Classification of thermoplastic wood adhesives for non-structural applications in the durability class according to EN 204:2017 is significantly influenced by the water temperature used during the test. When using dispersion with durability class D3 and D4 the bonding strength will decrease as the temperature rises. The temperature selected within the water temperature range specified in the standard can reduce the strength value by nearly a third, which can modify the classification regarding the corresponding durability class. Inappropriate classification is misleading the users which can cause their application on an inadequate field. Therefore the modification of standard in this field is recommended.

根据EN 204：2017，用于非结构性热塑性木材胶粘剂的耐用性等级受测试过程中使用的水温影响很大。当使用耐久性等级D3和D4的分散体时，粘合强度会随着温度的升高而降低。在标准规定的水温范围内选择的温度可使强度值降低近三分之一，这可以修改有关相应耐久性等级的分类。分类不当会误导用户，可能导致他们在不适当的领域进行申请。因此，建议在此领域中修改标准。
