Nuosėdos, dirvožemis, dumblas ir atliekos. Perfluoralkilų ir polifluoralkilų grupes turinčių cheminių medžiagų (PFAS) analizė efektyviosios skysčių chromatografijos ir masių spektrometrijos metodu (ISO/DIS 25652:2025)

This document specifies a method for quantitative determination of various perfluorinated hydrocarbons by means of High-Performance Liquid Chromatography (HPLC) and mass spectrometry in soil, sludge, sediment and waste (see Table 1). For many substances to which this document applies a limit of quantification (LOQ) of 0.1 to 10 μg/kgdm can be achieved. The method can be applied to the analysis of additional PFAS not specified in the scope, if validity is proven by proper in-house validation protocols. For each target compound both, eventually occurring branched, isomers and the respective non-branched isomer are quantified together. In this method the amount of linear and branched PFAS is quantified using the response factor of the linear PFAS in the calibration standard and the total area of the linear and branched PFAS (Annex 1 gives more explanation)

Biotechnologija. Biobankai. Bendrieji reikalavimai biobankams (ISO/DIS 20387:2025)

This document specifies general requirements for the competence, impartiality and consistent operation of biobanks including quality control requirements to ensure that collections of biological material and associated data are of appropriate quality. This document is applicable to all organizations performing biobanking. This can include biobanking of biological material: a) from multicellular organisms (e.g. human, animal, fungus and plant); b) from microorganisms; c) derived from sources such as environmental samples (e.g. soil, sediment, water, air). Biobank users, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others can also use this document in confirming or recognizing the competence of biobanks. This document does not apply to biological material intended for therapeutic use. NOTE 1 International, national or regional regulations or requirements can also apply to specific topics covered in this document. NOTE 2 For entities handling human materials procured and used for diagnostic and treatment purposes, ISO 15189 and other clinical standards are intended to apply first and foremost.

Metalinės medžiagos. Charpy smūginio tąsumo bandymas. 3 dalis. Sertifikuotų pamatinių Charpy bandinių su V įpjova, skirtų švytuokliniams muštuvams netiesiogiai patikrinti, paruošimas ir apibūdinimas (ISO/DIS 148-3:2025)

ISO 148-3:2016 specifies the requirements, preparation and methods for qualifying test pieces used for the indirect verification of pendulum impact testing machines in accordance with ISO 148‑2. It specifies notched test pieces with nominal dimensions identical to those specified in ISO 148‑1; however, the tolerances are more stringent. NOTE 1 The chemical composition or heat treatment, or both, are varied according to the energy level desired. NOTE 2 Reference test pieces are qualified on reference pendulum impact testing machines which are also described in this part of ISO 148.

Metalinės medžiagos. Charpy smūginio tąsumo bandymas. 2 dalis. Bandymo mašinų patikra (ISO/DIS 148-2:2025)

ISO 148-2:2016 covers the verification of pendulum-type impact testing machines, in terms of their constructional elements, their overall performance and the accuracy of the results they produce. It is applicable to machines with 2 mm or 8 mm strikers used for pendulum impact tests carried out, for instance, in accordance with ISO 148‑1. It can be applied to pendulum impact testing machines of various capacities and of different design. Impact machines used for industrial, general or research laboratory testing of metallic materials in accordance with this part of ISO 148 are referred to as industrial machines. Those with more stringent requirements are referred to as reference machines. Specifications for the verification of reference machines are found in ISO 148‑3. ISO 148-2:2016 describes two methods of verification. a) The direct method, which is static in nature, involves measurement of the critical parts of the machine to ensure that it meets the requirements of this part of ISO 148. Instruments used for the verification and calibration are traceable to national or international standards. b) The indirect method, which is dynamic in nature, uses reference test pieces to verify points on the measuring scale for absorbed energy. The requirements for the reference test pieces are found in ISO 148‑3. A pendulum impact testing machine is not in compliance with this part of ISO 148 until it has been verified by both the direct and indirect methods and meets the requirements of Clause 6 and Clause 7. ISO 148-2:2016 describes how to assess the different components of the total energy absorbed in fracturing a test piece. This total absorbed energy consists of - the energy needed to fracture the test piece itself, and - the internal energy losses of the pendulum impact testing machine performing the first half-cycle swing from the initial position. NOTE Internal energy losses are due to the following: - air resistance, friction of the bearings of the rotation axis and of the indicating pointer of the pendulum which can be determined by the direct method (see 6.4.5); - shock of the foundation, vibration of the frame and pendulum for which no suitable measuring methods and apparatus have been developed.

Metalinės medžiagos. Charpy smūginio tąsumo bandymas. 1 dalis. Bandymo metodas (ISO/DIS 148-1:2025)

ISO 148-1:2016 specifies the Charpy (V-notch and U-notch) pendulum impact test method for determining the energy absorbed in an impact test of metallic materials. This part of ISO 148 does not cover instrumented impact testing, which is specified in ISO 14556. Annexes B and C are based on ASTM E23 and are used with the permission of ASTM International, 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959, USA.
