Help with Flow and Pressure (Fluid Dynamics) Testing Services specifications:

Capabilities

	Capabilities
	Your choices are...
	Testing / Simulation		Suppliers that inspect existing in-service or newly fabricated products through environmental exposure testing, dynamics testing, nondestructive testing (NDT), visual inspection, chemical analysis or structural material testing.
	Certification / Qualification / Commissioning		Suppliers that provide certification, qualification or commissioning services.
	Component / Product Comparison		Suppliers that compare the performance of components or products.
	In-process / In-line Testing		Suppliers that offer in-process or in-line testing so products can be tested in functional environments.
	Engineering / Design Verification (DVT)		Suppliers provide engineering verification including basic functional testing, parametric measurements, and specification verification.  Design verification testing (DVT) is a rigorous process, which subjects the product to repeated functional, temperature, shock, vibration, and exception testing.
	Evaluation / Troubleshooting (FMEA)		Troubleshooting is diagnostic or corrective maintenance performed to correct existing problems. This differs from preventive maintenance, which is performed proactively in order to prevent system problems. Failure mode and effects analysis (FMEA) is a specialized methodology for analyzing failures.
	Research and Development		Research and development services providers perform original investigations (research) to gain new knowledge, and/or apply research findings to create new or significantly improved products or processes (development).
	Test Development		Suppliers that develop tests and protocols for custom or proprietary parts and systems.
	Test Fixtures / Equipment		Suppliers that offer design and fabrication services, test fixtures, test equipment, or test facilities for specific applications.
	Test Panel / Sample Prep		Test panel and sample preparation services providers simulate the effects of various products (paint, coatings, lubricants, etc.), upon test samples. These companies are generally used when it is not feasible to test the effects these items would have on complete products or systems.
	Specialty / Other		Other unlisted capabilities.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Services

	Services
	Your choices are...
	Aging / Life Testing		Suppliers perform aging or life testing.
	Altitude Simulation		Suppliers simulate high altitude conditions to test products needed to function in extreme temperature and low in low oxygen.
	Computational Fluid Dynamics (CFD)		Supplier has the capability to evaluate or simulate fluid systems or components using computational fluid dynamics (CFD).
	Decompression / Vacuum		Supplier simulate exposure to a vacuum atmosphere or to explosive decompression.
	Fatigue / Endurance		Suppliers test fatigue based on cyclic loads, which is a method used to determine the behavior of materials under fluctuating loads. Specified mean loads (which may be zero) or alternating loads are applied to a specimen and the number of cycles required to produce failure (fatigue life) is recorded. Generally, tests are repeated with identical specimens and various fluctuating loads. Loads may be applied axially, in torsion, or in flexure. The net stress in the specimen may be in one direction through the loading cycle, or may reverse direction, depending on the amplitude of the mean and cyclic load. Data from fatigue testing is often presented in an S-N diagram, which is a plot of the number of cycles required to cause failure in a specimen against the amplitude of the cyclical stress developed. The cyclical stress represented may be stress amplitude, maximum stress or minimum stress. Each curve in the diagram represents a constant mean stress. Most fatigue tests are conducted in flexure, rotating beam, or vibratory type machines.
	Flow Testing		Flow tests are commonly used in evaluations of hydraulic, pneumatic, hydrogen, fuel cell and gas handling equipment.  Flow tests evaluate the speed at which fluid (liquid or gas) can move through tubing, pipe, hose, piping system, mixers, pumps, valves and other fluid handling components.  Flow testing may also examine the type of flow phenomena occurring such turbulent flow, cavitation or laminar flow.
	Fungus / Biofouling		Testing products or components to determine resistance to fungal growth or biofouling.
	Gunfire / Pyrotechnic Shock		Suppliers simulate the effects of gunfire or pyrotechnic shock conditions.
	Leak / Seal Testing		Suppliers test packages to ensure integrity against leaks.
	NDT / Inspection		Suppliers provide nondestructive testing or inspection services.
	Pressure / Hydrostatic Testing		Pressure testing includes pressurized liquid or gas exposure, hydrostatic burst tests, pressure rating determination, and identification of changes occurring at high pressures. Pressure tests are commonly used to evaluate hydraulic, pneumatic, or gas handling equipment.
	Thermal Cycling / Shock		Suppliers offer thermal cycling or thermal shock testing services. Repeated hot and cold cycles (thermal cycling) or rapid temperature changes (thermal shock) can result in high levels of cyclic stress due to thermal expansion.
	Specialty / Other
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
