本规范涵盖了金属表面镀金的要求和镀层的性能。该工艺通常用于被动热控制应用，其中要求太阳辐射的高反射率和低吸收率，但使用不限于此类应用。

This specification covers the requirements for gold deposited on metal surfaces and the properties of the deposit.This process has been used typically for passive thermal control applications where high reflectance and low absorptance of solar radiation are required, but usage is not limited to such applications.
