² If pos­sible, the first meas­ure­ment (ac­cept­ance meas­ure­ment) or in­spec­tion must be car­ried out with­in three months, but no later than twelve months after the com­mis­sion­ing of the new or ret­ro­fit­ted in­stall­a­tion.

b.

every two years for oth­er com­bus­tion in­stall­a­tions

c.¹⁰
