The differences between these two legislative acts are few. However, one difference in particular affects EN As EN does not provide for the assessment of oven gloves, the European Commission asked the European Committee for Standardization CEN to quickly revise the standard so that it would also cover household gloves that protect against thermal risks. Standardisation has considerably changed since Before, it was almost exclusively a European phenomenon EN standards for gloves.

EN is an international glove standard that consists of 6 independent performance tests designed to measure and define thermal work gloves. Work gloves designed for high-heat exposure must be tested using the vertical flame test to measure both after-burn time and after-glow time for EN certification. This test measures the ability of the material to extinguish itself after being ignited using 4 performance levels. This is achieved by placing sample material on pre-heated plates and recording the temperature rise at each level for at least 15 seconds.
When the Contact Heat performance level reaches 3 or 4, the Burning Behavior test must be performed and achieve at least a level 3, otherwise the maximum performance rating for Contact Heat will be reported as level 2. Thermal protection from convective heat is determined by measuring the rate of temperature rise inside the glove when put in contact with a controlled gas flame.
A level of performance in Convective Heat shall only be reported if a performance level 3 or 4 is obtained in the Burning Behavior test.
The Radiant Heat test ensures the glove materials can resist high-heat through the back of the hand for a designated time period. This test measures the back and palm in a closed chamber where the number of metal droplets is determined and the lowest mean number of 4 tests is recorded. Thermal Resistance to Large Quantities of Molten Metal testing is measured against PVC foil skin to simulate the inside of the glove, and molten metal is poured over the test sample.
The skin simulant is assessed after each test and should not show any smoothness to the grained surface. The Thermal test is considered failed if steel droplets stick to the glove or if the glove ignites or is punctured.
