What Standards Can TÜV Rheinland Evaluate to?
The choice of a suitable standard depends on the type of equipment. TÜV Rheinland engineers decide on a case by case basis which standard or combination of standards best matches the type of equipment that needs inspection. We evaluate to standards for electrical and electromechanical equipment as written by UL, NFPA, ANSI, CSA, etc. Some of the most commonly used standards are:
- UL 508A Safety of Electric Control Panels
- NFPA 79 Safety of Industrial Machinery
- UL 987 Safety of Electric Tools
- UL 73 Safety of Motor Operated Appliances
- UL 60950 Safety of Information Technology Equipment
- UL 60601-1 Safety of Medical Equipment
- SPE 1000 Model Code for field evaluation of electrical equipment
Field Evaluation and Field Labeling of Photovoltaic Systems
TÜV Rheinland provides field labeling services and evaluates residential and commercial photovoltaic installations to the National Electric Code 2005; Article 690: Photovoltaic Systems. If the photovoltaic modules or CPV's (Concentrator photovoltaic modules) are mounted on tracker systems, TÜV Rheinland will assess the moving parts and the control system to ANSI/ISO 12100-2 for the mechanical safety, and UL 508A/NFPA 79 for the electrical safety to satisfy the Authority Having Jurisdiction (AHJ).
Four Steps to Getting Approval
It only takes four steps for our experts to help you get approval for your machines:
Contact TÜV Rheinland and provide us with the technical documentation for your machines.
2. Preliminary Audit
We will perform an on-site preliminary audit of the machine, inspect your production facilities, corresponding technical documentation, instructions for installation and operations.
3. Audit Report
Our experts will issue an audit report upon successful completion of the audit, determining if your machine meets local requirements and compliance to standard.
4. Final Audit
Upon installation, our experts will perform a simplified on-site acceptance procedure for the machine and issue a positive FES Report, if the machine meets all requirements. The system will then be approved by the local AHJ (Authority Having Jurisdiction) representative.
The following safety relevant components are inspected for suitability of electrical rating and NRTL (Nationally Recognized Testing Lab) approval.
The equipment's design is visually inspected with particular attention to the following areas:
Cables and Wires
Use of Listed Components
Proper conductor protection
Accessibility of live parts
Guarding of moving parts
Suitability of enclosures
Pinching, crushing, falling hazards
Suitability of material
Proper wire bending spaces
Proper Transformer protection
Ground and bonding
Guarding of Live Parts
Accessibility of moving parts
Availability of suitable markings
Proper Motor protection
Required Additional Safety Testing
In addition to relevant construction evaluations, the equipment will also be tested for compliance to safety requirements. The tests may vary depending on the type of equipment. However, some of the most common tests are:
Grounding Continuity Test:
Testing for proper grounding and bonding of the whole equipment.
Dielectric Voltage Withstand Test (Hi Pot Test):
Testing for adequate spacing between conductive parts. Test is performed between primary and ground and primary and secondary of the unit.
Input Current Test:
Measuring the input current of the unit during maximum load operation and evaluating the suitability of protection mechanisms such as fuses, circuit breakers, etc.
Strain Relief Test:
Measuring the strength and suitability of strain relief through push and pull tests.
Test the proper operation of any emergency stops for reliability and proper functioning.
Rain Tests (for outdoor use equipment):
Equipment is exposed to simulated rain conditions for up to four hours. Following the test, the equipment is inspected for ingress of water and tested for dielectric breakdown and insulation resistance.
Tests the suitability and performance of all interlocks giving access to live parts and moving components.
Legal Standards in the US and Canada
The applicable regulations can be found in articles 90-7, 110-2, and 110-3 of the NEC (“National Electric Code”, and 29 CFR 1910.301 (subpart S) of the OSHA (Occupational Safety and Health Administration). Both organizations require official approval of all electronic devices and systems in the US and Canada. Approval can be proven via a “listing” or a “field evaluation”.
