Inherently flame-retardant fabrics are certified in the United Kingdom by various British Standards. Fire-retardant fabrics sold in the UK for use as curtains must abide by BS 5867 Part 2 B & C, a British Standard. Other relevant UK standards include BS 5815-1 2005, BS 7175, Crib 5, IMO A563 and NFPA 701.
The law requires fabric to pass a smouldering test. The test exposes fabrics and foams to burning cigarettes for 45 minutes. The test exposes fabrics and foams to burning cigarettes for 45 minutes. The ignition and char level are measured, with the goal being that the cigarette extinguishes without the fabric or foam igniting.
When it became apparent that the risk-benefit ratio of this approach was unfavorable and industry had used falsified documentation (i.e. see David Heimbach) for the use of flame retardants, California modified TB 117 to require that fabric covering upholstered furniture meet a smolder test replacing the open flame test.

The U.S. Flammable Fabrics Act is an act that was passed in 1953 to regulate the manufacture of highly flammable clothing. [1] [2] It was enacted after years of rayon viscose fabrics being proven to be the primary cause of quick starting, high temperature fires as well as having the secondary effect of causing illnesses in factory workers.

Generally the ranking of the various common flame retardant tests worldwide for furniture and soft furnishings would indicate that the California test Cal TB117 - 2013 test is the most straightforward to pass, there is increasing difficulty in passing Cal TB117 -1975 followed by the British test BS 5852 and followed by Cal TB133.

Incorporating flame-resistant additives into polymers became a common and relatively cheap way to reduce the flammability of polymers, [6] while synthesizing intrinsically fire-resistant polymers has remained a more expensive alternative, although the properties of these polymers are usually more efficient at deterring combustion.
FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The ...
The test method evaluates the thermal resistance and water vapor permeability of fabrics, which bear on the garment's comfort. [25] [26] ISO 11092:2014 (the test for physiological effects — Test for measuring thermal resistance and water-vapor resistance) [27] ASTM F1868 (test for measuring thermal and evaporative resistance) [28]
