If you’ve ever shopped for new windows and suddenly found yourself staring at random letter-number codes like ASTM F588, ASTM F842, or EN 1627 WK2, you’re not alone. Most homeowners see these labels and instantly wonder what they actually mean. That’s a very common reaction. But here’s the thing: these standards actually tell you how safe, secure, and durable your windows really are. And depending on whether you’re looking at American standards (ASTM) or European standards (EN 1627), the testing, expectations, and performance levels are surprisingly different.

Most of us think about windows in terms of looks — the style, the view, the light — but very few people think about how safe they actually are. Your windows might be letting in the sun just fine, but if they’re easy to open from the outside, they’re not doing much to keep your home safe. That’s where European security standards come in. You’ve probably seen terms like Basic, WK1, and WK2 floating around and wondered what they really mean. Don’t worry — you’re not alone. Let’s break it down in plain, friendly language, so you know exactly what each level of protection means for your home.
