Proč Redline?
Redline představuje rychlý a snadný způsob jak porovnat všechny změny mezi aktuální platnou normou a předchozí verzí.
Díky redline se okamžitě dozvíte o:
Ušetřete si čas i starosti!
Díky Redline již nebudete muset ztrácet čas zjišťováním, co se v nové normě změnilo. Redline Vám ušetří čas a zaručí, že se o změnách v normě dozvíte.
Cena
Pokud si zvolíte možnost "Platná norma + Redline", pak dostanete oba dokumenty! A co je nejlepší, cena Platné normy + Redline je pouze o něco málo vyšší než cena samostatné 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.
