17-0501 v3.1/Phenol Formaldehyde Polymers in Foam Board Insulation

ANSWER:

(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 containing phenol formaldehyde polymers may be used if, as specified in the California Air Resources Board (CARB) Regulation.

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).

This exception does not apply to polymeric materials with urea-formaldehyde or urea-melamine or mixtures of these materials with phenol formaldehyde. The team must provide technical documents demonstrating compliance.
