Impact are able to undertake a wide range of fire testing to a number of standards to determine the flammability of your product.  A list of the most regular standards are listed below, but our expert team are able to advise on bespoke setups to replicate the real world application and performance of your product.

Impact were recently featured on the BBC with a segment on fire testing of external wall claddings similar to those used at Grenfell tower.

Horizontal Burning TestHBPlastic materials used to make enclosures for portable, attended, intermittent-duty, household-use appliance (i.e., hair dryers) or for decorative parts.
20mm Vertical Burning TestV-0, V-1 or V-2Plastic materials used to make portable, unattended, intermittent-duty, household-use appliances (i.e., coffee makers).
125mm Vertical Burning Test5VA or 5VBPlastic materials to be used in structural parts, enclosures and insulators in consumer electronic products. This test is the most intense test in UL94.
Thin Material Vertical Burning TestVTM-0,VTM-1 or VTM-2Plastic materials to be used as very thin films, generally not capable of supporting themselves in a horizontal position. These are usually assigned to substrates on flexible printed circuit boards.
Horizontal Burning Foamed Material TestHBF, HF-1 or HF-2Plastic materials for low-density foam materials commonly used in fabricating speaker grills and sound-deadening material.
ISO EN 11925-2
ASTM D635HBPolymeric materials used for parts in devices and appliances.
ASTM D3801V-0, V-1 or V-2Polymeric materials used for parts in devices and appliances. Cannot be used to classify materials used in building construction or finishing.
ASTM D50485VA or 5VBPolymeric materials used for parts in devices and appliances. Cannot be used to classify materials used in building construction or finishing.
Can be used to classify non-metallic materials if found appropriate.
ASTM D4804VTM-0,VTM-1 or VTM-2Plastic materials to be used as very thin films, generally not capable of supporting themselves in a horizontal position. These are usually assigned to substrates on flexible printed circuit boards.
ASTM D4986HBF, HF-1 or HF-2Low density foam materials.
UN Test N.1 Division 4.1Non Combustible, PGII, PGIIITest method for readily combustible solids to determine UN packaging group
BS EN 60695-11-10
IEC 60695-11-10 method A
HB, HB40, HB75Polymeric materials used for parts in devices and appliances. Test method used as a means of comparing the rate of burning, extent/time of burning, material selection and quality control of polymeric materials.
BS EN 60695-11-10
IEC 60695-11-10 method B
V-0, V-1 or V-2Polymeric materials used for parts in devices and appliances. Used for material selection and quality assurance. Cannot be used to classify materials used in building construction or finishing.
BS EN 60695-11-20
IEC 60695-11-20
5VA or 5VBPolymeric materials used for parts in devices and appliances. Used for material selection and quality assurance. Cannot be used to classify materials used in building construction or finishing.
Can be used to classify non-metallic materials if found appropriate.
ISO 9773 VTM-0,VTM-1 or VTM-2Plastic materials to be used as very thin films, generally not capable of supporting themselves in a horizontal position. These are usually assigned to substrates on flexible printed circuit boards.
ISO 9772HBF, HF-1 or HF-2Means of comparing the burning characteristics of foamed materials of like thickness density, cell size, skin irregularities and the effect of falling particles. It is useful for quality control, specification acceptance and research and development.
