What are UL standards?

UL standards can be used to assess the electrical safety and flammability of many categories of products. UL standards might also cover aspects such as performance, and sustainability.

UL safety standards help ensure the reduction of injury to customers, and potential risks and dangerous occurrences brought about by design problems, improper labeling, and more. UL standards enjoy recognition across the North American market for being a benchmark of safety. As such, UL standards are adopted by top industry leaders worldwide.

What is Underwriter Laboratories?

Underwriter Laboratories is a US company that has been accredited by the American National Standards Institute (ANSI) and the Standards Council of Canada (SCC).

UL focuses on testing and certifying a large array of products like consumer electronics and medical devices for safety compliance before they are placed in markets around the world. Over more than a century, UL developed more than 1,500 of its own standards to test the safety of electronics and other products.

It is paramount to ensure a product’s safety by developing safety standards. This necessity applies especially to newer products for which no regulations or standards exist yet.

UL Standards List

UL has developed different types of standards, against which a product’s electrical safety, flammability, sustainability, performance, and other aspects are tested.

Below we list different types of standards relevant to consumer products. You can find more standards on the UL website.

Electrical Safety Standards

UL develops electrical safety standards in order to prevent risks such as electric shocks or burns for the user. Here we list some examples of these standards:

a. UL 62368-1 – Audio/Video, Information, and Communication Technology Equipment – Part 1: Safety Requirements

b. UL 2054 – Household and Commercial Batteries

c. UL 749 – Household Dishwashers

d. UL 1023 – Household Burglar-Alarm System Units

Flammability Standards

UL develops testing standards pertaining to the flammability of items so as to make sure said items do not easily catch or propagate fire. Here are some examples of these standards:

a. UL 94 – Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances

b. UL 340 – Standard for Tests for Comparative Flammability of Liquids

c. UL 1694 – Standard for Tests for Flammability of Small Polymeric Component Materials

d. UL 127 – Standard Corner Wall Method of Test for Flammability Characteristics of Non-Melting Foam Plastic Building Materials

Sustainability Standards

UL develops standards concerning the sustainability of various products to ensure that they do not pose harm to the environment or deplete natural resources during the manufacturing process or everyday usage by consumers. Here we list some of these standards:

a. UL 115 – Sustainability for Thermal Insulation

Amazon and UL standards

Amazon sellers should be aware that Amazon might require compliance with UL standards. This is the case even if UL compliance is not a regulatory requirement for said product.

As such, UL standards are practically made mandatory by Amazon on its US marketplace for a wide range of electronics. Failing to provide valid UL test reports, issued by an ISO 17025 accredited company, can result in your listing being denied or removed at a later date.

Power Banks

For example, Amazon requires lithium power banks to be tested according to UL 2056. Amazon also lists UL 2054 or UL/CSA 62133 for the internal battery, and UL/CSA 60950-1 or UL/CSA 62368-1 for the power bank – as an acceptable alternatives.

Other Electronics

Power banks are not the only products that may need to be tested for compliance with UL standards. The list of products for which Amazon requires UL compliance includes but is not limited to the following:

a. E-mobility devices (UL 2272 and UL 1642 / UL 2054 / UL 62133-2)

b. E-bikes (UL 2849)

c. Hand-supported hair dryers with immersion protection plugs (UL 859 / UL 1727)

d. Space heaters (UL 1278)

e. Seasonal and Decorative Lighting Products (UL 588)

f. Portable generators and portable inverter generators, portable power inverters (UL 2201 [Ed 2], UL 2743 / UL 458)

g. Portable Automotive Jump Starters (UL 2743)

h. Personal floatation devices (UL 1177 / UL 1180 ; UL 1123 / UL 1517 / UL 1180 ; UL 12402-5)

i. Mobile Phone / Laptop Computer Batteries and Chargers (UL 2054 ; UL 62133 ; UL 60950-1 ; UL 62368-1 ; UL 1310 ; UL 2089)

Are UL standards mandatory in the United States?

Although compliance with UL standards is often voluntary. That said, that doesn’t really change the fact that you must ensure that your products are compliant with the relevant UL standards – especially in the US.

Importers and manufacturers are responsible for the safety of their products, which – is found to be non-compliant with relevant regulations or being unsafe for any reason – might be recalled by the authorities, and removed from Amazon and other marketplaces. Importers and manufacturers of unsafe products also risk being subject to major fines, and legal action.

This is the case regardless of whether or not UL standards are voluntary.

Thus, testing your product against recognized standards such as UL standards can help to assess product compliance, and verify product safety. Amazon and other marketplaces or retailers might also require sellers to prove that their products comply with UL standards, even if doing so is voluntary.

Are UL standards recognized in the UK?

