A standard reference 10 sample-set of fibrous minerals were prepared by the Japan Fibrous Material Research Association (JFMRA) under the name of JMF standard reference samples. In this paper, the fiber number per unit weight of JFM standard reference samples was determined with a scanning electron microscope. Fiber numbers per unit weight (f/microgram) and standard deviations observed in this experiment were as follows: glass wool (GW1) 7.0 +/- 0.1 x 10(2), rock wool (RW1) 1.7 +/- 0.2 x 10(3), micro glass fiber (MG1) 6.5 +/- 0.4 x 10(4), refractory ceramic fibers; (RF1) 8.8 +/- 0.7 x 10(3), (RF2) 8.7 +/- 0.8 x 10(3), mullite fibers (RF3) 3.5 +/- 0.7 x 10(3), potassium titanate whisker (PT1) 5.9 +/- 0.3 x 10(5), silicon carbide whisker (SC1) 4.1 +/- 0.4 x 10(5), titanium oxide whisker (rutile) (TO1) 6.4 +/- 0.6 x 10(5), and wollastonite (WO1) 2.4 +/- 0.1 x 10(4). Fiber numbers per unit weight would change in proportion to the cube or cube root of the fiber size if the fibers have the same density and the same aspect ratio. JFM standard reference samples should be used taking into consideration the difference in fiber number per unit weight when users conduct in vitro and/or in vivo (injection) biological experiments using these samples.
日本纤维材料研究协会（JFMRA）制备了一组标准参考用的10种纤维状矿物样本，命名为JMF标准参考样本。在本文中，使用扫描电子显微镜测定了JFM标准参考样本的单位重量纤维数量。本次实验中观察到的单位重量纤维数量（每微克纤维数量）及标准偏差如下：玻璃棉（GW1）7.0±0.1×10²，岩棉（RW1）1.7±0.2×10³，微玻璃纤维（MG1）6.5±0.4×10⁴，耐火陶瓷纤维；（RF1）8.8±0.7×10³，（RF2）8.7±0.8×10³，莫来石纤维（RF3）3.5±0.7×10³，钛酸钾晶须（PT1）5.9±0.3×10⁵，碳化硅晶须（SC1）4.1±0.4×10⁵，氧化钛晶须（金红石）（TO1）6.4±0.6×10⁵，以及硅灰石（WO1）2.4±0.1×10⁴。如果纤维具有相同的密度和相同的长径比，单位重量纤维数量将与纤维尺寸的立方或立方根成比例变化。当使用者使用这些样本进行体外和/或体内（注射）生物实验时，应考虑单位重量纤维数量的差异来使用JFM标准参考样本。
