This article is about the development of angular classification methodology (vertical and horizontal) of theodolites and total stations. The methodology was based on Brazilian (NBR 13.133) and International (ISO 17.123-3) rules. In order to accomplish that objective, several steps were developed; initially the telescope of an optical theodolite was turned into a collimator. Its filters and illumination were also developed, as well as its support. After this step, the assembling of a laboratory and the performance of tests began. At horizontal angular classification, field tests were compared with laboratory tests. Data obtained were applied into an arithmetic spreadsheet that issues the classification of the equipment according to NBR 13.133. And at last, tests were performed with industrial collimators which were compared to previous results. In the vertical angular classification, data obtained from laboratory with assembled collimators were compared to data of industrial collimators. All data were evaluated with Global and Data Snooping statistical tests. Final results confirmed the efficiency of the developed methodology to create a laboratory of horizontal and vertical angular classification at the UFPR, as well as the satisfactory result of the assembled collimator on laboratory that presented low development cost.