Presumption of conformity with UK regulations is generally based on British Standards (BS). However, if no British Standards exist for a product, other international standards., such as UL or ATSM standards, may be used to demonstrate the safety of a product. This is, however, rarely the case.

Are UL standards recognized in the European Union?

Presumption of conformity with EU directives and regulations is generally based on EN standards. In some cases, national standards, such as DIN 4102 German standards for fire resistance, can also be used.

If there are no relevant EN or national safety standard for a product’s been tested against, relevant international standards may be utilized instead, including UL standards. Again, this is rarely the case as there are usually corresponding EN standards in existence.

What is the difference between UL and ETL?

UL develops its own standards. Meanwhile, ETL is a testing and certification scheme that tests products according to relevant standards – including UL standards. Further, ETL was created by Intertek and aimed at demonstrating compliance with standards and regulations in North America. Possibly due to the fact that there is no equivalent to the CE mark in the US and Canada.

Both UL and ETL are recognized by OSHA and Nationally Recognized Testing Laboratories (NRTLs) in the US.

Are UL standards available for free?

UL standards are not available for free and must be purchased. The only exception is represented byUL Environment Standards, which can be downloaded as a PDF at no cost.

A single standard can cost up to US$798 in PDF format, and up to US$998 if you choose to purchase the hardcopy. You can also decide to purchase a 3-year subscription package for a given standard, which also includes revisions, bulletins, and proposals. As such, subscriptions are more expensive.

Under this plan, a standard in PDF format costs up to US$1,592, and hardcopy versions cost up to US$1,990.

How much do UL standards cost?

As already mentioned, UL standards for different consumer products will have different costs. We list below four examples:

a. Standard 60065 – Standard for Audio, Video and Similar Electronic Apparatus – Safety Requirements – US$514 – US$1,284

b. Standard 60730-2-12 – Standard for Automatic Electrical Controls – Part 2-12: Particular Requirements for Electrically Operated Door Locks – US$205 – US$513

c. Standard 60745-2-3 – Hand-Held Motor-Operated Electric Tools – Safety – Part 2-3: Particular Requirements for Grinders, Polishers and Disk-Type Sanders – US$530 – $1325

d. Standard 60335-2-8 – Household and Similar Electrical Appliances – Safety – Part 2-8: Particular Requirements for Shavers, Hair Clippers and Similar Appliances – US$200 – US$500

Where can I buy UL standards?

While UL Standards are sold on the UL Standards Sales Site, these can also be purchased on other sites, including:

  • IHS Markit Standards Store
  • American National Standards Institute (ANSI) webstore
  • Beuth publishing DIN

UL Certification

Testing products according to UL standards can enable brands to use UL marks on the product, packaging, or part of promotional materials.  Doing so can signal to consumers that your product is safe and tested according to the relevant UL standards.

UL Marks Overview

  • UL Certified Mark
  • UL Listed Mark
  • UL Classified Mark
  • UL Recognized Component Mark
  • UL Performance Verified Mark

You can learn more about the different definitions on this page.

UL Certified Mark

Products bearing the UL Certified Mark have been Listed or Classified by UL, or both.

Examples of kinds of products certified by UL include:

  • Signaling alarms
  • Electronic equipment
  • Electrical components

UL Listed Mark

A product is considered to be UL Listed when samples of the product have been tested and deemed by UL to have met UL’s relevant safety standards, all of which are nationally recognized.

There are instances where products (especially industrial products) bearing the UL Listed mark have been evaluated by UL to be compliant with other safety requirements. In these cases, any marketing material may have to specify which additional safety requirements the product meets.

UL Classified Mark

UL Classified means that the product has been tested and evaluated by UL. But only for specific properties, with regard to a limited range of hazards, or for use under certain conditions.

Since UL Classified products have only been tested for specific properties, such as flammability, it is important to ensure that the UL Classified Mark is accompanied by a statement that indicates the specific scope of the classification.

Conversely, UL Listed products are deemed safe in a more broad sense.

UL Performance Verified Mark

UL Performance Verified means that samples of a product have been tested and evaluated against specific performance standards, for instance lighting energy efficiency. This helps to build credibility and consumer trust.

The main difference between a UL Performance Verified products and UL Listed or Classified products is that the former has been tested against performance standards, while the latter has been tested against safety standards.

UL Recognized Component Mark

In this case, UL tests components or materials, not end-use products. When the component or material has been tested and evaluated to have met the relevant UL standards, it is deemed as a UL Recognized Component.

Such components or materials are intended to be used in an end-use product or system that might then be eligible for UL listing or UL classification.

Examples of UL Recognized Components include:

  • Board mounted relays
  • Motors
  • Definite purpose contactors
  • (USA & EU)
