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.
FAA provides guides for exlaining the equipment process in the guide document called “THE FAA AND INDUSTRY GUIDE TO PRODUCT CERTIFICATION (CPI Guide), 3rd Ed.”. The document intends to inform the industry with the certification process to improve safety, teamwork, planning, accountability, quality, and continues improvement.
This post is to summarize the important sections of this document for an overview. The complete manuscript should be referred for formal studies and initiations.
The most important message given in this document is that the certification process requires partnership for ensuring the safety. Elements of ensuring safety is self evaluating the compliance level through Compliance Maturity and arranging partnership with FAA through the Partnership for Safety Plan as layed out in the aforementioned document.
Compliance Maturity
FAA desribes the compliance maturity as a measure of the ability of an Applicant to perform the required compliance activities with a minimum level of FAA involvement. It provides the FAA with the assurance that they can move from direct involvement on most project tasks to an oversight role. There is an expectation that Industry will embrace a compliance maturity culture of ever advancing compliance competencies.
Partnership for Safety Plan
The PSP is a written “umbrella” agreement between the FAA and the Applicant that focuses on high level objectives such as open and effective communication, key principles including effective certification programs utilizing the Project Specific Certification Plan (PSCP), designee utilization if applicable, issue resolution, continuous improvement, general expectations, and other agreements reached between the Applicant and the FAA that further Applicant maturity.
The PSP also helps define the general discipline and methodology to be used in planning and administering certification projects using appropriate procedures. Although the stated procedures are not required, the procedures provide a means to help the Holder/Applicant move toward a more systematic process for conducting projects that the FAA can rely on without having to do direct oversight of the projects.
Partnership for Safety Plan is an umbrella agreement that covers the following specific activity areas:
Continued Operational Safety
Project Specific Certification Plan
Risk Based Level of Project Involvement
Continuous Improvement
Issues Resolution Process
Other as defined by the PSP
Project Specific Certification Plan (PSCP)
Developed based on the needs of the project as defined in paragraph 2-3.d of FAA Order 8110.4, the PSCP must provide clarity for how the Applicant will comply with the regulations. The PSCP is a key tool in meeting the 14 CFR part 21 requirements for the certification and approval of a product.
Test Standard: RTCA-DO-160G
RTCA-DO-160G is the current test standard version to use for equipment certification testing. Everything airborne from small general aviation aircraft and rotary aircraft to large airliners and transport planes must go through DO-160 testing. The DO-160 standard and the EUROCAE ED-14 standard are identically worded. DO-160 standard procedures van be used in either FAA or EASA certification projects. The catergories, procedures, and test parameters are derived from FAA regulations and for most of the procedures there is a direct reference.
DO-160 testing involves a wide range of factors, from humidity and temperature to electrical interference and shock resistance. The standard is intended to cover almost anything that can disrupt the performance of an airborne electrical or electronic device. By undergoing the certification and testing process, a DO-160 compliant device can deliver reliable and accurate operation in any flight condition.
GDS Engineering R&D provides training on the RTCA-DO-160G testing. Part 21 process and all tests in DO-160 are covered in this short two and a half day training.

Devices used onboard a ship are exposed to harsh electromagnetic environments, whether in the propulsion, deck or bridge area of a ship. Testing of such devices for Electro-Magnetic Compatibility (EMC) is therefore very important. Otherwise, manufacturers can face difficulties during the certification and procurement stages.
EMC testing and certification services to ensure your marine products comply with relevant international standards and regulations is a MUST!
GDS Engineering R&D does not perform these tests yet; however, have the information on design and test knowledge. The requirements include the international conventions as agreed by the International Maritime Organization (IMO) for Safety of Life at Sea (SOLAS).
Currently, we have observed that these tests are conducted by reputable agencies like ELEMENT.
The testing laboratories use the following standards to test the marine electronic, digital or electrical devices for certification to IMO SOLAS requirements, guidance, or recommendations:
IEC 60945
IEC 60533
Lloyds Register Test Spec No 1
DNV Certification Notes 2.4
IEC 60092

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.
