Naftos ir dujų pramonė, įskaitant mažesnio anglies dioksido pėdsako energijos gamybą. Viso žiedo ovalėjimo bandymo metodas plieninių vamzdynų atsparumui pleišėjimui rūgštinėje aplinkoje įvertinti (ISO 3845:2024)

This document gives a method for determining the resistance to cracking of steel pipes in sour service. This test method employs a full-scale test specimen consisting of a short length of pipe (a ‘full ring’), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes. NOTE 1 The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above. NOTE 2 This test method can also be used for corrosion resistant alloys (CRAs). The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen. The test specimen is then subjected to single sided exposure to the sour test environment. NOTE 3 The test also allows measurement of hydrogen permeation rates.

This calculation module applies to instantaneous domestic hot water heat recovery using a counter-flow heat exchanger between the drain water and the incoming domestic cold water. This module calculates the recovered heat, to be taken into account in the overall calculation procedure of the energy performance of the building. The scope of this document is to standardize the: - required inputs; - calculation methods; - required outputs; of the instantaneous heat recovery from domestic hot water drains. This document provides a calculation method for one calculation interval. This calculation is intended to be connected to the whole building calculation model and takes into account the external conditions and system controls that may influence the instantaneous heat recovery from domestic hot water drains. This document does not apply to storage heat recovery or the use of drain water as a source for heat pumps. This document does not apply to sizing or inspection of domestic hot water heat recovery devices.

Vandens kokybė. Žarninių lazdelių (Escherichia coli) ir koliforminių bakterijų skaičiavimas. 4 dalis. Žarninėms lazdelėms (Escherichia coli) taikomas membraninio filtravimo metodas, skirtas vandeniui, kuriame yra didelis foninių bakterijų kiekis

This document describes a highly specific method for the enumeration of Escherichia coli (E. coli) in water. The method is based on membrane filtration followed by culture at 44 °C on chromogenic agar medium containing an ingredient for the detection of the enzyme β-glucuronidase, and calculation of the number of target organisms in the sample[5,6,13]. Because of the high specificity of the method, this document is suitable for waters with high levels of background bacteria, such as surface waters including bathing water and wastewater provided that they contain little particulate or colloidal matter relative to the E. coli concentration. The method can be used for fresh water and, with an adaptation, for marine water. E. coli strains which do not grow at 44 °C and those that are β-glucuronidase negative, such as E. coli O157, will not be detected as E. coli by this method. This method is not applicable to the enumeration and detection of coliform bacteria other than E. coli.

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.

This document specifies a method for the selective enumeration of bifidobacteria in milk products by using a colony-count technique at 37 °C under anaerobic conditions. The method is applicable to milk products, such as fermented (e.g. yoghurts) and non-fermented milks (e.g. pasteurized milks, skim milks, whey protein concentrates), milk powders and formulae (e.g. infant formulae, follow-up formulae for older infants, products for young children) where these microorganisms are present and viable, in combination with other lactic acid bacteria or alone. The method is also applicable to starter and probiotic cultures. For proposed quality criteria of dairy products, see, for example, CXS 243-2003. Bifidobacteria used in milk products usually belong to the following species (e.g. References [7] and [10]): — Bifidobacterium adolescentis; — B. animalis subsp. animalis; — B. animalis subsp. lactis; — B. bifidum; — B. breve; — B. longum subsp. infantis; — B. longum subsp. longum.
