生理食塩水溶解率は、例えば、次のようにして測定される。すなわち、先ず、無機繊維を200メッシュ以下に粉砕して調製された試料1g及び生理食塩水150mLを三角フラスコ(容積300mL)に入れ、40℃のインキュベーターに設置する。次に、三角フラスコに、毎分120回転の水平振動を50時間継続して加える。その後、ろ過により得られた濾液に含有されている各元素の濃度(mg/L)をICP発光分析装置により測定する。そして、測定された各元素の濃度と、溶解前の無機繊維における各元素の含有量(質量%)と、に基づいて、生理食塩水溶解率(%)を算出する。すなわち、例えば、測定元素が、ケイ素(Si)、マグネシウム(Mg)、カルシウム(Ca)及びアルミニウム(Al)である場合には、次の式により、生理食塩水溶解率C(%)を算出する;C(%)=[ろ液量(L)×(a1+a2+a3+a4)×100]/[溶解前の無機繊維の質量(mg)×(b1+b2+b3+b4)/100]。この式において、a1、a2、a3及びa4は、それぞれ測定されたケイ素、マグネシウム、カルシウム及びアルミニウムの濃度(mg/L)であり、b1、b2、b3及びb4は、それぞれ溶解前の無機繊維におけるケイ素、マグネシウム、カルシウム及びアルミニウムの含有量(質量%)である。
