SCIOS (Systeemcertificatie Inspectie en Onderhoud van Systemen) is a Dutch certification scheme that sets standards for the inspection and maintenance of technical systems, including electrical and heating systems. It's important to note that the guidelines for SCIOS certification may differ by country.

A Scope inspection is an electrotechnical assessment certified by SCIOS. There are various types of inspections, such as Scope 8, 10, and 12, which focus on tasks like verifying the safety of electrical installations (Scope 8) or identifying fire risks (Scope 10). It is important to note that requirements for these inspections may vary depending on the country.

NEN 3140 originated from the Working Conditions Act (Arbowet). This law requires employers and employees to create an electrically safe working environment. NEN standards help ensure this electrical safety. While the NEN standard is not a law, it represents "best practices."

NEN 3140 is based on the European standard NEN-EN 5110. All relevant requirements for low voltage are included in NEN 3140.

The standard committee for low-voltage electrical installations, also known as NEC 64, is responsible for standards including NEN 3140, which pertains to the safety of electrical installations.

Upon passing your NEN 3140 exam, you will receive the NEN 3140 certificate. The NEN certificate is not (yet) registered in a national registry. However, the NEN 3140 certificate document is recognized by employers.

After obtaining your NEN personal certificate, you are required to re-take the exam within three years. During this period, NEN 3140 guidelines may have been updated, so it is advisable to re-enroll in NEN 3140 training.

Yes, the Working Conditions Act requires both employers and employees to create an electrically safe working environment. On the job, many clients increasingly demand that self-employed professionals (ZZP’ers) hold a valid NEN 3140 Certificate. The NEN 3140 guidelines help ensure this electrical safety.
