Warnock Hersey logo

Warnock Hersey Mark (WH) is a leading North American product safety and performance mark for building and construction products.

The WH mark affixed to a product indicates its compliance with relevant building codes, association standards, and product safety and performance standards. Nearly 80% of wooden fire doors in North America bear the WH mark.

The range of products bearing the WH mark, as tested by NormalTCI, includes fire doors, construction hardware, as well as fireplaces, pipelines, and building products. Attaching the WH mark to your products demonstrates your commitment to inspectors, builders, and end users regarding product safety, performance, and quality. The WH mark also signifies that the manufacturing site of the product has undergone regular follow-up inspections to ensure that the originally certified products remain compliant.

● Fire resistance test

The new transformation of Warnock Hersey Mark

The new WH-ETL mark combines two of the most recognized certifications in North America, namely the WH and ETL marks, into a single mark. By integrating the WH fire safety mark with the ETL electrical safety mark, regulatory authorities and building code enforcement officials can more easily identify the certification status of products.

The new WH-ETL logo signifies to customers:

The product complies with building regulations and industry standards that align with the industry's development direction;

● Meet both product safety and performance standards;

● Simplified the authentication process;

●More rapidly expand the market;

● Simplified and more recognizable product labels;

● Prove that the manufacturer's product production process is regularly tracked and monitored to ensure that product quality remains consistent with that when it was initially certified and inspected.

The new WH-ETL mark signifies a new era for the WH mark and will be utilized in all new fire safety certifications. NormalTCI is committed to ensuring a smooth transition to the new mark and will collaborate closely with our clients to guarantee their seamless entry into the markets they aspire to expand into.

Common problems:

Can the WH-ETL mark be accepted by regulatory authorities?

Certainly, the WH mark and the ETL mark are currently widely accepted by regulatory authorities in North America, and combining them would merely add to their existing credibility. Over the past few years, both marks have undergone design changes, but these alterations have not been rejected by the public. The new WH mark is merely an extension of the original, and it will continue to be highly recognized by regulatory authorities.

Is the WH logo not used anymore?

The WH mark is one of the renowned certification marks in the building materials industry, having been in use for over a century. The introduction of the new mark will not render the original one obsolete; rather, it serves merely as an extension. Combining WH and ETL is another approach to strengthen these two brands, ensuring that the new mark keeps pace with industry advancements.

What about the existing WH logo?

From now on, manufacturers are authorized to use the latest logo on their products. They have a five-year transition period to use the new logo on all products, packaging, literature, and websites before January 1, 2018. Currently, products already on the market will not be required to immediately switch to the new label.

Will the WH-ETL mark increase costs?

Of course not. Combining the two logos into one enhances the advantage and applicability of the logo, but it will definitely not incur additional costs for customers.

●How long is the transition period for the WH-ETL mark?

For products that have obtained WH certification, NormalTCI will immediately grant the right to use the WH-ETL mark. For customers who already hold the WH mark and have run out of labels before January 1, 2018, NormalTCI will provide new WH-ETL label.
