Organinės ir organinės-mineralinės trąšos. Tam tikrų elementų visuminio kiekio nustatymas po skaidymo karališkuoju vandeniu atliekant induktyviai susietos plazmos atominę emisinę spektroskopiją (ICP-AES)

This document specifies a method for the determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni)), boron (B), cobalt (Co), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sulfur (S) and sodium (Na) in aqua regia digests of organic, organo-mineral fertilizers, and their fertilizing product blends using inductively coupled plasma-atomic emission spectrometry (ICP-AES). It is applicable and validated for several types of matrices as indicated in Annex A. This document is applicable to the component materials “by-products”, when used as components of fertilizing products, as well as the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible. This method is applicable to aqua regia digests prepared according to prEN 17768. NOTE Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the determination of the elements in the aqua regia digests if the user proves that the method gives the same results.

Kelių ir aerodromų dangų paviršiaus charakteristikos. Bandymo metodai. 4 dalis. Paviršiaus atsparumo slydimui matavimo metodas. Bandymas švytuokle

This document describes a method for determining the slip/skid resistance of a surface using a device which remains stationary at the test location. The slip/skid resistance is measured by means of a slider mounted at the end of a pendulum arm. The method provides a measure of the slip/skid resistance properties of a wetted surface either in the field or in the laboratory. This method measures the slip/skid resistance of a small area of a surface (approximately 0,01 m2). It is important to consider this when deciding its applicability to a surface which might have nonhomogeneous surface characteristics, e.g. containing ridges or grooves, or is rough textured (exceeding 1,5 mm mean texture depth).
