E1, E0 & ENF — emission, not moistureE1、E0 与 ENF——释放等级，而非防潮

What the grades mean这些等级的含义

E1, E0 and ENF are formaldehyde-emission classes — how little the board off-gasses into your indoor air. The scale runs from low (E1) to lower (E0) to the cleanest class (ENF).E1、E0 与 ENF 是甲醛释放等级——衡量板材向室内空气释放气体的多少。等级从低（E1）到更低（E0），再到最洁净的等级（ENF）。

• E1 — a recognised low-emission grade.E1——公认的低释放等级。
• E0 — cleaner indoor air than E1.E0——室内空气比 E1 更洁净。
• ENF — the lowest-emission class.ENF——释放等级最低的类别。

Why it is not a moisture rating为何它不是防潮评级

A board can be ENF (very clean air) and still swell in a wet zone, because emission and moisture resistance are unrelated properties. Choosing ENF improves the air in the room; it does nothing for a leaking sink base.一块板材可以是 ENF（空气非常洁净），却仍会在湿区膨胀，因为释放与防潮是互不相关的两种特性。选择 ENF 能改善房间空气；但对漏水的水槽底柜毫无帮助。

What we don’t say我们绝不会说的话

We never describe wood as ‘zero formaldehyde’ — ENF is the lowest-emission grade, not formaldehyde-free. And we never call wood ‘waterproof’. Honest specs build trust.我们绝不把木材描述为“零甲醛”——ENF 是释放等级最低的等级，并非无甲醛。我们也绝不把木材称为“防水”。诚实的规格才能建立信任。

How to use it如何运用这一点

Pick the zone-correct construction first (board/plywood vs aluminium), then choose the emission grade you want for indoor air. ENF is available as an upgrade across the board family.先选对与区域相匹配的结构（板材/胶合板还是铝合金），再为室内空气选择你想要的释放等级。整个板材系列均可升级至 ENF。
