E0 is the average formaldehyde emission of 0.5 mg/l, which is the most stringent international standard for formaldehyde emission of composite wood flooring. \x0d\E 1 means that formaldehyde emission reaches 1.5MG/L ... which is the mandatory standard for formaldehyde emission of composite wood flooring in China. \ \x0d\ \x0d\E 1+0 formaldehyde emission is a safety standard, and E0 stands for harmless standard. Compared with the two, safety is relative, harmlessness is absolute, and harmlessness brings people a fresher and healthier environment than safety! It can be seen that E0, as the highest limit of formaldehyde emission from composite wood flooring, can be compared with the hygiene and safety standards of food, drinking water and other related products.
