<\/figure>\n\n\n\nThis is the basic requirement for proving the FR characteristics of a given fabric. Only after approval in this test, the fabric can be submitted to the other tests of the standard, namely:<\/p>\n\n\n\n
\u2022 Method B: It must reach at least level B1.
\u2022 Method C: radiant heat. It must reach at least level C1.
\u2022 Method D: projection of molten aluminum. It must reach at least level D1.
\u2022 Method E: projection of molten iron. It must reach at least level E1
\u2022 Method F: heat by contact. It must reach at least level F1.<\/p>\n\n\n\n
Fabrics designed to protect against molten metal projection must meet the requirements of the test methods classified as D and \/ or E, that is, protect against aluminum and iron, respectively. Both tests are performed by projecting a limited amount of metal onto the fabric. It is subsequently evaluated whether there was damage (carbonization, puncture or ignition) in the material.<\/p>\n\n\n\n
As for protection against weld spatter, the fabric must be approved according to the ISO 11611 standard, which will measure the amount of spatter necessary for the fabric to have its temperature raised by 40 \u00b0 C. In this standard there are two classifications:<\/p>\n\n\n\n
\u2022 Class 1: More than 15 weld spatters.
\u2022 Class 2: More than 25 weld spatters.<\/p>","protected":false},"excerpt":{"rendered":"
