An inspection machine (ASIM) for inspecting containers such as vials, said inspection machine (ASIM) comprising: one or more inspection stations (IS1 - ISn) comprising sub-components from the list of mechanical, optical and electrical sub-components, each inspection station (IS 1 - ISn) being arranged to perform a container analysis routine for inspecting a container and to establish a container-dependent inspection result; a control unit arranged to analyse said container-dependent inspection results related to the container and obtained from the one or more inspection stations (IS1 - ISn), and on the basis thereof determine if the container fulfils one or more grounds for rejection; and a sorter at least partly controlled by the control unit to divert the container if the control unit has determined that the container fulfils one or more grounds for rejection; characterised in that the inspection machine (ASIM) further comprises a system test arrangement (SSO, SO, SW3, ECU) in connection with the one or more inspection stations (IS1 - ISn), the system test arrangement (SSO, SO, SW3, ECU) comprising at least one standard object (SO; HVSO; LDSO; FCSO; ALSO; UFSO) having one or more specific characteristics that are arranged to test specific of said sub-components of the one or more inspection stations (IS1 - ISn); wherein at least one of the one or more inspection stations (IS1 - ISn) are further arranged to perform a standard object analysis routine, which is different from the container analysis routine, and which is a dedicated individual test algorithm for inspecting a standard object (SO; HVSO; LDSO; FCSO; ALSO; UFSO) and to establish a standard object-dependent inspection result; said standard objects (SO; HVSO; LDSO; FCSO; ALSO; UFSO) and said standard object analysis routines being arranged to establish standard object-dependent inspection results that represent status information about said sub-components of said inspection stations (IS 1 - ISn)s; and wherein said inspection station (IS1 - ISn) or control unit is arranged to analyse said standard object-dependent inspection results related to the standard object (SO; HVSO; LDSO; FCSO; ALSO; UFSO) and obtained from the at least one of the one or more inspection stations (IS1 - ISn). one or more inspection stations (IS1 - ISn) comprising sub-components from the list of mechanical, optical and electrical sub-components, each inspection station (IS 1 - ISn) being arranged to perform a container analysis routine for inspecting a container and to establish a container-dependent inspection result; a control unit arranged to analyse said container-dependent inspection results related to the container and obtained from the one or more inspection stations (IS1 - ISn), and on the basis thereof determine if the container fulfils one or more grounds for rejection; and a sorter at least partly controlled by the control unit to divert the container if the control unit has determined that the container fulfils one or more grounds for rejection; characterised in that the inspection machine (ASIM) further comprises a system test arrangement (SSO, SO, SW3, ECU) in connection with the one or more inspection stations (IS1 - ISn), the system test arrangement (SSO, SO, SW3, ECU) comprising at least one standard object (SO; HVSO; LDSO; FCSO; ALSO; UFSO) having one or more specific characteristics that are arranged to test specific of said sub-components of the one or more inspection stations (IS1 - ISn); wherein at least one of the one or more inspection stations (IS1 - ISn) are further arranged to perform a standard object analysis routine, which is different from the container analysis routine, and which is a dedicated individual test algorithm for inspecting a standard object (SO; HVSO; LDSO; FCSO; ALSO; UFSO) and to establish a standard object-dependent inspection result; said standard objects (SO; HVSO; LDSO; FCSO; ALSO; UFSO) and said standard object analysis routines being arranged to establish standard object-dependent inspection results that represent status information about said sub-components of said inspection stations (IS 1 - ISn)s; and wherein said inspection station (IS1 - ISn) or control unit is arranged to analyse said standard object-dependent inspection results related to the standard object (SO; HVSO; LDSO; FCSO; ALSO; UFSO) and obtained from the at least one of the one or more inspection stations (IS1 - ISn).
