Neardomieji bandymai. Radiografinių plėvelių skaitmeninio apdorojimo sistemų įvertinimas. 1 dalis. Apibrėžtys, kiekybiniai vaizdo kokybės parametrų matavimai, etaloninė pamatinė plėvelė ir kokybės kontrolė (ISO/DIS 14096-1:2025)

This document specifies procedures for the evaluation of basic performance parameters of the radiographic film digitisation process such as spatial resolution and spatial linearity, density range, density contrast sensitivity and characteristic transfer curve. They can be integrated into the system software and together with a standard reference film (see Annex B) used for quality control of the digitisation process. This reference film provides a series of test targets for performance evaluation. The test targets are suitable for evaluating a digitisation system with a basic spatial resolution down to 10 µm, a density contrast sensitivity down to 0,02 optical density, a density range of 0,5 to 4,5 and a film size capacity of (350∙430) mm2. This document does not address signal processing and display of the digitised data.

Neardomieji bandymai. Radiografinių plėvelių skaitmeninio apdorojimo sistemų įvertinimas. 2 dalis. Mažiausieji reikalavimai (ISO/DIS 14096-2:2025)

This document specifies three film-digitisation quality classes for the requirements of non-destructive testing. The selected class depends on the radiation energy, the material thickness penetrated and the quality level of the original radiographic film. This document does not address signal processing, display and storage of the digitised data.

Neardomieji bandymai. Bandymai akustine spinduliuote. Pluoštu armuotų polimerų tyrimų specialioji metodika ir bendrieji įvertinimo kriterijai (ISO 18249:2015)

This International Standard describes the general principles of acoustic emission testing (AT) of materials, components, and structures made of fibre-reinforced polymers (FRP) with the aim of — materials characterization, — proof testing and manufacturing quality control, — retesting and in-service testing, and — health monitoring. This International Standard has been designed to describe specific methodology to assess the integrity of fibre-reinforced polymers (FRP), components, or structures or to identify critical zones of high damage accumulation or damage growth under load (e.g. suitable instrumentation, typical sensor arrangements, and location procedures). It also describes available, generally applicable evaluation criteria for AT of FRP and outlines procedures for establishing such evaluation criteria in case they are lacking. This International Standard also presents formats for the presentation of acoustic emission test data that allows the application of qualitative evaluation criteria, both online during testing and by post-test analysis, and that simplify comparison of acoustic emission test results obtained from different test sites and organizations. NOTE The structural significance of the acoustic emission cannot in all cases definitely be assessed based on AT evaluation criteria only but can require further testing and assessment (e.g. with other non-destructive test methods or fracture mechanics calculations).
