前陣子發了個帖講述我自己的catlike vacuum頭盔重生經歷 被幾位車友指出頭盔壽命有限 需要定期換新
但作爲屌絲的我 相信可以代表一部分車友的 "好不容易攢了頂不錯的頭盔壞都沒壞就扔了實在可惜" 的心態
而且我也在交易區看到過出售很久以前頭盔的案例
所以希望集羣衆的力量 看看頭盔這個關鍵時候保命的玩意兒 它的使用壽命到底應該是多少 (搜過了本站貌似沒有權威的講法)
爲此我也去幾家頭盔廠商的網站晃了一圈 公司網絡比較爛 以下是我能找到的結果 (LZ大概翻譯了一下) 歡迎補充
Giro的FAQQ: How often should a helmet bereplaced? 頭盔應該多久換一次?Girohas a general recommendation of replacing your helmet every three (3) years.Giro建議每3年把你的頭盔換新. (順帶一些存放保養建議)Q: How do I store my helmet? 頭盔怎麼存放?Aftereach use, allow the helmet to air dry and then store it in a cool, dry placewhere it won’t get damaged.Notethat excessive heat can damage your helmet. For example, in direct sunlight adark gear bag, the interior of a car, or an automobile trunk can get hot enoughto cause heat damage (damaged helmets will appear to have uneven or bubblysurfaces). Therefore, when not being used for a period of time we recommendthat the helmet be placed back into its box or case and stored in a cool, dryplace.每次使用後, 讓頭盔自然風乾然後存放在陰涼乾燥不會受傷的地方. 注意過熱會損傷你的頭盔. 比如,放在深色包裏, 汽車內籠或後備箱接受陽光直射會積聚足夠的熱量導致熱損傷(受損的頭盔看上去不平整或有鼓包).所以, 如果一段時間不用的話, 我們建議把頭盔放回它包裝盒(早扔了...)然後存放在陰涼乾燥的地方.Q: How do I take care of my helmet? 頭盔怎麼保養?CleaningYour Helmet 清洗頭盔
Helmets are made of materials that can be damaged by many commonly availablecleaners. Petroleum based solvents or cleaners are especially dangerous. Theycan damage a helmet so that its protective capabilities are significantlyreduced. Many times this damage is not visible. For best results, clean thehelmet using a soft cloth or sponge, warm water and mild soap (such as a milddish soap).製造頭盔的材料很容易被日常洗劑損傷. 石化溶劑或洗劑尤其危險. 它們能讓頭盔的保護能力嚴重下降. 很多時候這種損傷是不可見的. 爲此,請使用軟布或海綿, 配合溫水和中性肥皂清洗頭盔. 閃電的更詳細 搬出了SMF(Snell Memorial Foundation - 米國專門研究頭盔安全性的非營利機構)的權威建議Howlong should a bicycle helmet last? 自行車頭盔的壽命該是多少?Last Updated: Aug 23, 2013 09:59AM PDTSpecialized follows the recommendationsof the Snell Memorial Foundation that helmets should be replaced five yearsafter the date of purchase http://www.smf.org/helmetfaq#aWhyReplace
S家遵從SMF的建議, 頭盔應該在購買後5年內換新.Whyshould you replace your helmet every five years? 爲毛你要5年換一次頭盔?The five-year replacementrecommendation is based on a consensus by both helmet manufacturers and theSnell Foundation. Glues, resins and other materials used in helmet productioncan affect liner materials. Hair oils, body fluids and cosmetics, as well asnormal "wear and tear" all contribute to helmet degradation.Petroleum based products present in cleaners, paints, fuels and other commonlyencountered materials may also degrade materials used in many helmets possiblydegrading performance. Additionally, experience indicates there will be anoticeable improvement in the protective characteristic of helmets over afive-year period due to advances in materials, designs, production methods andthe standards. Thus, the recommendation for five-year helmet replacement is ajudgment call stemming from a prudent safety philosophy."
5年一換的建議是基於頭盔廠商與SMF的共識. 膠水, 塑膠和其它用於頭盔生產的材料會影響內襯材料. 頭油, 體液和化妝品, 以及普通的穿脫都會推動頭盔的降解.清潔劑, 塗料, 燃料和其它平時接觸的石化產品也會導致許多頭盔中實用的材料發生降解,從而可能導致性能減退. 另外, 經驗指出隨着材料, 涉及, 生產方式和標準的進步,頭盔的保護性能每5年都會有顯著的提升. 因此, 5年一換的建議是基於審慎安全的理念作出的判斷.
A helmet needs to be replaced after any crash where something comes in contactwith your head. If you are the lucky one that never crashes, then we wouldstill recommend replacing your helmet after 5 years of use.
頭盔需要在任何與頭部發生接觸的事故後更換. 如果你運氣好到從不摔/撞車, 那我們仍然建議5年把你的頭盔換新.
A helmet is a key item to your safety and we strongly recommend that youconsistently examine your helmet for any cracks and replace it as often asneeded.
頭盔是安全的關鍵裝備, 我們牆裂建議你時不時地檢查你的頭盔是否有裂縫並且該換就換.
