Unravelling the Mystery of Partly Completed Machinery: Understanding their Significance and Implications

The line between what constitutes a complete machine and what is considered a “partly completed” machinery can be somewhat blurry. The distinction between the two is crucial. It determines the application of safety regulations, standards, and also the responsibilities of manufacturers and users. In this blog post, we’ll delve into the intriguing world of partly completed machines, exploring what they are, why they matter, and moreover the implications they hold for safety and compliance.

Defining Partly Completed Machinery

A “partly completed machine” is a term used in the machinery industry to describe a piece of equipment that is not yet fully assembled and functional but is intended to become a complete machine once integrated with other components. These components can include various parts, modules, or sub-assemblies that, when combined, form a functional machine designed for a specific purpose.

Why Partly Completed Machines Matter

Safety and Compliance. The differentiation between a partly completed machine and a complete machine is pivotal in determining which safety regulations and standards apply. Incomplete machines often fall under different regulation requirements, as they may have different safety requirements and risks.

Responsibilities. Manufacturers, importers, and users of machinery have distinct responsibilities depending on whether the machinery is complete or partly completed. Understanding these roles is crucial for ensuring safety and compliance.

Customisation and Flexibility. Partly completed machines offer flexibility and customisation opportunities, as they can be integrated into various production processes and adapted to specific needs.

Cost-Efficiency. Manufacturers can benefit from cost savings when using partly completed machines as building blocks for various applications, rather than creating entirely new machines from scratch.

Regulations and Compliance

Partly completed machines often fall under the scope of different regulations, such as the Machinery Directive in the EU. Compliance requirements may include risk assessment, CE marking, and conformity assessment procedures. Users and manufacturers must be aware of the specific regulations and standards applicable to their partly completed machines to ensure compliance and safety.


Responsibilities for partly completed machines are typically distributed as follows:

Manufacturers. Manufacturers of partly completed machines must provide essential information, including risk assessments and instructions for further assembly. They should also declare conformity with relevant regulations and standards.

Users. Users of partly completed machines must complete the assembly process according to the manufacturer’s instructions and ensure that the final assembly complies with safety standards.

Integrators. Integrators are responsible for the assembly of partly completed machines. They should follow the manufacturer’s instructions and ensure the final machine is safe for use.


Partly completed machines occupy a unique and crucial space in the machinery and manufacturing industries. Their distinction from complete machines is more than just semantics. It directly impacts safety, regulations, and the responsibilities of all involved parties. Understanding these distinctions, adhering to relevant regulations, and ensuring safe assembly are essential for the continued success of the industry and the safety of workers and end-users. As the machinery landscape evolves, keeping an eye on partly completed machinery is key to progress and compliance.
