Can a manufacturer use a small emissions chamber as a routine quality control test method?
Yes, but a small chamber needs to be correlated to the primary or secondary test method. Manufacturers may deem a small emissions chamber as equivalent to a primary method. Small chambers deemed equivalent cannot be used by manufacturers for verification quarterly tests for certification purposes. Quarterly tests must be conducted by the respective third party certifier of the given manufacturing mill. 35. Will CARB accept E1 boards as meeting the Phase 1 standard? No. While CARB’s Phase 1 standards are comparable to E1 emission levels for particleboard and medium density fiberboard, differences in the test methods and the amount of in-plant quality assurance testing done in Europe varies considerably from CARB’s requirements. Even if boards meet the E1 standard, the mills producing those boards would need to be certified by an independent organization and have test data to show that it also meets the CARB Phase 1 standard using the primary or secondary test method, if they are offered
