22.12 中提到的self-hardening resins究竟是什么胶水啊？问过不少人，但都说不清楚。主要是搞不清楚我们常用的胶水当中有哪些是self-hardening resins。TUV他们可以接受哪些？
相关条款如下：
22.12 Handles, knobs, grips, levers and similar parts shall be fixed in a reliable manner so
that they will not work loose in normal use if loosening could result in a hazard. If these parts
are used to indicate the position of switches or similar components, it shall not be possible to fix
them incorrectly if this could result in a hazard.
Compliance is checked by inspection, by manual test and by trying to remove the part by
applying an axial force of
– 15 N, if an axial pull is unlikely to be applied in normal use;
– 30 N, if an axial pull is likely to be applied in normal use.
The force is applied for 1 min.
NOTE Sealing compound and similar materials, other than self-hardening resins, are not considered to be
adequate to prevent loosening.. |
