Verified locator: NIST Monograph 180, 1995; inspected corrected handbook. Preface names Ted Doiron and John Beers; official NIST publication record identifies Theodore D. Doiron and John S. Beers. §§2.2.2 and 6.1 define length using a wrung auxiliary plane and the wringing-layer convention; §5.3 mechanical comparison, §5.4.3.1 Eq. 5.8 thermal correction, §6.2 interferometers. Publication record: www.nist.gov/publications/gage-block-handbook .

Preface, printed p. iii (PDF p. 1), attributes the single-wavelength interferometry discussion to John Beers and the measurement-assurance program changes represented in Chapter 4 to author TD. The handbook preface uses Ted Doiron; the official NIST record for this same publication gives Theodore D. Doiron. The source title retains its published Ted spelling.

Additional wringing locators: Appendix B, Gauge Block Wringing, printed pp. 138–139, explains why atmospheric pressure alone is inadequate, describes fluid-dependent adhesion and time-varying contact layers, and discusses the defined-length convention. Section 3.2.1 describes inspecting a block wrung to a transparent optical flat for uniform contact appearance. Primary corrected handbook: www.nist.gov/document/mono180pdf .

Additional uncertainty/design locators: §4.4.3, Calculating the total uncertainty, separates information from the interferometric master history and comparison-process variability; §5.6.1 describes drift-eliminating observation designs. These support retaining a shared reference contribution and using an explicit observation-order model. www.nist.gov/document/mono180pdf .
