High-visibility clothing with the EN ISO 20471:2013 rating is tested for its ability to visually signal the wearer's presence in all light conditions, including daylight and vehicle headlights in the dark. This ensures the clothing makes you clearly visible to others, significantly reducing the risk of accidents in hazardous environments.

PPE stands for "personal protective equipment." PPE Category 2 refers to equipment that is more complex, and has a higher level of risk. Examples of PPE Category 2 include safety helmets, ear protection, and fall arrest equipment. In Europe, PPE Category 2 must meet certain safety standards set by the European Union, which means that it must be designed and manufactured to protect the user without causing harm. Companies that make or sell PPE must prove that it meets these standards. They also must have a quality management system in place and have to be audited regularly by a notified body.
