This part of ISO 8322 specifies test procedures to be adopted when determining and assessing the accuracy in use of electronic distance-measuring (EDM) equipment on building construction, for distances up to 150 m.
The procedure applies to those types of EDM instruments used for surveying, control and compliance measurements and also when collecting accuracy data.
Annex A gives examples of the determination of systematic errors. Annex B gives the unit lengths of various EDM instruments.
