Why Product Certification Matters

Product certification acts as an indicator of that product’s safety, reliability, and quality, but it can be difficult to make sense of all the different certifications. Many of the most common certifications are those recognized by OSHA, which we include below. And of course, we list what certifications we get for all of our own products.

Continue reading below for more on product certification and why it matters.

Value-branded products are everywhere. New companies seem to pop up overnight. Product certification is one of your best tools to tell the quality from the questionable, or reliable from the risky.

Buying on price and availability can expose users to avoidable risk. Product certification lets you know that a product is safe and reliable. It’s a benchmark for product quality, a guidepost leading you to reliable manufacturers.

Reputable companies work to minimize and eliminate risk. Product certification demonstrates their commitment to quality and safety. It affirms that products have passed specific performance and quality assurance tests.

Government purchasing standards usually require product certification. Businesses, schools, and other groups are following suit. The availability of low-cost, quick-to-market products is increasing, making it more important than ever to affirm product certification.

Product Certification Signals Quality and Safety

Many electronic devices are well-made and reliable. Many others are made using shortcuts with quick profits in mind. It can be difficult to tell the difference. Product certification is an important clue.

Products without certification marks may function as intended (for a while). But they’re more likely to be cheaply produced. Uncertified products are more likely to be made from sub-standard components. Components that would fail product safety and quality standards if they had been submitted for testing.

Confirming that electronic and computing products are certified:

  • Safeguards health and safety
  • Protects productivity and profit
  • Ensures reliability
  • Guards against liability

Health and safety. Electronic devices that qualify for product certification are safer to use. They’ve been tested to meet the highest standards for protecting user health and safety.

Productivity and profit. According to OSHA, providing a safe work environment saves companies money. Safe workplaces are more productive. Employees are more comfortable. And motivation and morale are higher.

Work-related injuries and illnesses sap company resources. They increase workers’ comp claims and retraining costs. They lead to lost workdays and lower productivity. And they impair the efficient delivery of products and services.

Liability. Using safety-certified products and components is often required by law. Government agencies are a case in point. Another example: the National Electrical Code (NEC) requires the use of UL-listed products.

Product certification is a good idea even when it’s not required by law. Using a product tested and certified for safety reduces the risk of legal action. Product certification signals that a company has confidence in their product. And cares about customer safety. It protects against potential liability in the event an injured employee files suit.

Failing to use certified products can result in denial of insurance claims. Even when it’s not required by law. This can result in costly legal battles.

Reliability. Getting products certified is a lengthy, costly process. Certification marks identify whether a company is committed to the market. A certified product can be counted on to perform safely. It’s also a good bet that the company can be counted on for support, too. That’s important for ensuring reliable customer service in the long run.

NRTLs – The Product Certification Authorities

Meaningful product certifications come from legitimate, qualified test labs. This can be a government organization, the Federal Communications Commission (FCC). Most often, it’s a private, organization recognized as an authority in product safety.

Test labs are themselves “certified” by the Occupational Safety and Health Administration (OSHA). OSHA assesses and qualifies these labs to be a Nationally Recognized Testing Laboratory (NRTL).

OSHA developed the NRTL program to ensure that equipment was tested and certified for safe use in the workplace. This program oversees the certification of the certifiers. It ensures that these private-sector companies meet stringent requirements. These companies must:

  • Be capable of testing and evaluating equipment for conformance with appropriate test standards.
  • Provide adequate controls to identify certified products.
  • Conduct follow-up inspections of actual production.
  • Be independent of users, manufacturers, and vendors of the certified products.
  • Have effective procedures for producing its findings and for handling complaints and disputes.

Each NRTL offers a range of test standards. Each has its own unique registered certification mark(s). These marks designate compliance with the applicable safety test standards. The safety standards are developed by organizations like the American National Standards Institute (ANSI) and Underwriters Laboratories (UL).

Reputable manufacturers submit the product to an NRTL for testing. After successful completion, they can use the certification mark. An NRTL certification mark on a product, packaging or related materials is a sign of quality and safety.

It’s important to note that OSHA’s authority is limited to employers. OSHA does not require makers or suppliers of products to obtain NRTL certification. But ethical, reputable and concerned companies usually do anyway, especially when products require approval under OSHA standards. Some go above and beyond and certify non-OSHA required products for safe, reliable use.

OSHA currently recognizes 19 NRTLs. Among these are the familiar UL and TUV certifications. A certification mark from any of these organizations means that the product meets OSHA’s stringent requirements. It ensures buyers that it’s been tested by an accredited, competent and objective third party.

The range of possible product certifications is extensive. Key certification marks to look for on enterprise-grade technology products include the following: 

Certification Entity Mark Significance

Safeguard Users: Confirm Product Certification

Your business or school district may not require the use of safety-certified products. Nonetheless, it makes good sense to protect users. Poor workmanship and failure to meet safety standards can jeopardize health and safety. It can expose your school or company to liability. It can decrease morale, and make users less productive. Using products certified by a nationally-recognized testing lab is an easy safeguard. For your users and your bottom line.
