EN ISO 21420 is the standard that defines the general requirements that any glove or other type of equipment for hand and / or arm protection must meet.
This standard should always be used in combination with others.
It does not serve by itself to certify a glove.
The standard basically defines the performance, needs and test methods to be applied for:
BASIC DESIGN
SAFETY
CLEANING
ANTI-STATIC PROPERTIES
SIZES
DEXTERITY
COMFORT AND BREATH
MARKED

EN 511 is the standard that defines the performance levels for protective gloves against cold down to -50ºC, whether it is a risk associated with weather conditions or an industrial activity.

Los guante certificados para protección frente al frío deben adjuntar la correspondiente información para el usuario e incorporar el pertinente «marcado», como el indicado en los siguientes ejemplos.
