GOST R 58144-2018 «Distilled water. Specifications» became the most popular document according to the information received from the Department of Distribution of the Documents on Standardization of FSBI «RST». This standard has become effective since July 2021.
National standard is distributed on the distilled water received by the unit for water treatment. This distilled water also can be applied as a solvent for preparation of solutions of substances, chemicals, reagents while testing in technological operations and processes.
This document contains requirements for the distilled water: its specific appearance, smell and other physico-chemical parameters.
Series of standards on concretes attracted interest among the customers. These documents are the following: GOST R 18105-2018 «Concretes. Rules for control and assessment of strength», GOST 12730.2-2020 «Concretes. Method of determination of moisture content», GOST 12730.1-2020 «Concretes. Methods of determination of density», GOST 12730.3-2020 «Concretes. Method of determination of water absorption», GOST 12730.0-2020 «Concretes. General requirements for methods of determination of density, moisture content, water absorption, porosity and water tightness». GOST R 18105-2018 «Concretes. Rules for control and assessment of strength» became effective in 2020 while other above-mentioned documents came into force in 2021.
GOST 12730.2-2020 «Concretes. Method of determination of moisture content» covers the concretes of all types and sets the method of determination of moisture content by testing of the samples.
GOST 12730.1-2020 «Concretes. Methods of determination of density» is distributed on all types of concretes and sets the methods of determination of true and average density of concretes by testing of the samples.
GOST 12730.3-2020 «Concretes. Method of determination of water absorption» is applicable to the concretes of all types and sets the methods of determination of water absorption by testing of the samples.
GOST 12730.0-2020 «Concretes. General requirements for methods of determination of density, moisture content, water absorption, porosity and water tightness» unites all the above-mentioned standards. It is applied to concretes of all types which are used in industrial, energetic, transport, hydrotechnical, agricultural, residential, civil construction and other types of construction.
GOST R 18105-2018 «Concretes. Rules for control and assessment of strength» is distributed on all types of concretes for which strength is normalized. This standard establishes the rules for control and evaluation of strength of concretes during quality control of concrete mixtures, concrete and reinforced concrete products, constructions including monolithic and prefabricated monolithic constructions.
