The ASSIST database is the official source for specifications and standards used by the US Department of Defense. Indexed documents include current and historical military and federal standards and specifications. The ASSIST document database houses over 180,000 PDF files associated with about 82,000 of the approximately 111,000 indexed documents. (Updates vary)
Examples are:
MIL-STD-810H
MIL-STD-461G

What is the website address?
US DOD provides with a tool called ASSIST QUICK SEARCH for searching for any of the US military standards. ASSIST website has the historic versions of the standards. All can be downloaded free of charge.
US DOD assumes that the cost of the effort for developing standards is met with the tax dollars paid by the people. That is probably the reason why these products are free for anyone. The intended audience therefor is probably the US people.

MIL-STD-810H, US DOD Test Standard, starts with an important phrase at the beginning paragraph of each of the 28 test methods: “Tailoring is Essential.” It is therefore crucial to understand what this means and how to tailor the test methods for specific equipment, considering the platform, mission, and environmental requirements.
GDS Engineering R&D provides MIL-STD-810H training online or onsite. Performing operations in various parts of the world, we have been providing this course to the defence industry strategists, leaders, program managers, projects managers, designers, and test engineers for more than 10 years. With long years of background in test projects in the USA and Turkey, Dr. Cicek, the main lecturer of this training, explains the tailoring concepts with specific examples.
This course provides with information and knowledge of experience on how to develop Concepts of Operations (CONOPS) document and Lice Cycle Environmental Profile (LCEP) to derive operational therefore test requirements for the Equipment Under Test (EUT). Understading the tailoring part of MIL-STD-810H is probably the most important aspect of this test standard training, due to the following reasons:
Developing a test plan for MIL-STD-810H equipment testing might be a confusing and time consuming process.
Training will provide an understanding into why and when CONOPS document is needed and how test requirements are established along with Mission and Environmental profiles of the EUT. These are all covered by both presentations and specific product examples through discussions during the training sessions.
In test method discussions, the instructor discuss “what items” (i.e. test levels) and “how” they will be tailored with specific examples.
Test methods, i.e. temperature, humidity, temperature shock, require mission and environmental profiles are established for successfully determining the test levels, durations, and criteria for pass or fail.
Consider the following for tailoring
A Generalized Task Statement for Tailoring: Condider the environmental effects. An example list is provided with a list below. Develop exposure curves considering exposure scenarios. For this, use/develop CONOPS document and generate a Life Cycle Environmental Profile (LCEP).
Environmental effects (temperature, humidity, icing, etc.) to the equipment in different operational modes: i.e. transportation, operation, and stand-by. Condider these effects with scenarious and develop exposure curves.
Equipment vulnarabilities under the environmental/operational conditions.
Effects caused by the platform operations (vibrations, shock, etc.)
The effect due to the platform environment; various conditions in the section the equipment will be operating. For example, the equipment might be exposed to fluid contamination in the section where it will be installed.
Equipment’s effect to the environment and systems (EMI, vibrations, fluid contamination, fire and flammability, etc.)
Consider risks of operational breakdowns with “what if” scenarios.

Acceleration, as addressed in MIL-STD-810G Method 513.6 (Department of Defense, 2009), is a load factor (inertial load or “g” load) that is applied slowly enough and held steady for a period of time such that the materiel has sufficient time to fully distribute the resulting internal loads to all critical joints and components.
The common methods used to expose equipment to a sustained acceleration load are centrifuge and track/rocket-powered-sled testing.
However, both methods impose limitations on AE equipment testing. For example, the costs required and the scheduling, planning, and coordination phases associated with the use of these types of test facilities are often prohibitive. In some cases, centrifuges and track/rocket sleds may limit the orientations at which the test article can be mounted for testing. To maintain validity, all AE devices are tested under the same mounting configuration as intended for operational use. Finally, due to the often expensive and delicate nature of medical devices, insufficient inventories often prevent the use of these tests due to their somewhat destructive nature.
Because of the difficulties associated with physical dynamic testing, the ATB team initially turned to Finite Element Analysis (FEA) as the method of choice for meeting acceleration test requirements.
Recent technological advances in microcomputing and higher resolution graphics capabilities allowed complex systems to be modeled and simulated for both static and dynamic tests.
The FEA techniques were already used by others for various aircraft structures and devices. For example, Foster and Sarwade (2005) performed an FEA of a structure that attached medical devices to a litter. This structure was later approved as STF. Continuing on the same theme, Lawrence, Fasanella, Tabiei, Brinkley, and Shemwell (2008) studied a crash test dummy model for NASA’s Orion crew module landings using FEA. Viisoreanu, Rutman, and Cassatt (1999) reported their findings for the analysis of the aircraft cargo net barrier using FEA. Furthermore, Motevalli and Noureddine (1998) used an FEA model of a fuselage section to simulate the aircraft cabin environment in air turbulence. These and similar studies demonstrated the successful use of the FEA method to verify requirements by analysis for an acceleration test.
Given the costs associated with dynamic testing, the ATB originally envisioned using the FEA method to alleviate budget and inventory concerns. To test this theory, the ATB employed FEA for testing various AE structures to meet the acceleration requirements and found some aspects of this method to be cost- and time-prohibitive.
Lessons learned from these studies are provided in the case-studies section. The various types of analysis and test methods raise questions as to what the correct decision process is for selecting the most appropriate method for STF testing of AE equipment.
The authors of this article describe the process developed and employed by the ATB for the acceleration testing of AE equipment since June 2008.
The ATB’s process has proven to be well suited for identifying the most appropriate test method—one that not only represents the most appropriate and effective test method, but also minimizes the use of available resources. This process includes testing both structurally simple and complex equipment and successfully introducing the use of the Equivalent Load Testing (ELT) method, which permits the use of alternative testing approaches, such as pull testing and tensile testing.
