ACM is an acronym used as an abbreviation for Asbestos Containing Material. It is used commonly within the asbestos removal and management industry.
Asbestos Containing Material may be used to refer to any type of asbestos containing material including (but not limited to) Asbestos Insulating Board (AIB), asbestos flock and asbestos cement. It may also refer to any other material suspected to contain asbestos.
‘Suspected ACM’ is another term used and related to a material suspected to contain asbestos, but which hasn’t been tested to confirm if it contains asbestos, but which would appear to be material known to have been manufactured containing asbestos.
