Prečo Redline?
Redline predstavuje rýchly a jednoduchý spôsob ako porovnať všetky zmeny medzi aktuálne platnou normou a predchádzajúcou verziou.
Vďaka redline sa okamžite dozviete o:
Ušetrite si čas aj starosti!
Vďaka Redline už nebudete musieť strácať čas zisťovaním, čo sa v novej norme zmenilo. Redline Vám ušetrí čas a zaručí, že sa o zmenách v norme dozviete.
Cena
Ak si zvolíte možnosť "Platná norma + Redline", potom dostanete oba dokumenty! A čo je najlepšie, cena Platné normy + Redline je len o niečo málo vyššia ako cena samostatnej platné normy.

This specification covers the requirements to which flat-cast, amorphous, semi-processed, iron-base magnetic core alloys must conform. These alloys shall be produced by a rapid-quenching, direct-casting process, resulting in metals with noncrystalline structure. The alloys shall be made to meet specified maximum core-loss values and shall be intended primarily for commercial power frequency applications. Desirable core-loss and permeability characteristics shall be developed by further heat treatment in a magnetic field. Amorphous magnetic core alloys are normally composed of iron with small amounts of alloying elements such as boron and silicon. There are no specific chemical requirements in this specification. Material produced to this specification shall conform to the required physical and mechanical properties such as density, ductility, thermal expansion, thermal conductivity, volume resistivity, lamination factor, surface, edge, and pinholes. The alloy shall also conform to the magnetic property requirements such as DC induction, DC coercive field strength, DC residual induction, core loss, and specific exciting power.
