Teragren's proprietary manufacturing adhesive emits less formaldehyde than allowed by U.S. OSHA, European E0, CARB Phase 1 and CARB Phase 2, and Japanese JIS/JAS (F☆☆☆☆) emission standards.
Periodically Teragren tests its products by utilizing an independent testing laboratory in the United States. The test used to determine formaldehyde off-gassing is the "Large Chamber Test for Formaldehyde Emissions" and is run in accordance with ASTM E1333. The results of these tests and their comparison to international standards are listed below.
