This document describes procedures for the determination of non-rare earth impurities in individual rare earth metals and their oxides through the use of inductively coupled plasma atomic emission spectroscopy (ICP-AES). Magnesium (Mg), aluminum (Al), silicon (Si), calcium (Ca) and iron (Fe) are included as non-rare earth impurity elements, and the measurement ranges for each impurity element are specified. The applicable measurement range (mass fraction %) of magnesium, aluminum, silicon and calcium is from 0,001 to 0,2, and that of iron is from 0,001 to 0,5. The verified measurement ranges in the interlaboratory tests are described later in this document.

This European Standard specifies a method to determine the macroscopic impurities > 2 mm and stones > 5 mm in compost and digestate. Macroscopic impurities are contaminants not naturally occurring in soil such as pieces of glass, metal, plastics, rubber, cigarette buds etc.) This method is not able to make a distinction between compostable and non-compostable plastics. Fragments of wood or bark are acceptable constituents of the sample and not classified as macroscopic impurities.

Guidance and methods for activity measurements of materials to be released for recycling, re-use or disposal as non-radioactive waste arising from the operation of nuclear facilities.

This document covers the determination of the characteristic load resistance Fp and the characteristic plate stiffness kp of plate anchors.
