17-0501 v3.1/Phenol Formaldehyde Polymers in Foam Board Insulation
(v2.1) I11-E24 Phenol Formaldehyde Polymers in Foam Board Insulation + (v3.1) I10-E23 Phenol Formaldehyde Polymers in Foam Board Insulation
Foam board insulations contain
- the phenol formaldehyde polymer in the insulation contains acceptable levels of free/residual formaldehyde, and
- the phenolic foam boards' bonds are between formaldehyde and phenol, resorcinol, cresols, or a mixture thereof.
To demonstrate compliant levels of free/residual formaldehyde, the manufacturer or supplier must:
- conduct testing of the polymer in accordance with ISO 11402 (Formaldehyde content) or EN 717 (Formaldehyde emissions) or an equivalent standard, and
- document that test results were below the CARB formaldehyde limits (content or emissions).
