  • Sensitive Sunscreen Test: Rheological Tests Measure Linear Viscoelasticity to Analyze Lotion
    Rheological tests can determine how resistant lotion is to sun and friction.
  • Lubricity of Materials and Solutions
    Coefficient of Friction (CoF) is used to quantify how readily two surfaces slide in the presence of a lubricant or oil. Conventional CoF tests use custom built hardware to measure the friction but no robust standardized approach is currently available and sensitivity and resolution are problematic
  • KOSME - Pneumatic Cylinder in Bottling Equipment Case Study
    Can an H1 lubricant eliminate stick-slip friction on. the cylinder application? Can this lubricant prove to be compatible with EPDM elastomer? Will this lubricant pass KOSME's accelerated wear testing and exhibit long-term elastomer life and sealing capability?
  • PAT in Perspective: Safe? Yes. Effective? Not So Much.
    Pharmacopoeia plans to list specific functionality related characteristics (FRCs) in its excipient monographs next spring. The tests will be non-mandatory. There may also be a General Chapter concerning FRCs addressing theses tests where they appear in monographs. My humble opinion
  • Minimize Dust Explosion Hazards
    are particularly important because they determine a powdered material's sensitivity to various ignition sources such as hot surfaces, electrical or frictional sparks. The lower the MIE and MIT values, the more dangerous the powder. Because pharmaceutical products and intermediates tend to be unique materials
  • Effects of Graphite Type, Purity and Concentration on Grease Performance (.pdf)
    from ASTM D2266 were augmented with graphs of coefficient of friction plotted as a function of time and optical micrographs of four-ball wear scars for each sample tested. Four-Ball Wear testing (D2266) shows that grease performance is a function of graphite type. There is very limited evidence
  • Surface Enhancements Eliminate ESD Damage During Operation of State-of-the-Art I.C. Handlers
    and performance of key Exatron handler components such as precision trackwork, main plates, extrusions, input & output mechanisms, rails and slides. All these metal surfaces are subjected to potentially severe friction from the constant action of plastic and ceramic I.C.s being run through testing cycles.
  • Characterization of Automotion Brake Thermal Conditions by the Use of Infrared Thermography
    , it affects the surface temperatures resulting from the small influence on the friction of the brake shoes. Keywords: vehicles, emission tests, brakes, infrared, thermography INTRODUCTION A close collaboration is sustained between different automotive companies established in Spain, such as SEAT-WOLKSWAGEN
  • Micro-Optical Sensors for Boundary Layer Flow Studies (.pdf)
    This manuscript describes optical MEMS (or MOEMS)-based microsensors for near wall boundary layer flow and particle field analysis. The sensors have been developed to measure a variety of parameters including flow velocity, surface speed, skin friction, and particle sizing. The surface mounted
  • Breakthrough in Brake Squeal Prediction Helps to Eliminate Noise Problems Early in Design Process
    Engineers have succeeded in recent years in reducing many types of automobile noise. However, friction-induced squeal in automotive brakes is an increasing source of customer. complaints. Currently, brake noise is one of the top warranty issues that automobile original. equipment manufacturers
  • Thermal Imaging of Medical Saw Blades and Guides
    Better Than New, LLC, has developed a surface treatment to reduce the friction and wear of orthopedic saw blades and guides. The medical saw blades were thermally imaged while sawing through fresh animal bone. An IR camera was used to measure the blade temperature as it exited the bone. The test
  • PROTECT YOUR INVESTMENT: Five factors to consider before making the switch to aftermarket oil
    . running at the right temperature? Does the friction. horsepower or bearing loss align with what was expected. for this compressor at this temperature and for this. application? This level of testing gives OEM manufacturers. the confidence to stand behind their oil, because they fully. understand how
  • Piezo Motors: Principle of Operation for Engineers
    nondestructive testing. Piezoelectric Motors. Because very high voltages correspond to only tiny changes in the width of the crystal, this crystal width can be manipulated with better-than-micrometer precision, making piezo crystals an important tool for positioning objects with extreme accuracy
  • Tin Vs. Bare
    simple, the real world practitioners have experienced different results than the lab testing would suggest. Our own testing has proven both types of copper can be right if you add in the missing variable...time. Fresh, new, bare copper conductor works great. Unfortunately, we have found
