ASTM A193 Scope

Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications.  The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.

Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

    The Intelligent Key system allows you to conveniently lock, unlock and start the vehicle, all without removing the Intelligent Key from your pocket or purse.

    Up to four Intelligent Keys can be used with one vehicle, provided they are registered with a Nissan dealer prior to using the system.

    To unlock a door from outside the vehicle, have the Intelligent Key with you and then push THIS request switch on the door handle. That door will unlock. Push the switch again within one minute to unlock all doors.

    To lock your vehicle, push any door handle’s request switch once after all doors have been closed.

    These lock and unlock functions are operational when the Intelligent Key is within about 2 ½ feet of the corresponding request switch.

    The Intelligent Key has remote keyless entry functions that can operate within approximately 33 feet of the vehicle.

    To lock your vehicle this way, press the LOCK button.

    The hazard lights flash twice and the horn beeps once to let you know that the doors are locked.

    Press the UNLOCK button to unlock the driver’s door. Press again within five seconds to unlock all doors.
    Your Intelligent Key can be used to adjust the hazard indicator and horn beep features.

    To deactivate the horn beep feature when using the remote keyless entry function to lock or unlock the vehicle, press and hold the LOCK and UNLOCK buttons simultaneously for more than 2 seconds. The hazard indicator will flash three times. To reactivate the feature, press and hold the buttons again for more than
    2 seconds. The hazard indicator will flash once and the horn will beep once. Your Intelligent Key is equipped with a PANIC ALARM button.
    If you are near your vehicle and feel threatened, press it for more than one half of a second.

    The panic alarm will sound for a period of time or until any button on the key fob is pressed.

    Once inside the vehicle, you can lock and unlock all doors by pushing the driver’s or front passenger’s power door lock switch. Individual doors can be manually locked or unlocked using the inside lock knobs.

    If you exit the vehicle with the Intelligent Key left inside, all doors will unlock and a warning chime will sound as soon as you close the door.

    In the rare instance when your Intelligent Key battery is discharged, you can still lock or unlock the vehicle. You’ll find a mechanical key concealed on the back of the Intelligent Key. To remove it, release the lock knob and slide the mechanical key out. You can then insert it into the key cylinder on the driver’s door and turn to lock or unlock the vehicle.

    The Intelligent Key contains sensitive electrical components. Please avoid these circumstances that could affect its operation:
    ● Avoid dropping or striking it against another object,
    ● Keep it away from water,
    ● Keep it away from equipment with magnetic fields, including computers, cell phones, TVs and audio accessories, and
    ● Avoid using a key chain that contains a magnet.

    Please see your Owner’s Manual for important safety information, system limitations and additional operating information.
