Plastikai. Praskiestų polimerų tirpalų klampos nustatymas kapiliariniais viskozimetrais. 2 dalis. Polivinilchloridinės dervos (ISO/DIS 1628-2:2026)

1.1 This document specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins can contain small amounts of unpolymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the polymerization. This document is not applicable, however, to resins having a volatile-matter content in excess of 0,5 % ± 0,1 %, when determined in accordance with ISO 1269:2006. In addition to this, it is not applicable to resins which are not entirely soluble in cyclohexanone. 1.2 The reduced viscosity and K-value of a particular resin are related to its molecular mass, but the relationship varies depending on the concentration and type(s) of other monomer(s) present. Hence, homopolymers and copolymers having the same reduced viscosity or K-value can have different molecular masses. 1.3 The values determined for reduced viscosity and K-value, for a particular sample of PVC resin, are influenced differently by the concentration of the solution chosen for the determination. Hence the use of the procedures specified in this document only gives values for reduced viscosity and K-value that are comparable when the concentrations of the solutions used are identical. 1.4 The experimental procedures specified in this document can also be used to characterize the polymeric fraction obtained during the chemical analysis of a PVC composition. However, the values calculated for the reduced viscosity and K-value in these circumstances can deviate form the correct values for the resin used to produce the composition because of the impure nature of the recovered polymer fraction.

Neardomieji bandymai. Pramoninė kompiuterinė radiografija naudojant fosforo vaizdo plokštes. 1 dalis. Sistemų klasifikavimas

This document specifies fundamental parameters of computed radiography (CR) systems with the aim of enabling satisfactory and repeatable results to be obtained economically. The techniques are based both on fundamental theory and test measurements. This document specifies the performance of CR systems and the measurement of the corresponding parameters for the system scanner and storage phosphor imaging plate (IP). CR system classes are defined in combination with specified metal screens for industrial radiography. This document ensures that the quality of the images, as far as they are influenced by the scanner IP system, complies with the requirements of ISO 16371-2. This document considers the requirements for film radiography specified in ISO 11699-1. This document specifies system tests at different levels. More complex manufacturer tests are described, which allow the determination of precise system parameters to characterize the performance of CR systems from different suppliers and make them comparable for users. Simpler tests are also described, which are designed for fast tests of the quality of CR systems and long-term stability monitoring by the user.
