Flow and pressure (fluid dynamics) testing services evaluate the flow, pressure and fluid dynamics of components and products such as radiators, heater cores, lines and bottles. Typically, they perform a battery of tests in accordance with published standards from organizations such as Underwriters Laboratories (UL), the European Community (CE), and the International Standards Organization (ISO). Flow and pressure testing (fluid dynamics) is a subset of product and component testing, a larger category that includes electrical, life, environmental, exposure, dynamic, ergonomic and other specialized tests. Common capabilities of flow and pressure (fluid dynamics) testing services include research and development, component and product comparison, evaluation and troubleshooting, data acquisition and instrumentation, test development, sample preparation, training, certification, and in-process or in-line testing. Testing such as failure mode and effects analysis (FMEA) is also available.
Flow and pressure testing (fluid dynamics) services perform a variety of functions. Examples include acoustic testing and particle impact noise detection (PIND), chemical and biochemical compatibility testing, design verification testing (DVT), nondestructive testing (NDT), and loss of coolant accident (LOCA) testing. Tests are also used to determine the effects of abrasion, aging, altitude, biofouling, bounce, creep, decompression, ergonomics, fatigue, fire, humidity, pyrotechnic shock, radiation, sterilization, stress, thermal cycling, ultraviolet light and weathering. Accelerated testing and screening includes highly accelerated life testing (HALT) and highly accelerated stress screening (HASS). The results from HALT testing are used to set test limits for production screening or HASS tests. Network-equipment-building system (NEBS) compliance tests subject anchors to load cycles of varying magnitude and frequency to simulate seismic events.
Flow and pressure testing (fluid dynamics) services test many types of products. Examples include aerospace and avionics equipment, appliances, automotive parts, building products, commercial food equipment, consumer electronics, food and drugs, electrical distribution devices, combustion and hazardous location equipment, health care and medical devices, lighting products, industrial equipment and machinery, instrument sensors, and both information technology (IT) and telecommunications products. Flow and pressure testing (fluid dynamics) services also test laboratory equipment, marine equipment, motors and motor controllers, packaging products, semiconductors, integrated circuits (ICs), plumbing products, radio frequency (RF) and wireless devices, and components and finished products made of rubber and plastic.
There are many national and international approvals and certifications for flow and pressure testing (fluid dynamics) services. These include but are not limited to the CE Mark (Europe), S Mark (Europe), FCC (US), FDA (US), ASTM (US), VCCI (Japan), DENAN (Japan), TUV-GS (Germany), GS Mark (Germany), EZU (Czechoslovakia), RLL (Korea), PCBC (Poland), C-TICK (Australia), PSB (Singapore), IRAM (Argentina), NOM (Mexico), SABS (South Africa), GOST (Russia), T Mark (Taiwan), BSMI (Taiwan), and the CSA Mark (Canada). International organizations that provide certifications and approvals include ISO and UL as well as the International Electrotechnical Commission (IEC), the Institute of Electrical and Electronics Engineers (IEEE), the International State Transit Association (ISTA), and the Unites States Pharmacopeia (USP). Companies that meet U.S. government military specifications (MIL-SPEC) also provide flow and testing services.
Flow and pressure testing (fluid dynamics) services vary in terms of facility accreditations and assessments. Standards organizations include but are not limited to the FCC (US), FDA (US), SCC (Canada), CNAL (China), METI (Japan), VCCI (Japan), and KETI (Korea). The American Association for Laboratory Accreditation (A2LA), the American National Standards Institute (ANSI), and the National Voluntary Laboratory Accreditation Program (NVLAP) also provide facility accreditations and assessments.
