ISO 18314-1:2015规定了确定漆膜颜色坐标的方法。该方法仅适用于在正常视力下检查时，呈现出单一颜色（即单色）的漆膜。不完全隐藏不透明基材的漆膜代表不透明系统，可以使用ISO 18314本部分中的程序进行测量。 发光漆膜、透明漆膜和半透明漆膜（例如显示器或灯玻璃）、反光漆膜（例如交通标志）和金属漆膜不在ISO 18314本部分的范围内。

ISO 18314-1:2015 specifies the method for determining the colour coordinates of a paint film. This method is only applicable to paint films that appear to be uniformly of one colour, i.e. monochromatic, when examined with normal vision. Paint films that do not completely hide a non-transparent substrate represent an opaque system and can be measured by using the procedure in this part of ISO 18314. Luminescent paint films, transparent paint films, and translucent paint films (for example for display or lamp glass), retroreflecting paint films (for example for traffic signs), and metallic paint films are outside the scope of this part of ISO 18314.
