Fire-Proof Cloth
TOMBO™ No. 8300
FIRE PROOF CLOTH
Shipyards and construction sites are constantly exposed to the risk of fires due to spatter and slag produced during welding and cutting. There may also be cases where vital equipment such as computers could be damaged. Our Fire-Proof Cloth is a dedicated spark-protection cloth developed to withstand such severe conditions.

Comparison with carbon-based cloth
Specimen

FIRE PROOF CLOTH SW cloth surface (Nichias product)
FIRE PROOF CLOTH SW coating surface (Nichias product)
A typically used carbon-based cloth
Test conditions and test method
JIS A 1323 Class A equivalent
The four test specimen types were used to assess the flame retardancy of sparks generated when a 9mm-thick steel plate for spark generation was cut.
Judgment criteria
No through holes that are harmful in terms of ignition and fireproofing.
Test results
No through holes that are harmful in terms of ignition and fireproofing were made in either test specimen during the test (about 48 seconds long).
However, smoke was observed after the “typically used carbon-based cloth” was cut on its own.
A video of the test is below.
