Glove Juba - 21738 JUBA

Name: 21738
Brand: Juba

Fireproof split leather mitten, fully lined.

Normative

Requirements and test methods for welder's gloves. It classifies them into two types:

Type A general welder gloves.
Type B tact welder gloves. High desterity TIG welding case.

Warnings

At the moment there is no test method to determine the penetration of UV radiation through the materials from which the glove is made.
When gloves are intended for arc welding: These gloves do not provide protection against electric shock caused by faulty equipment or live work, and electrical resistance is reduced if the gloves are damp, dirty, or sweat-wet, which could increase the risk.

EN388:2016 Protective gloves against mechanical risks.
The EN388: 2003 standard is renamed EN388: 2016, the year of its revision. The reason for the modification is given by the discrepancies in the results between laboratories in the knife cut test, COUP TEST. Materials with high levels of cut produce a dulling effect on the circular blades, which undermines the result.

The new regulation was published in November 2016 and the previous one is from the year 2003. During these 13 years, there has been a great innovation in the materials for the manufacture of cutting gloves, they have forced to introduce changes in the tests to be able to measure with more rigorous levels of protection.

Ratified by the Spanish Standardisation Association in June 2020.

Main changes:

Extension of the scope of the standard to domestic use: oven mitts/gloves.
Gloves that reach a level 3 or 4 of any thermal property must reach at least a level 3 in flame propagation. Otherwise, the maximum level that may be reached in the relevant thermal property shall be level 2.
Propagation limited to flame: prohibition of hole formation. Reduction of maximum post-combustion time for level 1. Change in ignition timing.
Heat by contact. Obligation to test any material coming in contact with heat.
Tear resistance. This trial is included.
Convective heat. The test is performed without reinforcement.
New pictogram, for gloves without flame protection.
A minimum length is introduced when resistance against small molten metal splashes is present.
After heat resistance tests, the samples must not suffer signs of melting or holes.
