This standard specifies the terms and definitions, test principles, test equipment, test samples, test environment, test procedures, data processing, measurement uncertainty and test report of the Fourier transform method for testing the infrared transmittance of infrared optical glass. This standard is applicable to the test of infrared transmittance of infrared optical glass with a wavelength not lower than 2.5 μm. Infrared optical materials such as crystals and ceramics can also be used as a reference.
