree the legislation fulfils the goal of reducing environmental impacts.
