  Mechanical Strength B

  EN 166:1995 defines the criteria for personal eye protection in terms of mechanical strength and durability, with the 'Mechanical Strength B' designation indicating that the eyewear is capable of withstanding medium energy impact. This classification specifically means the eyewear can resist a 6 mm, 0.86 g ball traveling at 120 meters per second. The test for this involves firing the specified ball at the lens and frame of the eyewear to ensure that it can protect against such impacts without breaking or dislodging. This level of performance is particularly relevant for safety glasses used in environments such as construction sites, workshops, and laboratories, where there is a risk of flying particles and moderate impact hazards. Eyewear meeting the 'B' standard provides essential eye protection, ensuring that users are safeguarded against a significant range of impact-related injuries.

• EN 170:1986

  EN 170:1986 is a European standard that defines the requirements and test methods for the performance of smoke control systems in buildings. The standard specifies the minimum levels of performance that the system must meet, as well as the methods that should be used to test the system to ensure it meets these requirements. Possible test results include the ability of the system to control the spread of smoke, the airflow rate and pressure drop of the system, and the resistance to fire spread.
