Standardi Torque Constringendi Vinctores GIS secundum Materialem et Magnitudinem
GIS (Apparatus Electricus Isolatus Gas) continet multas iuncturas coniunctas per clavos et viscos, et torque strictus variat secundum materiam clavi, magnitudinem, et applicationem. Valores torquorum strictorum recommendati sunt subiecti pro reference:
