热致变色是由温度变化引起的透射率、反射率或吸收率的可逆变化。光致变色是光辐射引起的相应效应。这些影响可能发生在使用反射率标准时，因为当受到许多测量仪器使用的多色辐射时，它们可能会经历相当大的温度上升。本文介绍了十二种陶瓷色标的任何热致变色（和光致变色）性质的调查。结果表明，热致变色效应仅在约一半的标准中在很小的程度上是显著的，而在其余的标准中根本不显著，同时没有任何光致变色的证据。
Thermochromism is a reversible change oftransmittance, reflectance, or absorptance induced by a change of temperature. Photochromism is the corresponding effect induced by optical radiation. These effects can occur in the use of reflectance standards, as they may undergo a considerable temperature rise when subjected to the polychromatic irradiation used by many measuring instruments. An investigation of any thermochromic (and photochromic) properties of the twelve Ceramic Colour Standards is described. It is shown that thermochromic effects are only significant to a very small extent in about half of the standards and not at all in the remainder, while there is no evidence of any photochromism.
