This document specifies requirements and gives recommendations for 8 classes of well cements, including their chemical and physical requirements and procedures for physical testing. This part of ISO 10426 is applicable to well cement classes A, B, C and D, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of class D cement. This part of ISO 10426 is also applicable to well cement classes G and H, which are the products obtained by grinding clinker with no additives other than one or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction. This part of ISO 10426 is also applicable to composite well cements classes K and L, which are the products obtained by intergrinding Portland cement clinker and one or more forms of CaSO4 with specified composite constituents, or by subsequent blending of separately produced Portland cement with separately processed specified composite constituents. This document is a supplement to API Spec 10A 25th edition (2019) and its Addendum 1 (November 2019) and Addendum 2 (August 2022), the requirements of which are applicable with the exceptions specified in this document.

This document specifies requirements and test methods for marketed and delivered automotive B10 diesel fuel, i.e. diesel fuel containing up to 10,0 %(V/V) fatty acid methyl ester (FAME). It is applicable to fuel for use in diesel engine vehicles compatible with automotive B10 diesel fuel. NOTE 1 This product is allowed in Europe [4], but national legislation can set additional requirements or rules concerning, or even prohibiting, marketing or delivering of the product. NOTE 2 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.

This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear. From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus. This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

This document specifies the Binder Fast Characterization Test (for short: BTSV test, German: Bitumen-Typisierungs-Schnell-Verfahren). The test is conducted using a Dynamic Shear Rheometer (DSR). It is used to characterize bitumen and bituminous binders and to assess the deformation behaviour at high service temperatures. The test procedure described in this document covers the testing of paving grade bitumen or modified bitumen, as fresh (unused) binders, as well as binders after laboratory ageing conditioning (e.g. EN 12607-1, EN 14769), and also binders that have been recovered from asphalt mixtures. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). NOTE The test procedure has not been applied on bituminous binders recovered from bitumen emulsions yet. The test determines the temperature and the associated phase angle at which a bituminous binder exhibits a defined complex shear modulus in stress-controlled oscillation mode at constant frequency and with continuous increase of the test temperature. WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to ensure that regulatory requirements are fulfilled prior to application of this document. This document involves handling of apparatus and binders at very high temperatures. Always wear protective gloves and eyewear when handling hot binders, and avoid contact with any exposed, unprotected skin.

This document provides testing procedures for evaluating proppants used in hydraulic fracturing and gravel packing operations. NOTE Proppants mentioned in this document refer to sand, ceramic, resin-coated, gravel packing proppants, and other materials used for hydraulic fracturing and gravel packing operations. This document supplements API RP 19D, 2nd edition (2021), the requirements of which are applicable with the exceptions specified in this document. This document provides consistent methodology for testing performed on hydraulic fracturing and/or gravel packing proppants. It is not intended for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions.

This document specifies requirements for surface preparation, materials, application, inspection and testing of internal coating lining systems that are intended to be applied on internal surfaces of steel storage tanks of crude oil, hydrocarbons and water for corrosion protection. It covers both new construction and maintenance works of tank internal coating and lining as well as the repair of defective and deteriorated coating/lining. This document also provides requirements for shop performance testing of the coated/lined samples and the criteria for their approval.

This document specifies a test method for continuous process analysis (real-time analysis) using near-infrared spectroscopy for the indirect determination of the following fuel-characterising parameters:

— total chlorine content;

— water content;

— heating value.

NOTE When accuracy is proven, real-time analysis can be supplemented by further fuel-characterising parameters.

This document applies to solid recovered fuels according to ISO 21640.

This document specifies a method for the determination of cetane number of diesel fuels by air flow regulation in a standard test engine. This document is applicable to various types of diesel fuels, including vehicle diesel, bio-diesel, synthetic diesel, and similar unconventional products. The cetane number measurement range is from 0 CN to 100 CN, whereas a typical cetane number range of 25 CN to 70 CN. However, the precision for synthetic and unconventional diesel has not been established.

This document provides guidelines on implementation and application of the concept of metrological traceability in measurements supporting the exploration, upgrading, transmission, distribution and use of natural gas, biogas, biomethane and other substitutes. The guidance aims at implementing requirements such as those laid down in ISO/IEC 17025:2017 6.5. The measurement of flow rate, composition, temperature, pressure and natural gas properties are covered. The document also addresses the metrological traceability of properties calculated from other quanties, such as pressure, temperature and composition.

This document describes how calibration, quality control and the evaluation of measurement uncertainty aid to establishing and underpinning the metrological traceability of measurement results. Requirements for the certification of traceable calibration gas mixtures and test gases are also addressed in this document.

Finally, the guidance extends to the measurement of the quantity and energy supplied or received, such as described in ISO 15112. Whereas it is recognised that the measurement of quantity and energy is in practice often implemented as a computational process using measurement data, this document takes the view that the purpose of the measurement is the quantity and energy, and that the measurements made in gas metering serve the purpose of providing metrologically traceable results as input for the measurement of quantity and energy.
