Abstract: FIELD: measurement equipment. 
     SUBSTANCE: invention relates to the field of mechanical means of measurement, namely, to accessories for measurement of certain parameters of parts (length, width, thickness, etc.), specifically - to sets of gauge rods, and may be used in different areas of machine building, for instance, in production of tools, in assembling for measurement of gaps, in tuning of pointer-type measuring instruments, etc. In the universal set of gauge rods, comprising five groups of elements, dimensions of all elements of the set are subject to dependences (1)          A     1   −   m       =     A     n   −     (     m   −   1     )         +     δ       (     m   −   1     )             и         A     n   m   −   m       =     A     1   −   m       +     (       n   m     −   1     )       δ   m     ,                                                                                                                                                                                                                                                                         (   1   )           
, where A 1-m  is size of the first element of the group with the number "m"; A n-(m-1)  and δ (m-1)  is size of the last element and pitch of sizes of the group with the number "m-1"; A nm-m , n m  and δ m  - size of the last element, the number of elements and pitch of sizes of the group with the number "m". Number of elements in groups is subject to dependence (2)          n   1     =     (       K   1       δ   1     −     A     11         )     /     δ   1     +   1       и         n   m     =     [       K   m       δ   m     −     (       K     (   m   −   1   )       +   1     )       δ       (     m   −   1     )           ]     /     δ   m     +   1,                                                                                                                     (   2   )           
, where n 1  and n m  - number of elements of the first group and group with the number "m", accordingly; K 1 , K (m-1)  and K m  - ratio of the value of the size of the last element of the group to the value of the pitch of sizes of this group for the first group, groups with the number "m-1" and with the number "m", accordingly; A 11  - size of the first element of the first group of the set; δ 1 , δ (m-1)  and δ m  - pitch of sizes of the elements of the first group, groups with the number "m-1" and with the number "m", accordingly, and values of ratios K 1 …K m  are in intervals of integer natural numbers 100≤K 1 ≤201, 51≤K 2 ≤150, 8≤K 3 ≤20, 5≤K 4 ≤50, 1≤K 5 ≤10), are subject to dependence (3)          K   m     =     A     n   m   −   m       /     δ   m                                                       (   3   )
