This document specifies a field method for the assessment of the surface density of various water-soluble salts on steel surfaces, before and/or after surface preparation, by conductometric determination. The individual surface densities of the salt composition like chlorides, sulphates, sodium, etc, cannot be determined by this method. This method assesses only contaminants that forms an electrolyte (ions) when in contact with water. These represent the greater part of the contaminants.

This document establishes general principles for the execution of soil treatment by deep vibration. The following types of treatment are covered by this document: - deep vibratory compaction to densify the ground as mentioned in EN 1997 3:2025, Annex I, Table I.1; - vibrated columns formed by inserted granular material laterally/radially compacted against the surrounding ground to form a stiff composite column-soil structure (vibrated compacted granular columns) as mentioned in EN 1997 3:2025, Annex I, Table I.2; - vibrated columns formed by inserted material developing unconfined compressive strength comprising a composite of binder and granular material (rigid columns) as mentioned in EN 1997 3:2025, Annex I, Table I.2. The following treatment methods are covered by this document: - methods in which depth vibrators, containing oscillating weights which cause horizontal vibrations, are inserted into the ground; - methods in which compaction probes are inserted into the ground using a vibrator, which remains above ground surface, and which oscillates in a vertical mode. Treatment methods are outlined in Annexes A, B, C and D. The following treatment methods, among others, are not included in this document: - dynamic compaction, dynamic replacement and other methods in which some form of treatment is applied to the ground surface; - uncompacted granular columns primarily used as drains; - explosive compaction.

Plieninio pagrindo paruošimas prieš dengiant dažais ir su jais susijusiais produktais. Srautinio valymo būdu paruošto plieninio pagrindo šiurkštumo charakteristikos. 5 dalis. Kopijavimo juostos metodas paviršiaus profiliui nustatyt (ISO/DIS 8503‑5:2026)

ISO 8503-5:2017 describes a field method for measuring the surface profile produced by any of the abrasive blast-cleaning procedures given in ISO 8504-2. The method uses replica tape and a suitable gauge for measuring, on site, the roughness of a surface before the application of paint or another protective coating. The method is applicable within the range of profile heights cited for a given grade (or thickness) of replica tape. The commercial grades currently available permit measurement of average peak-to-valley profiles of 20 µm to 115 µm. The method is valid for surfaces that have been cleaned with abrasives.
