Low Voltage Equipment and Components

At Intertek, we understand that product safety and compliance are essential for low voltage equipment and components. That’s why we offer a comprehensive range of ASTA certification services to meet the varied needs of manufacturers and suppliers.

This includes the globally recognised ASTA Certification for end-to-end testing and licensing, the ASTA Diamond Mark for visible proof of safety and quality, and the specialised ASTA Type Test Certification for bespoke or long-lifecycle products. Together, these services help you meet international standards, stand out in the market, and build confidence with your customers.  

Intertek’s  ASTA team delivers industry-leading services for the certification and approval of switchgear, wiring devices, circuit protection, of low-voltage equipment.

The ASTA Mark demonstrates to customers, utilities, electrical contractors, consultants, specifiers , and customs or port authorities that your product meets the relevant standards. ASTA Certificates and Licences also serve as robust evidence of product compliance in the event of a product liability challenge.

ASTA, founded in 1938, has been part of the Intertek family since 2007, and has continued to deliver the trusted testing and certification services it’s known for. Our experts actively shape standards in the low voltage field, contributing at national and international levels

ASTA Certificates and Test Reports are issued following testing at Recognised Testing Laboratories (RTLs), which are independently and rigorously assessed by Intertek ASTA. These are the only certificates granted based on testing witnessed by an ASTA Observer, who is technically responsible to Intertek for ensuring the accuracy and validity of the testing process and final report. Intertek’s global network of more than 40 test laboratories operates under the Intertek Recognised Testing Laboratory (RTL) scheme to fully support ASTA Certification.

Trusted and recognised Certification for Global Markets

ASTA Certificates and ASTA Test Reports are internationally recognised and hold a particularly high profile in Asia and the Middle East, where they are often specified by major end-users.

Key benefits of ASTA Certificates:

• Demonstrate that your product has been independently tested for compliance with the relevant clauses of applicable standards
• Support declaration of conformity for different markets 
• Help quality brands stand out in the supply chain
• Provide manufacturers with an added layer of protection against potential legal action
• Simplify vendor approval processes, potentially reducing the need for multiple customer audits.

ASTA Diamond Mark

The ASTA Diamond Mark strengthens your product’s declaration of safety and confirms that it meets the appropriate standards – a clear demonstration of your commitment to high-quality manufacturing.

Widely recognised across the industry, the ASTA Diamond Mark supports declarations of conformity and technical file requirements needed for CE Marking within the EU.

The mark applies to a broad range of low voltage electrical products, including plugs, socket outlets, adaptors, consumer units, busbar trunking systems, fuses, switches, and busbar trunking systems etc. Products carrying the ASTA Diamond Mark are manufactured in factories that undergo regular inspections, with at least one audit per year to ensure safe, consistent production. Ongoing assessments by the certification body further confirm that products continue to meet the relevant safety standards.

Key benefits of the ASTA Diamond Mark and Licences:

• Confirms that products  meet the relevant safety and performance standards, including qualitative processes through independent, third-party validation.
• Demonstrates your commitment to quality, helping to build trust with your customers and end-users.
• Supports regulatory requirements, including CE Marking for the EU market.
• Reduces the risk of non-compliance and associated legal or market access challenges.
• Simplifies vendor approvals and strengthens your position in the global supply chain.
• Often listed within buyers specification 

Type Test Certification

The ASTA Type Test Certification service is designed specifically for manufacturers of bespoke  products in the electrical Transmission and Distribution sector. It offers independent verification that these products meet the specific performance and safety standards.

This certification is increasingly requested by electrical contractors, project specifiers, and procurement teams who need assurance that the equipment they select meets the necessary technical and performance requirements.

Key benefits of ASTA Type Test Certification:

• Confirms that your product has been tested and verified to meet the relevant international standards.
• Strengthens your product’s reputation for quality and safety.
• Supports market access and procurement processes by providing trusted evidence of compliance.
• Provides a competitive advantage in winning tenders and securing contracts.
• Optimization of testing requirements for multiple range/ratings of the products.
• Certificates can be upgraded to align with updated editions of relevant standards, ensuring continued compliance.
• A single (standalone) certificate can be issued covering all testing, provided the product design remains the same throughout.
• Tests at manufacturer  laboratory reduces both time and cost while offering greater flexibility
• Product range certification reduces the need for prototypes, shipments, travel, and testing, which in turn helps lower CO₂ emissions and overall carbon footprint.
• Reinforces customers brand’s commitment to delivering safe and reliable equipment.

ETL Certification Mark

Intertek’s ETL Certification provides manufacturers of low voltage components with a trusted pathway to product safety compliance for North American and global markets. Backed by Intertek’s status as a Nationally Recognized Testing Laboratory (NRTL) in the U.S. and a Standards Council of Canada (SCC)-accredited Certification Body, the ETL Mark demonstrates that your product has been independently tested and certified to applicable safety standards, such as UL, CSA, and ANSI.

The ETL Mark is widely accepted across retail, industrial, and commercial sectors and delivers immediate recognition of compliance to electrical safety requirements. Intertek’s streamlined testing and certification process helps manufacturers reduce time-to-market while ensuring adherence to relevant codes and regulatory requirements.

With testing available at Intertek laboratories or at your own, our ETL Certification program supports flexible project timelines and cost-effective certification strategies.

Key benefits of ETL Certification for low voltage components:

• Confirms compliance with relevant North American and international safety standards (e.g., UL, CSA, ANSI)
• Demonstrates third-party validation to retailers, inspectors, and end users
• Supports faster market entry with Intertek’s responsive testing and certification timelines
• Accepted by Authorities Having Jurisdiction (AHJs) throughout the U.S. and Canada
• Integrated with additional testing services such as performance, environmental, EMC, and functional safety to simplify the path to global market access
• Supported by Intertek’s global network of engineering and certification experts

The ETL Mark helps manufacturers of components such as circuit breakers, contactors, switches, transformers, and control devices confidently meet regulatory demands, reduce risk, and grow their presence across regulated markets.
