pardon o soruyu kaçırmış olmalıyım. aynı sürede deforme olmaz elbette. bir firma ürettiği mal hakkında a süresi koyuyorsa, onu bazı istatistiklere dayandırır. örneğin bu konuda olduğu gibi 5 sene süresi, farzı misal 4000 saatlik sürüş için geçerlidir(süreyi bilmiyorum tam olarak). bu demek oluyor ki ekstrem durumlar söz konusu ise deforme süresi kısalır veya ürün kullanılmıyorsa yine deforme olur ama belki 8 sene sürer.
aklında soru işaretleri kalanlara için de:
" First, did you know Arai helmets were the first to carry a full five-year warranty? "
"Snell recommends that a helmet be replaced within five years from its date of first use, and no more than seven years from its date of manufacture."
"The simple truth is, even a helmet as good as an Arai won’t last forever.
Why? Think of a helmet in terms of your body. No matter how good it may look, or how well you take care of it, age takes its toll. Even with minimal use, a helmet is affected by things like acids and oils in sweat, hair care products, pollution, exposure to UV rays, etc. At about the five-year mark, helmet interiors begin to show normal wear, which should serve as an alert to its overall condition. The helmet’s fit may begin to feel a little “loose,” not as snug as it once did. This unseen, but normal, aging of the EPS liner and fiberglass shell can affect the helmet’s ability to perform in an impact as it was originally designed to do."
