  • Home Fire Safety Using Thermal Imagers
    homes reducing money out of our pockets. But did you know that thermal imagers can also help us to detect dangerous fire hazards before they result in damage and injury, saving money, and potentially lives? When electric circuits have an increased resistance and begin building up excess heat
  • Testing for Flame Resistance of Electrical Cables
    The National Fire Protection Agency (NFPA) publishes flame-resistance standards through its published National Electrical Code (NEC). Other agencies, such as UL and CSA also publish standards and also define certain tests for determining flame resistance (or lack thereof). Flame resistance
  • Differences in Water Glycol Hydraulic Fluids Can Have Serious Effects
    Fire-resistance has made water-glycol-based hydraulic fluids (WGHFs) the preferred choice for hydraulic applications in the primary metals industries, including aluminum die casting. Their low flammability and relatively low cost have also made these products attractive for general hydraulic use.
  • Thermal Response Characteristics of Marine Grade Radome Composites Designed for use on Spruance Class Naval Destroyers
    Survivability of marine grade composite structures exposed to fire is of greatest concern due to a number of issues including: flammability, fire growth, fire resistance, fire protection, and structural integrity. A warship can expect to encounter intense fire exposure during battle conditions
  • Complex stainless weldment used in marine, pharmaceutical and semiconductor application. Part needs high corrosion resistance.
    The customer needed parts to withstand a variety. of environments, such as salt air, harsh chemicals, etc. without. rusting or discoloring. The parts are used on fire fighting equipment, and in. pharmaceutical laboratories where harsh chemical wash downs are required. The components are also used
  • Powering Safety Systems - Giving Yourself Significant Power "Headroom" (.pdf)
    that impact voltage reaching the fire or gas detector, any one of which may cause an unwanted shutdown or damage to the instrument. The most fundamental factor to consider is wire resistance between the power supply and the device but there many other factors.
  • Detecting Circulating Currents and Hot Spots in Normally Non-current Carrying Conductors and Structural Members
    or even fire. Conducted or radiated heat from nearby hidden sources can also cause hotspots in unexpected locations. This heat is easily detected with infrared scanning. Through its Comprehensive Services Program (CSP), the Tennessee Valley Authority contracts with its distributors of electric power
  • Designs that won't go up in smoke
    , a sample of a cellular silicone called Bisco selfextinguishes, passing the flame test while another silicone product curls and burns. Bodycote Materials Testing Canada Inc., Mississauga, Ont., performs full-scale fire tests on upholstered furniture in accordance to California Technical Bulletin 133
  • Using Switching Power Supplies with Diode Isolated Capacitor Banks
    In many applications it is desirable to charge multiple capacitor banks with one or more power supplies ganged together. In some cases the banks must be isolated with diodes to allow the banks to fire at different times. Several items should be added to this circuit for proper operation. Resistors
  • Polyimide
    Available both as thermoplastic and thermoset resins, polyimides (Pls) are a family of some of the most heat and fire-resistant polymers known. Moldings and laminates are generally based on thermoset resins, although some are made from thermoplastic grades. Unlike most plastics, Pls are available
