This method of test is applicable to slab stock phenol-formaldehyde foams for use in thermal insulation. It provides a means of distinguishing between punking and non-punking foams.
The test method described in this standard is primarily for the purposes of monitoring the consistency of production of phenol-formaldehyde foams. Its use gives an indication of the punking or non-punking behaviour of the material. In no circumstances should the test results thus obtained be considered as an overall indication of the potential fire hazard presented by the foam under actual conditions of use.
