EN 407 Heat-related risks

Tested levels of glove performance in terms of the following risks:

Resistance to flammability (0 to 4)

Resistance to contact heat (0 to 4)

Resistance to convective heat (0 to 3)

Resistance to radiant heat (0 to 4)

Resistance to small splashes of molten metal (0 or 1)

Resistance to large splashes of molten metal (0 or 1)

0 means that during the test level 1 was not reached.

X means that the test was not performed or not possible.

EN 511 Cold-related risks

Tested levels of glove performance in terms of the following risks:

Climatic or industrial cold transmitted by convection (0 to 4).

Climatic or industrial cold transmitted by contact (0 to 4).

Impermeability to water (0 or 1).

If the glove shows this symbol, it has achieved a performance index for (from left to right) climatic cold or industrial cold transmitted by convection, climatic cold or industrial cold transmitted by contact, impermeability to water.

0 means that during the test level 1 was not reached.

X means that the test was not performed or not possible.

EN 388: 2016 Mechanical risks

Revision of EN 388: 2003 The EN 388 standard underwent revision in 2016. SHOWA gloves are in the process of being recertified by the notified bodies to conform to the revised standard. Currently reported ISO 13997 cut resistance values are indications until officially certified. In the meantime the existing certificates according to EN 388: 2003 remain valid.

a) ABRASION RESISTANCE (0-4) Number of cycles required to abrade a hole using abrasive paper in a circular sample of glove material under constant pressure and motion.

b) BLADE CUT RESISTANCE BY COUP TEST (0-5) Number of cycles required to cut a sample using a stainless steel circular blade under constant speed and low force of 5 newtons (approx. 510g). For materials that dull the blade, after a certain number of cycles without cut through, the ISO 13997 test is performed and becomes the reference cut resistance value.

c) TEAR RESISTANCE (0-4) Force required to propagate a tear in a rectangular sample of a glove with a starting incision, to a maximum force of 75N (approx. 7,6kg).

d) PUNCTURE RESISTANCE (0-4) Force required to puncture the sample with a standard size steel point at a constant speed of 10 cm/min.

e) BLADE CUT RESISTANCE BY ISO TEST (A-F) Force in newtons (N) required to cut through a sample using a rectangular blade in a specified cut test machine such as Tomodynamometer (TDM). This test is optional unless the blade in Coup test becomes dull, whereupon it becomes the reference for cut resistance. A letter value is assigned as follows:

f) IMPACT RESISTANCE (P) For protective gloves claiming impact resistance. Measures dissipation of force by the area of protection upon an impact of a domed anvil at an impact energy of 5 joules. Testing is carried out in accordance with the impact protection test for motorcycle protective gloves of EN 13594:2015 standard. A letter P is added on successful pass, while a fail remains unmarked.

Level X can also be applied for a f above, which means not tested .
