In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
Operating temperature. An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum ...
The heat distortion temperature is determined by the following test procedure outlined in ASTM D648. The test specimen is loaded in three-point bending in the edgewise direction. The outer fiber stress used for testing is either 0.455 MPa or 1.82 MPa, and the temperature is increased at 2 °C/min until the specimen deflects 0.25 mm.
Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine ( T3) and thyroxine ( T4 ). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production ...
Accelerated life testing is the process of testing a product by subjecting it to conditions ( stress, strain, temperatures, voltage, vibration rate, pressure etc.) in excess of its normal service parameters in an effort to uncover faults and potential modes of failure in a short amount of time. [1] [2] By analyzing the product's response to ...
Service 02 accepts the same PIDs as service 01, with the same meaning, but information given is from when the freeze frame was created. Note that PID $02 is used to obtain the DTC that triggered the freeze frame. A person has to send the frame number in the data section of the message. Service 03 - Show stored Diagnostic Trouble Codes (DTCs)
Network interface device. In telecommunications, a network interface device ( NID; also known by several other names) is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring. Outdoor telephone NIDs also provide the subscriber with access to the station wiring and serve as a convenient ...
2024 aluminium alloy is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring high strength-to-weight ratio, as well as good fatigue resistance. It is weldable only through friction welding, and has average machinability. Due to poor corrosion resistance, it is often clad with aluminium or Al-1Zn ...
