<\/figure>\n\n\n\nIndustry-Specific Leak Tests<\/h2>\n\n\n\nAutomotive<\/h3>\n\n\n\n
The engines, fuel injectors, transmissions, and cooling systems of cars and buses need to be tested and retested before going to market.<\/p>\n\n\n\n
Medical<\/h3>\n\n\n\n
Whether it\u2019s for a regular check-up or a serious surgery, patients need to know the medical equipment being used can provide the best care. Extensive leak testing ensures this reliability.<\/p>\n\n\n\n
Industrial<\/h3>\n\n\n\n
Industrial companies rely on tests to identify product flaws and faults. Leak tests are used on a variety of household and daily systems: beverage dispensers, coffee makers, faucets, and more.<\/p>\n\n\n\n
Packaging<\/h3>\n\n\n\n
From kids\u2019 applesauce to sterile surgical items, packaging must be leak-free to preserve safety and product quality.<\/p>\n\n\n\n
We Need Leak Tests<\/h2>\n\n\n\n
Leak testing is an integral step in the manufacturing process. Without it, consumers could be exposed to faulty, unsafe, or hazardous products.<\/p>\n\n\n\n
What Is a Leak Test?<\/h2>\n\n\n\n
Leak testing determines if an object, product, or system functions within a specified leak range. Air leak testers use pressure to generate and monitor flow from high to low pressure to detect any leaks.<\/p>\n\n\n\n
How to Calculate Leak Rate (SCCM)<\/h2>\n\n\n\n
A leak rate is expressed as a volume per unit of time:<\/p>\n\n\n\n
ATM<\/strong> = Atmospheric pressure (PSIA)<\/p>\n\n\n\n V<\/strong> = Test volume (cm\u00b3)<\/p>\n\n\n\n \u0394p<\/strong> = Pressure decay during test<\/p>\n\n\n\n \u0394t<\/strong> = Time of decay (min)<\/p>\n\n\n\n Formula:<\/strong> Leak rate = \u0394p\/\u0394t * V \/ ATM<\/p>\n\n\n\n Example:<\/strong> Air leak detection is an essential step in manufacturing. Common tests include:<\/p>\n\n\n\n Pressure Decay (PD)<\/p>\n\n\n\n Vacuum Decay (VD)<\/p>\n\n\n\n Occlusion (Occ)<\/p>\n\n\n\n Mass Flow (F)<\/p>\n\n\n\n Burst (B)<\/p>\n\n\n\n Crack (C)<\/p>\n\n\n\n Chamber (PR)<\/p>\n\n\n\n Used for small, sealed components with a single access port. A drop in pressure over time indicates a leak.<\/p>\n\n\n\n Measures flow through a part with two open ports. Fails if flow rate is outside standard limits.<\/p>\n\n\n\n Backpressure Flow<\/p>\n\n\n\n Pressure Increase<\/p>\n\n\n\n Valve Reseat<\/p>\n\n\n\n Creep\/Ramping Fill<\/p>\n\n\n\n Pressure Exercise<\/p>\n\n\n\n Vacuum Exercise<\/p>\n\n\n\n Bubble\/Submersion<\/p>\n\n\n\n Hard Vacuum (Helium)<\/p>\n\n\n\n Helium Accumulation, Sniff, or Spray<\/p>\n\n\n\n Tracer Gas<\/p>\n\n\n\n Ultrasonic<\/p>\n\n\n\n A leak is an unintended escape of gas or fluid. It can be caused by cracks, holes, or even material permeability.<\/p>\n\n\n\n Gross Leak:<\/strong> Large, visible, easy to detect.<\/p>\n\n\n\n Fine Leak:<\/strong> Small, requires sensitive tools.<\/p>\n\n\n\n Permeation Leak:<\/strong> Molecular-level flow through material.<\/p>\n\n\n\n Pressure Decay Testing<\/p>\n\n\n\n Mass Spectrometry<\/p>\n\n\n\n Bubble Testing<\/p>\n\n\n\n Ultrasonic Testing<\/p>\n\n\n\n Helium Leak Testing<\/p>\n\n\n\n Hydrostatic Testing<\/p>\n\n\n\n Vacuum Testing<\/p>\n\n\n\n Dye Penetrant Testing<\/p>\n\n\n\n Acoustic Emission Testing<\/p>\n\n\n\n Infrared Thermography<\/p>\n\n\n\n This method is effective, simple, and non-destructive. The product is sealed and pressurized. If pressure drops, a leak is present.<\/p>\n\n\n\n Cost-Efficient<\/p>\n\n\n\n Fast Results<\/p>\n\n\n\n Easy Setup<\/p>\n\n\n\n Minimal Resources<\/p>\n\n\n\n Highly Accurate Data<\/p>\n\n\n\n Non-Invasive<\/p>\n\n\n\n Streamlined Production<\/p>\n\n\n\n Automotive & Aerospace:<\/strong> Fuel tanks, radiators, AC systems.<\/p>\n\n\n\n Electronics:<\/strong> Smartphones, sensors, batteries.<\/p>\n\n\n\n Medical:<\/strong> Infusion pumps, catheters, drug vials.<\/p>\n\n\n\n HVAC:<\/strong> Leak-free, energy-efficient systems.<\/p>\n\n\n\n Packaging:<\/strong> Seal integrity for food and pharma.<\/p>\n\n\n\n Chemicals:<\/strong> Safe containment and transport.<\/p>\n\n\n\n Part’s Intended Function<\/p>\n\n\n\n Tested Medium<\/p>\n\n\n\n Material Compatibility<\/p>\n\n\n\n Pressure Range<\/p>\n\n\n\n Internal Volume<\/p>\n\n\n\n Design Complexity<\/p>\n\n\n\n Technological Advances<\/p>\n\n\n\n Operator Training<\/p>\n\n\n\n Environmental Factors<\/p>\n\n\n\n Acceptable Leak Rate<\/p>\n\n\n\n Regulatory Compliance<\/p>\n\n\n\n Record-Keeping<\/p>\n\n\n\n Leak testing ensures safety, reliability, and compliance. It’s about product quality as well as environmental responsibility.<\/p>\n\n\n\n Gas leaks, such as natural gas or air, are the most common.<\/p>\n\n\n\n A test that introduces a substance to detect leaks by observing its presence.<\/p>\n\n\n\n Uses vacuum or pressure differential to detect leaks by air ingress.<\/p>\n\n\n\n Detects leaks using compressed air and monitoring for pressure change.<\/p>\n\n\n\n Advanced technology enables better accuracy, automation, and efficiency.<\/p>\n\n\n\n Product failure, safety hazards, environmental pollution, and recalls.<\/p>\n\n\n\n It varies by industry, regulation, and product criticality, but should be done regularly.<\/p>\n\n\n\n We have strategically grown over the decades to carry a comprehensive suite of Leak and Seal Strength Tester<\/a>,Paper Board Tester<\/a>,Adhesiveness Tester<\/a>,Plastics Testing<\/a>,Leak Test Equipment<\/a>,Medical Device Testing<\/a>,Container Testing<\/a>,Electronics Testing<\/a> products and services to better serve clients\u2019 business requirements.
