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 minimum requirements for scales, balances, reference masses, and glass graduates used in the physical testing of hydraulic cements. Requirements for analytical reference masses and balances are not included in this specification. Reference masses for use in the methods of physical testing of hydraulic cement and related and similar materials shall conform at least to the requirements of Class 6 reference masses given in this specification. The maintenance tolerances given in this specification for Class 6 reference masses are to be considered acceptance tolerances for purposes of this specification and the maintenance tolerances twice these values. Requirements for scales, balances, and glass graduates shall conform at least to the requirements for capacity, precision and accuracy, readability, and sensitivity.
