What is a SCIOS Scope 8 PI inspection?

A Scope 8 PI inspection is intended for low-voltage installations in commercial buildings, utility premises, healthcare facilities and other non-residential buildings - think office complexes, shops, workshops or factory halls. It's based on the NEN 3140 standard, which sets requirements for working safely with and on electrical installations. PI stands for "periodic inspection": BVo Advies carries out this inspection on a fixed, recurring schedule, so your installation's safety stays continuously safeguarded. A Scope 8 PI inspection consists of:
- Visual inspection of the installation and wiring
- Measurements and tests, such as insulation resistance, earth resistance and leakage currents
- Assessment of documentation, including diagrams and maintenance records
- A report with findings and recommendations
- A report suitable for your insurer
This inspection may only be carried out by a certified SCIOS scope 8 PI inspector. At BVo Advies we work exclusively with certified professionals who are up to date with current standards and regulations.
How often is the inspection carried out?
The PI in Scope 8 PI stands for periodic inspection. The law sets no fixed interval. The installation manager decides it based on the use, environment and condition of the installation, as NEN 3140 requires. Using the risk method in annex I of NEN 3140, that comes out between 1.5 and 14 years. If your insurer sets a fixed term, the shorter of the two applies.

- Your insurer requires it
- Your electrical installation is modified or extended
- After a fire or other incident at your business
