- Refer to the testing report
Focus on these few items: - Testing method: The 1m ³ climate chamber method must be written. Other methods (dryer method, perforation method) have low reference value and cannot be used to determine ENF/E0.
- Sample name: It should be consistent with the floor model and batch you want to buy.
- Formaldehyde emission value: Refer to the ENF/E0/E1 limit above.
- Testing institution: Possess CMA qualification (with CMA seal on the report).
Pit: The merchant took a sample report for inspection, but the actual shipment was another batch of boards; The contract must specify that the shipped boards are from the same batch and can be re inspected. - Check the product packaging/certificate of conformity
The formal floor packaging and product certification will indicate the formaldehyde emission level (ENF/E0/E1) and the implementation standard number.
However, packaging labeling can only serve as a reference and cannot replace CMA testing reports, as there may be false labeling. - Check the cutting surface of the board (auxiliary, cannot be graded)
-Reinforced composite: The substrate is delicate and compact, without any pungent or sour taste; Poor quality density board is loose and has a strong odor.
-Solid wood composite: clear layering of cut surfaces; Poor quality multi-layer with a large amount of miscellaneous wood and glue, with a noticeable irritating odor when close to it.
Key misconception: Smelling cannot determine formaldehyde level!
Formaldehyde itself has a weak irritant odor, and many of the pungent odors smelled are from paints and additives, not formaldehyde; Odorless ≠ Low formaldehyde. - Recheckable (Rights Protection)
If there are any doubts after receiving the goods, you can take samples and send them to CMA laboratory by yourself. The contract should be written in advance: if the re inspection does not meet the agreed level, the merchant shall bear the testing fee and return compensation.
