   Failure Analysis / Troubleshooting       Failure analysis is the evaluation of a product and product failure to determine the underlying cause of the failure. Failure analysis results are used to correct design flaws. Troubleshooting is diagnostic or corrective maintenance performed to correct an existing problem. 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. 
   Evaluation / Inspection       Evaluation or inspection is the process used to determine if a product, service, component, facility, or quality system meets specific standards, performance criteria or OEM specific requirements. 
   Field Evaluation / On-site Inspection       Company provides field evaluations or on-site inspections at the supplier's facility or at the site of the supplier's activity. 
   In-process / In-line Testing       Company offers in-process or in-line testing so that products can be tested in functional environments. 
   Reliability / Robustness       Reliability or robustness measures a system's invulnerability to potentially corrupting influences. This testing is especially important when components in a system fail. 
   Test Development       Company develops tests and protocols for custom or proprietary parts and systems. 
   Test Fixtures / Equipment       Company offers design and fabrication services, test fixtures, test equipment, or test facilities for specific applications. 
   Test Panel / Sample Prep       Test panel and sample preparation services 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 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 Offered       
   Your choices are...         
   Aging / Life Testing       Company performs aging or life testing. 
   Condition Monitoring       Condition monitoring and machine maintenance services monitor the condition of machines, processes and rotary equipment.  Condition monitoring and related services under this category include: ferrography or oil analysis (lubricant testing) alignment, position, balance evaluation and correction, and ultrasonic fault detection. Other preventive machine maintenance services are repairs, part replacements, or lubrication replenishment performed on a regular time based schedule. Condition monitoring and machine maintenance services providers often perform predictive maintenance (PdM) and/or preventive maintenance to maintain reliability, avoid loss of life, and prevent costly, unplanned plant or machine shutdowns. 
   Fatigue / Endurance       Company offers 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. 
   Fire Characteristics / Flammability Testing       Company offers fire characteristics including flame and heat resistance, smoke development, and the toxicity of combustible products. 
   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 phenomenon occurring such turbulent flow, cavitation, or laminar flow. 
   Fungus / Biofouling       Company offers products or components to determine resistance to fungal growth or biofouling. 
   Leak / Seal       Company tests or inspects packages, products or equipment to ensure integrity against leaks. 
   Mechanical / Structural (Statics)       Company provides mechanical and structural testing or inspection for stress, strain, load, shear strength, etc. 
   NDT / Inspection       Company offers nondestructive testing (NDT) or inspection services. 
   Oil Analysis / Fluids Testing       Oil analysis and fluids testing encompasses the evaluation of oils, fuels, lubricants, coolants, greases, EDM fluids, transformer insulating oils and other industrial fluids using a variety of tests. Testing can include ferrography, viscosity (stokes or kinematic), elemental analysis, spectroscopy (FT-IR, GC-MS), crackle, oxidation, foam, determination of drop point, % sediment, particle count, dielectric strength, specific gravity, surface tension, water content, pour point, cloud point, and other specific fluid properties effecting machine performance or equipment operation. Ferrography is the separation and analysis of metallic (ferrous or ferromagnetic) wear particles from a lubricant or fluid. Ferrography or wear particle analysis is used to monitor lubricant or machine condition. 
   Performance Testing       Performance testing evaluates the compliance of a system or component with specified performance requirements. 
   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.  
   Safety / Liability Testing       There are two types of electrical safety tests: type tests and routine production tests. Type tests are performed during the approvals process by test houses. Routine production tests are performed at each end of the production line by the manufacturer. 
   Shock Testing       Company offers shock mode vibration testing services. 
   Thermal Cycling / Shock       Company offers 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.
