Machinery Directive Annex IV: Special Machinery Categories and Conformity Procedure
Annex IV identifies specified machinery and safety-component categories relevant to procedure selection.
Continue with the relevant decision step
Direct answer
Annex IV identifies specified machinery and safety-component categories relevant to procedure selection. It is not a certificate name. Compare the machine's technical function with the list and examine whether harmonised standards cover all relevant safety requirements before deciding which permitted route applies.
Decision and evidence
Document the category and coverage analysis. Verify any required body's scope and the applicable legislative transition before commissioning tests or promising an assessment outcome.
Technical basis
For machinery, risk assessment, essential health and safety requirements, the technical file, declarations and CE marking must form one traceable chain under the applicable machinery legislation.

Can a single custom-built machine be exempt from CE requirements?
Producing one unit does not by itself create a general exemption. Assess the product, placing on the market or into service, and applicable exclusions. Custom design does not remove necessary files, risk assessment and declarations. Separate testing, technical assessment and any third-party stages according to the machine.
Does connecting CE-marked machines into a line require further work?
Assess whether shared control and function create an assembly. Feeding, transfer, trapping and coordinated stopping hazards may be absent from individual files. Identify the assembly's responsible manufacturer and conformity route. Component CE marks do not establish assessment of every integrated-system risk.
