Annotation of standard text ČSN EN 379+A1 (832431):

A1

Tato evropská norma určuje požadavky na filtry pro svařování, které při zapálení svařovacího oblouku automaticky spínají jejich světelný činitel prostupu na předem stanovenou hodnotu (filtr pro svařování se spínaným stupněm ochrany). Norma určuje rovněž požadavky na automatické filtry pro svařování, kde je hodnota světelného činitele prostupu stanovena automaticky v závislosti na intenzitě osvětlení generované svařovacím obloukem (filtry pro svařování s automatickým nastavením čísla ochrany).

Tyto filtry se používají v prostředcích k ochraně očí pro svářeče, nebo jsou součástí nějakého zařízení.

Požadavky na filtry pro svařování bez spínání světelného činitele prostupu jsou uvedeny v EN 169.
