In previous years, this committee reported on the need for a US National Laser damage standard, addressing the needs of domestic industry. [1] Last year, a process was reported that connected the measurement of the active defect density in a small area, a, with the likely density of such defects over a larger area, A. This was presented as the basis of a Type 1, go/no-go test. The main issue as reported last year is that the proper flow of a standard is to start with the required properties of the larger area and design a robust test. The process presented in 2017 [2] is hard to implement in a way convenient for the non-expert user, which is nearly all. The main thrust of the work in 2018, is developing and evaluating options for implementing a useful workable standard.
