适用范围：This International Standard specifies the apparatus, the reagents and the procedure to be used in conducting the neutral salt spray (NSS), acetic acid salt spray (AASS) and copper-accelerated acetic acid salt spray (CASS) tests for assessment of the corrosion resistance of metallic materials, with or without permanent or temporary corrosion protection. It also describes the method employed to evaluate the corrosivity of the test-cabinet environment. It does not specify the dimensions or types of test specimens, the exposure period to be used for a particular product, or the interpretation of results. Such details are provided in the appropriate product specifications. The salt spray tests are particularly useful for detecting discontinuities, such as pores and other defects in certain metallic, organic, anodic oxide and conversion coatings. The neutral salt spray test (NSS) is the test method in which a neutral 5 % sodium chloride solution is atomized under a controlled environment. It particularly applies to: — metals and their alloys, — metallic coatings (anodic and cathodic), — conversion coatings, — anodic oxide coatings, and — organic coatings on metallic materials. The acetic acid salt spray (AASS) test is the test method in which an acidified 5 % sodium chloride solution with the addition of glacial acetic acid is atomized under a controlled environment. It is especially useful for testing decorative coatings of copper + nickel + chromium, or nickel + chromium. It has also been found suitable for testing anodic and organic coatings on aluminum. The copper-accelerated acetic acid salt spray test (CASS) is the test method in which an acidified 5 % sodium chloride solution with the addition of copper chloride and glacial acetic acid is atomized under a controlled environment. It is useful for testing decorative coatings of copper + nickel + chromium, or nickel + chromium. It has also been found suitable for testing anodic and organic coatings on aluminum. The salt spray methods are all suitable for checking that the comparative quality of a metallic material, with or without corrosion protection, is maintained. They are not intended to be used for comparative testing as a means of ranking different materials relative to each other with respect to corrosion resistance or as means of predicting long-term corrosion resistance of the tested material.

适用范围：This document specifies terminology, principles and a process for risk management of medical devices, including software as a medical device and in vitro diagnostic medical devices. The process described in this document intends to assist manufacturers of medical devices to identify the hazards associated with the medical device, to estimate and evaluate the associated risks, to control these risks, and to monitor the effectiveness of the controls. The requirements of this document are applicable to all phases of the life cycle of a medical device. The process described in this document applies to risks associated with a medical device, such as risks related to biocompatibility, data and systems security, electricity, moving parts, radiation, and usability. The process described in this document can also be applied to products that are not necessarily medical devices in some jurisdictions and can also be used by others involved in the medical device life cycle. This document does not apply to: — decisions on the use of a medical device in the context of any particular clinical procedure; or — business risk management. This document requires manufacturers to establish objective criteria for risk acceptability but does not specify acceptable risk levels. Risk management can be an integral part of a quality management system. However, this document does not require the manufacturer to have a quality management system in place. NOTE Guidance on the application of this document can be found in ISO/TR 24971[9]. [9] ISO/TR 24971, Medical devices — Guidance on the application of ISO 14971

适用范围：This international standard specifies a method for consolidated triaxial compression tests on watersaturated soils. This international standard is applicable to the laboratory determination of triaxial shear strength under compression loading within the scope of geotechnical investigations. The cylindrical specimen, which may comprise undisturbed, re-compacted, remoulded or reconstituted soil, is subjected to an isotropic or an anisotropic stress under drained conditions and thereafter is sheared under undrained or drained conditions. The test allows the determination of shear strength, stress-strain relationships and effective stress paths. All stresses and strains are denoted as positive numerical values in compression. Special procedures such as: a) tests with lubricated ends; b) multi-stage tests; c) tests with zero lateral strain (K0) consolidation; d) tests with local measurement of strain or local measurement of pore pressure; e) tests without rubber membranes; f) extension tests; e) shearing where cell pressure varies; h) shearing at constant volume are not fully covered in this standard procedure. However, these specific tests may refer to general procedures described in this standard. NOTE – This document fulfils the requirements of consolidated triaxial compression tests for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

适用范围：This document specifies the fundamental formulae for use in tooth bending stress calculations for involute external or internal spur and helical gears with a rim thickness sR > 0,5 ht for external gears and sR > 1,75 mn for internal gears. In service, internal gears can experience failure modes other than tooth bending fatigue, i.e. fractures starting at the root diameter and progressing radially outward. This document does not provide adequate safety against failure modes other than tooth bending fatigue. All load influences on the tooth root stress are included in so far as they are the result of loads transmitted by the gears and in so far as they can be evaluated quantitatively. This document includes procedures based on testing and theoretical studies such as those of Hirt[11], Strasser[14] and Brossmann[10]. The results are in good agreement with other methods (References [5], [6], [7] and [12]). The given formulae are valid for spur and helical gears with tooth profiles in accordance with the basic rack standardized in ISO 53. They can also be used for teeth conjugate to other basic racks if the virtual contact ratio εαn is less than 2,5. The load capacity determined on the basis of permissible bending stress is termed “tooth bending strength”. The results are in good agreement with other methods for the range, as indicated in the scope of ISO 6336-1. If this scope does not apply, refer to ISO 6336-1:2019, Clause 4. [10] Brossmann U.
