Key Takeaway

  • The ETL mark, operated by Intertek, is a widely recognized equipment safety certification program that ensures products meet stringent safety and sanitation standards, facilitating compliance with regulations and acceptance in various markets.
  • In today’s industrial landscape, ensuring equipment safety and compliance is more critical than ever. ETL certification is one of the most widely recognized ways to verify that equipment meets strict performance and safety standards. Operated by Intertek, the ETL mark signifies that a product has undergone rigorous third-party testing to comply with established regulations for safety, sanitation, and efficiency.

    For manufacturers, obtaining ETL certification not only ensures compliance with OSHA and other regulatory bodies but also builds trust with customers and facilitates market acceptance across industries. Whether for electrical, mechanical, or other specialized equipment, this certification serves as a key indicator of quality and reliability.

    Let’s take a closer look at what ETL certification entails and why it matters.

    What is ETL Certification?

    what is ETL certification

    The ETL mark, short for Edison Testing Laboratories, is, in part, an equipment safety certification program operated by the laboratory, Intertek. Intertek is one of the few NRTLs (Nationally Recognized Testing Laboratories), a third-party testing program which is overseen by OSHA. 

    The ETL Mark includes a number of different variations that are designed to fit within the safety and/or sanitation standards of the product, including the operating and purchasing regions.

    In order to be awarded the ETL mark, the manufacturer must undergo an intricate certification process, which includes a photograph, description, and a design/optional prototype submission, a quote agreement, official follow-ups, facility assessments, and more. After the process is completed, the manufacturer and/or user of the certified equipment can then affix an ETL mark using a robust equipment label that is built to last.

    ETL Certification Requirements

    To obtain ETL certification, manufacturers must meet several key requirements to ensure their products comply with industry safety and performance standards. The process involves thorough testing, documentation, and ongoing compliance.

    1. Product Compliance & Testing

    • Products must meet OSHA-approved safety standards and industry regulations (e.g., UL, ANSI, NFPA).
    • Testing must be conducted by an accredited laboratory such as Intertek to verify compliance.
    • Products are assessed for electrical safety, durability, and performance reliability based on applicable guidelines.

    2. Technical Documentation Submission

    Manufacturers must provide:

    • Schematics and wiring diagrams detailing the internal design.
    • Material and component specifications proving compliance with safety standards.
    • Installation and user manuals outlining proper usage and safety precautions.

    3. Factory Inspections & Ongoing Compliance

    • Initial facility inspection ensures that manufacturing processes align with certified standards.
    • Periodic follow-up inspections confirm continued compliance and quality control.
    • Any product modifications or design changes require re-evaluation to maintain certification.

    By meeting these stringent requirements, companies can earn the ETL Listed mark, signifying their commitment to safety, quality, and regulatory acceptance across various industries.

    ETL Certification Benefits

    OSHA NRTL

    Getting a product certified by a third-party laboratory is a compulsory step in guaranteeing that the user is compliant with any and all safety and sanitary regulations – but that doesn’t mean that there isn’t wiggle room when it comes to the selection of the third-party laboratory.

    For instance, UL (Underwriters Laboratories) grants a competing certification to Intertek’s ETL. Both labs are OSHA-recognized NRTLs that offer similarly-tested marks that are accepted in many of the same regions. The availability of alternative options is great news for the party seeking the certification. As pricing and testing schedules can vary with demand, it’s not unusual for manufacturers to flip-flop between UL and ETL certification for identical products. That said, companies that are shipping equipment for international use are generally more likely to select the ETL certification when possible, as customs agents, code inspectors, and other officials based outside of the United States or Canada are more familiar with the ETL Listed mark (more on this next).

    ETL Listed Mark Explained

    ETL Listed

    As mentioned, there are several different ETL certification marks that may be granted based on the design of the equipment’s corresponding standards, as well as the region in which it will be installed. One of the more versatile marks is the ETL Listed mark, the fastest-growing safety certification mark in North America. The ETL Listed mark is currently the most adaptable certification granted by Intertek. The process is similar to its classic ETL alternative, except that ETL Listed is specifically designed for both the United States and Canadian markets. Because both countries have such stringent safety laws, the certification is also recognized by many other international markets, too.

    For products that will be shipped to EU countries, ETL also has a variation of Listed called the ETL-EU Mark. This certification is the first of its kind and, like Listed, the mark is recognized in a host of other regions.

    ETL Sanitation Mark Explained

    Next is the ETL Sanitation Mark, which is designed to go hand-in-hand with the classic ETL certification as well as ETL Listed. The Sanitation certification has been established to ensure that both U.S. and Canada-based food, health, and beauty manufacturing sites are in full compliance with all measures relating to sanitation. To maintain this certification, the manufacturing site must undergo a series of future testing and inspections.

    ETL Verified Mark Explained

    The ETL Verified Mark is something of an anomaly as it has been established for two distinct purposes: 1) to indicate that the product is safe and in compliance with all applicable standards, and 2) to serve as a differentiator for products and brands in competitive markets. This means that products that are ETL Verified are tested for both safety and effectiveness.

    For instance, ETL Verified ensures that:

    • Cabling products are verified for bandwidth
    • Dishwashers are verified for cleaning ability
    • LED Traffic Signals are verified for design qualification testing requirements of ITE specifications
    • Verification of NFPA 1851 Independent Service Providers (ISP) are verified organizations involved with repairing and maintaining firefighting garments

    As illustrated, products and facilities that bear an ETL mark are made to undergo every OSHA-mandated testing standard. Additionally, some ETL-marked products also give companies a competitive advantage within their respective markets. Intertek, as well as all competing NRTLs, are here to provide the manufacturer with important testing processes and methods to acquire the certifications.

    Final Thoughts

    In today’s industrial landscape, ensuring equipment safety and compliance is paramount. ETL certification, managed by Intertek, serves as a widely recognized indicator that products have undergone rigorous third-party testing to meet stringent safety, sanitation, and performance standards.

    This certification not only signifies adherence to OSHA and other regulatory requirements but also enhances customer trust and facilitates market acceptance across various industries. Manufacturers seeking ETL certification must navigate a comprehensive process, including detailed documentation, prototype evaluations, and facility assessments, culminating in the authorization to display the ETL mark on their equipment.

    Obtaining ETL certification offers numerous benefits, such as

    • Flexibility in choosing between recognized testing laboratories like Intertek’s ETL and Underwriters Laboratories (UL)
    • Allowing manufacturers to select options that best align with their cost and scheduling needs

    The ETL Listed mark, in particular, is gaining prominence as a versatile certification recognized not only in North America but also internationally, streamlining compliance for products destined for global markets.
