TABLE OF CONTENTS
MECHANICAL LEVEL PERFORMANCE
Mechanical protection index on a scale of 0-4 or 5, recital 5 being the highest and 0 the minimal or no protection.
A- Abrasion Resistance
Risk of abrasion during handling of objects with rough and abrasive surfaces such as bricks, concrete blocks, plates, etc.
B- blade cut resistance
Protection against cutting when metal surfaces such as plates and edged in construction, forging, sheet metal, etc. are handled Risks not covered cutting knives or chainsaws.
Tear resistance C-
Glove resistance to tear. The appropriate value depends on the conditions of the task.
Puncture resistance D-
Glove measures the resistance to penetration by sharp objects such as chips, pieces of wood, iron, etc. Trials of the EN 388 are not designed to protect against pricking by needles or fine tips. To do this, gloves in the market specifically designed for this use.

PERFORMANCE LEVEL THERMAL HEAT AND FIRE
Thermal protection index on a scale of 0-4 recital 4 being the highest and 0 the lowest.
The X instead of a number sign indicates that the glove is not designed to be used against the corresponding risk.
Burning behavior A- (0-4)
B- Contact heat (0-4)
C- Convective heat (0-4)
Radiant Heat D- (0-4)
E- Small splash molten mental (0-4)
F- Large masses of molten metal (0-4)

COLD level of thermal performance
Thermal protection index on a scale of 0 to 4.
Performance levels A and B is considered 4 0 maximum protection and minimal or absent protection.
In the performance level C, is considered one protected and unprotected 0
A- The level of thermal insulation against convective cold. (0,1, 2, 3 or 4)
B- The level of heat resistance, heat insulation contact. (0,1, 2, 3 or 4)
C- The level of resistance to penetration of water (0 or 1)

PERFORMANCE LEVEL OF CHEMICAL AND BACTERIOLOGICAL
The "A", "J" and "K" codes designated chemicals for which it has obtained the test of resistance to permeation.
UNE-EN 3741: 2004 includes a list of 12 chemical substances that have been assigned a letter from "A" to "L".
For a glove is considered chemical protection must pass the test of resistance to permeation, for at least three of the compounds of the list, regardless of all other compounds for which the manufacturer wishes to test their gloves.
