This Standard Reference Material (SRM) is intended primarily for use in evaluating analytical methods used for the determination of selected major, minor, and trace elements in bone and in material of a similar matrix. It consists of steamed bone meal that was sieved and blended to a high degree of homogeneity. A unit of SRM 1486 consists of approximately 50 g of bone meal.

Certified Mass Fraction Values: Certified mass fraction values for constituent elements on a dry-mass basis, are provided in Table 1. A NIST certified value is a value for which NIST has the highest confidence in its accuracy in that all known or suspected sources of bias have been investigated or taken into account [1]. The measurands are the total concentrations of the elements

本标准参考物质（SRM）主要用于评估用于测定骨骼和类似基质材料中选定的主要、次要和微量元素的分析方法。它由经过筛分并混合到高度均匀的蒸骨粉组成。SRM 1486的一个单元由大约50g的骨粉组成。 美国NIST- SRM 1486

认证质量分数值：表1中提供了干质量基础上组成元素的认证质量分数。NIST认证值是指NIST对其准确性具有最高信心的值，因为所有已知或怀疑的偏差源都已被调查或考虑[1]。被测物是元素的总浓度 可追溯标准物质骨粉
