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 establishes the requirements for sheets and strips of various thicknesses produced from copper (Copper UNS No. C1000), copper-iron alloy (Copper Alloy UNS No. C19400), copper-zinc alloy that is commercial bronze (Copper Alloy UNS No. C22000), copper-zinc alloy that is red brass (Copper Alloy UNS No. C23000), copper-zinc-iron-cobalt alloy (Copper Alloy UNS No. C66400), copper-zinc-iron alloy (Copper Alloy UNS No. C66410), copper-zinc-iron-tin alloy (Copper Alloy UNS No. C66430), cupro-20% nickel (Copper Alloy UNS No. C71000), copper-clad bronze, copper-clad stainless steel, and copper-clad alloy steel. These materials are intended for use as electrostatic or electromagnetic shielding for insulated power, control, instrumentation, and communication cables. Cladding metals may be bonded to the specified base metal by any method that will produce products that will conform to the properties and characteristics prescribed herein. Materials shall be furnished specific to individual metals in the following tempers: H00 (cold-rolled, 1/8 hard), H01 (cold-rolled, 1/4 hard), H02 (cold-rolled, 1/2 hard); O61 (annealed), O81 (annealed, 1/4 hard), O50 (light annealed), O61 (annealed, soft), OS035, and OS015. Specimens shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, thickness, width, straightness, and cladding ratio), mechanical (tensile strength, and Rockwell hardness), electrical (mass resistivity, and conductivity), chemical composition, and grain size requirements.
