Test Method 527.1 Multi-Exciter Test Method 528.1 Mechanical Vibrations of Shipboard Equipment (Type I – Environmental and Type II – Internally Excited) MIL-STD-810, Part three - World climatic regions Part Three contains a compendium of climatic data and guidance assembled from several sources, including AR 70-38, Research, Development, Test and Evaluation of Materiel for Extreme Climatic Conditions (1979), a draft version of AR 70-38 (1990) that was developed using Air Land Battlefield Environment (ALBE) report information, Environmental Factors and Standards for Atmospheric Obscurants, Climate, and Terrain (1987), and MIL-HDBK-310, Global Climatic Data for Developing Military Products. It also provides planning guidance for realistic consideration (i.e., starting points) of climatic conditions in various regions throughout the world. Applicability to "ruggedized" consumer products U.S. MIL-STD-810 is a flexible standard that allows users to tailor test methods to fit the application. As a result, a vendor's claims of "...compliance to U.S. MIL-STD-810..." can be misleading, because no commercial organization or agency certifies compliance, commercial vendors can create the test methods or approaches to fit their product. Suppliers can — and some do — take significant latitude with how they test their products, and how they report the test results. When queried, many manufacturers will admit no testing has actually been done and that the product is only designed/engineered/built-to comply with the standard. This is because many of the tests described can be expensive to perform and usually require special facilities. Consumers who require rugged products should verify which test methods that compliance is claimed against and which parameter limits were selected for testing. Also, if some testing was actually done they would have to specify: (i) against which test methods of the standard the
