Source for Test Lab to measure the appearance (specular, DOI and diffuse reflectance) of mirrors and mirror-like surfaces

The test method most applicable for specular gloss and DOI of mirrors is:

 ASTM E430 Standard Test Methods for Measurement of Gloss of High-Gloss Surfaces by Goniophotometry which describes the methodology used in the development of the legacy HunterLab Dorigon meter.

A company that sells a Dorigon replacement unit which is primarily a QA instrument is: 

Tricor Systems Inc.

 HunterLab does perform mirror testing and finding an optical testing lab for mirrors is not so easy but here are some possibilities.
