This document specifies an automatic particle counting procedure for determining the number and sizes of particles present in hydraulic-fluid bottle samples of clear, homogeneous, single-phase liquids using an automatic particle counter (APC) that works on the light-extinction principle.

This document is applicable to the monitoring of:

a)      the cleanliness level of fluids circulating in hydraulic systems;

b)      the progress of a flushing operation;

c)       the cleanliness level of support equipment and test rigs;

d)      the cleanliness level of packaged stock fluid.

NOTE           Measurements can be made with particles suspended in the original liquid or in a sample of the liquid diluted with a compatible liquid when APC coincidence error limits are exceeded.

This document specifies a bubble-point test method applicable to filter elements used in hydraulic fluid power systems. It can be used both to verify the fabrication integrity of a filter element (by checking the absence of bubbles) and to permit the localization of the largest pore of the filter element by determining the first bubble point.

NOTE Verification of fabrication integrity is used to define the acceptability of the filter elements for further use or testing.

The first bubble point is established through continuation of the fabrication integrity test. It is under no circumstances a functional characteristic of a filter element; in particular, it cannot be used to estimate filtration rating, efficiency or retention capacity and is intended to be used for information only.

This document specifies a method to normalise fabrication integrity and bubble point data to a standard value of surface tension when test fluids other than 2-propanol are used.

This International Standard specifies ways in which rare earths can be traced as they move through the supply chain between the separated products to rare earth permanent magnets, or otherwise further processed. This standard complements ISO 23664.

 

The documented traceability information will assist purchasers, suppliers, and users of rare earth permanent magnets to identify parties in the supply chain who have processed a given shipment of rare earth material, the location of that rare earth material as it passes between supply chain nodes. Supply chain actors and end users can use this information to check the validity of any claims made on the rare earth permanent magnets concerning sustainability, environmental impact, or recycled material content.

 This document establishes concepts for understanding and improving systems resilience. Systems resilience addresses the capabilities of systems under adversity. Broadly, systems resilience involves the capabilities of systems to avoid, withstand, and recover from adversity. Adversities can be known or unknown and can arise in many ways, such as security threats, dangers affecting safety, financial and business impacts from external system disruptions, from internal system faults and defects, and from adverse effects of disclosure or loss of data and information. Resilience goals are realized through application of techniques during requirements, architecture, design or operations processes of a system. This document is applicable to human-created systems that can be either physical or conceptual, or a combination of both. Systems include services and products. It is not intended to apply to naturally occurring systems.

This document is applicable to the evaluation of a substrate's resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions.

This document is intended to provide a guide to oil stain resistance. It can provide a rough index of oil stain resistance as, generally, the higher the oil repellency grade, the better resistance to staining by oily materials, especially liquid oil substances. This is particularly true when comparing various finishes for a given substrate. This International Standard can also be utilized in determining if washing and/or drycleaning treatments have any adverse effect on the oil repellency characteristics of a substrate.

NOTE Washing and drycleaning treatment procedures are described in ISO 6330 or ISO 3175 (all parts), respectively.

This document is not intended to give an absolute measure of the resistance of the substrate to staining by all oily materials. Other factors, such as composition and viscosity of the oily substances, substrate construction, fibre type, dyes and other finishing agents, also influence stain resistance. This International Standard is not intended to estimate the resistance to penetration of the substrate by oil-based chemicals.

NOTE For the evaluation of the resistance to penetration of the substrate by oil-based chemicals, see ISO 6530

This document specifies procedures suitable for the analysis of data which, when converted into logarithms of the values, have either a normal or a skewed distribution. It is intended for use with test methods and referring standards for glass-reinforced thermosetting plastics (GRP) pipes or fittings for the analysis of properties as a function of time. However, it can also be used for the analysis of other data. Two methods are specified, which are used depending on the nature of the data. Extrapolation using these techniques typically extends a trend from data gathered over a period of approximately 10 000 h to a prediction of the property at 50 years, which is the typical maximum extrapolation time. This document only addresses the analysis of data. The test procedures for collecting the data, the number of samples required and the time period over which data are collected are covered by the referring standards and/ or test methods. Clause 6 discusses how the data analysis methods are applied to product testing and design.

 This document establishes the default specification operator (see ISO 17450-2) and defines a special specification operator for linear sizes. It applies to the following features of linear size: — cylinders, — spheres, — two parallel opposite planes. Annex C handles the definition of sizes for circles as sections of a cone. Annex D handles the definition of sizes for circles as sections of a torus. Annex E handles the definition of sizes for parallel opposite lines as longitudinal sections of cylindrical tubes in half planes containing a specified axis. This part of ISO 14405 provides a set of tools to express several types of linear size characteristics. It does not present any information on the relationship between a function or a use and a linear size characteristic.
