Results of joint investigations of the State Primary Standard of the unit of length, the meter (GET 2–2010), State Primary Special Standard of the unit of length (GET 199–2018), and State Primary Special Standard of the unit of length in the field of measurements of the geometric parameters of surfaces of complex form (GET 192–2017) are presented. The objective of the study is to confirm the metrological characteristics of the standards. As a result of the investigations, assurance of the uniformity of measurements of the unit of length in the Russian Federation is confirmed.
