DIN 7080 Standard for Glass Quality
Metaglas sight glasses use glass that meets the DIN 7080 standard, which means our glass has passed tests for material strength, shock endurance, chemical resistance and compression. Because competing products are made of soda lime glass, they do not meet DIN 7080.
