1.    I've heard Auralex products are "Class B." What does that mean?

聽說Auralex產品防火等級是B級,是什麼意思?

The Standard for Surface Burning (ASTM E84 or NFPA 255) yields two numbers: "Flame Spread Index" and "Smoke Developed Index" These numbers are compared with three ranges called out in building and fire safety codes. The three ranges correspond to "Class A", "Class B", and "Class C." (Some codes refer to these as "Class 1", "Class 2", and "Class 3." The Class designations are interchangeable.) 

表面燃燒標準(ASTM E84 or NFPA 255)用兩個數字來表示:火焰散播指數及煙霧發展指數;這些數字和美國建築與消防安全法規標準對照,可以被分為A,B,C三級。 

Depending on the results of the test, a material will fall into one of these three categories. "Class A" (or "Class 1") is the best, indicating that a material is not likely to burn very much, but may produce some smoke. "Class C" (or "Class 3") is the worst, indicating that a material will likely burn more and possibly even produce more smoke. 

依據測驗結果,各材質會被分為3類, A級最好,表示材質不太會燒起來,可能產生一些煙;C級最差,表示材質會燒起來,且可能產生很多煙。

All Auralex acoustical foam products are "Class B." Without getting too technical, it means that Auralex acoustical foam products will burn a little more than a "Class A" material and will produce smoke.

所有Auralex acoustical foam 吸音綿產品都是B級,簡單的說:比起A級,材質比較容易燒,煙比A級多一點 

Note that all "Classes" of foam are considered "fire retardant." The types of foam to be extremely wary of are those that have no "Class" designation at all. In all likelihood, these materials have no fire retardant properties whatsoever and Auralex discourages their use as acoustical treatments.

請顧客們注意:所有等級都防燃,要耽心的是:未標示防燃等級的產品,未標示防燃等級的產品不適合做室內聲音處理的工具

 

  So does "Class B" meet my building codes?

B級符合我們的建築法規標準?

It depends. Unfortunately, building codes vary widely from place to place. There is no "nationwide" building or fire safety code that everyone follows. Literally, something considered acceptable for your building may not be considered acceptable for the same type of building in a town, say, four miles from you. If you are unsure at all about what is or is not acceptable for your building, you are strongly encouraged to contact your local fire marshal, fire inspector, or building inspector prior to purchasing any acoustical treatment products.  

這要看。不幸的是,各地方的建築規範差別甚大,沒有全國公認的建築或消防安全守則,從字面解釋上看,有些人認為可以接受,在同一個城市裡,同一類型的建築,可能有些人認為是不可以接受。購買任何聲學處理的產品之前,如果您不確定是否能符合當地的建築或消防法規,建議您聯繫當地的建築管理單位、消防官員,取得,督察或建設之前,取得確定符合當地建築或消防法規的認知。
