Smithers, a leading provider of testing, consulting, information, and compliance services, announced today that it has expanded its scope of accreditation to include ISO 19447 testing. The testing will take place at Brimley, Michigan's Smithers Winter Test Center (SWTC).

ISO 19447 is a standard method for determining the relative ice grip performance of passenger car tyres. The test method is similar to ECE R117 C1 Braking, which is awaiting European approval. These techniques are included in the EU's new Ice Grip (Alpine) label. The Ice Grip pictogram is displayed for winter tyres that have proven ice braking performance. This is a distinct label from the 3-Peak Mountain Snowflake (3PMSF) Snow Grip symbol.

"There is building demand for ISO 19447 testing right now, and very few companies who offer it. That's largely due to the fact that ISO 19447 requires a prepared surface and a fairly extreme winter environment," said Eric Pierce, Principal Engineer at Smithers Winter Test Center.

"At Smithers, we have the experience to prepare the specialized surface required for ISO 19447 and the ideal environment, putting the latest ice grip test methodology right at our clients' fingertips."

The ISO 19447 testing is carried out on a flat, polished ice surface. The surface must be prepared for at least an hour prior to testing, and the ambient temperature must be between -15 and 4°C. The temperature of the ice must be between -15 and -5°C. After fresh surface preparation, nine test runs are completed three times on different days or surfaces. Each nine-run sequence's highest and lowest scores are deleted, and the remaining data is used to calculate ice grip.

"As snow and ice traction testing methods for tires evolve, our goal is to continuously expand our capabilities at our proving grounds so our clients can keep pace with the latest innovations," said Jim Popio, PhD, Vice President, Smithers Materials Science and Engineering Division.

"The addition of ISO 19447 to our scope of accreditation is one of many investments we've made in recent years to ensure a world-class experience for our valued clients at the Smithers Winter Test Center."

The Smithers Winter Test Center (SWTC) in Brimley, Michigan, is a winter proving ground with over 800 acres of snow, ice, and bare pavement surfaces and courses. OEMs and tier suppliers use the facility to test and evaluate vehicle systems, tyres, and components under the unique challenges of extreme cold and hazardous road conditions. In 2023, the facility will celebrate 50 years of service to the automotive and tyre industries.
