This document describes acoustic emission (AE) monitoring for in-service detection, location and grading of AE sources with application to metallic pressure equipment and other structures such as bridges, bridge ropes, cranes, storage tanks, pipelines, wind turbine towers, marine applications, offshore structures etc. The monitoring can be periodic, temporary or continuous, on site or remote-controlled, supervised or automated. The objectives of AE monitoring are to define regions which are acoustically active as a result of damage or defect evolution.

This document gives the rules of definition and interpretation of general specifications defined according to ISO 8015 (general tolerancing) applicable on the whole workpiece.

The general specifications can be applied to integral surfaces only, i.e. integral lines are excluded.

The general geometrical and dimensional specifications defined in this document applies to the following:

—    for dimensional specifications:

—    for features of size:

—    linear size (±) (according to ISO 14405‑1);

—    angular size (±)(according to ISO 14405‑3);

—    for geometrical specifications:

—    for integral features:

—    geometrical specifications with the characteristic surface profile (⌓).

This document specifies the acceptance tests for verifying the performance of a laser tracker by measuring calibrated test lengths, according to the specifications of the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the laser tracker. The acceptance and reverification tests given in this document are applicable only to laser trackers utilizing a retro-reflector as a probing system. Laser trackers that use interferometry (IFM), absolute distance meter (ADM) measurement, or both can be verified using this document. This standard can also be used to specify and verify the relevant performance tests of other spherical coordinate measurement systems that use cooperative targets, such as “laser radar” systems.

NOTE          Systems, such as laser radar systems, which do not track the target, will not be tested for probing performance.

This document does not explicitly apply to measuring systems that do not use a spherical coordinate system (i.e. two orthogonal rotary axes having a common intersection point with a third linear axis in the radial direction) however, the parties may apply this part of 10360 to such systems by mutual agreement.

This document specifies:

—    performance requirements that can be assigned by the manufacturer or the user of the laser tracker,

—    the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements,

—    rules for proving conformance, and

—    applications for which the acceptance and reverification tests can be used.

This part of ISO 11979 specifies particular requirements for the biocompatibility evaluation of materials for intraocular lenses (IOLs) including the processing conditions to produce them. These requirements include evaluation of physicochemical properties that are relevant to biocompatibility. It also gives guidance on conducting an ocular implantation test.

This document defines the maximum material requirement, the least material requirement and the reciprocity requirement. These requirements can only be applied to linear features of size of cylindrical type or opposed planar type.

These requirements are often used to control specific functions of workpieces where size and geometry are interdependent, e.g. to fulfil the functions “assembly of parts” (for maximum material requirement) or “minimum wall thickness” (for least material requirement). However, the maximum material requirement and least material requirement can also be used to fulfil other functional design requirements.

This part of ISO 128 gives general rules for the execution of technical drawings (2D and 3D), as well as presenting the structure of the other parts of ISO 128. In all, ISO 128 specifies the graphical representation of objects on technical drawings with the aim of facilitating the international exchange of information on drawings and ensuring their uniformity in a comprehensive system . This part of ISO 128 is applicable to mechanical engineering, construction, architectural and ship building technical drawings. It is applicable to both manual and computer-based technical drawings.

For the purpose of this International Standard the term “technical drawing” shall be interpreted in the broadest possible sense encompassing the total package of documentation specifying the product (workpiece, subassembly, assembly).

This document specifies a measuring system for spectacle frames and related terminology. It is applicable to spectacle frames with fronts that are intended to be symmetrical.

NOTE   Minor asymmetry of only the nasal bearing surfaces has been included in this edition. Since such asymmetry does not affect the lens shapes, only the definition of bridge height is affected, having an amendment in its note 2 to entry.

This document specifies fundamental requirements for non-invasive, active and non-active ophthalmic instruments and to low-vision aids. This document is also applicable to tonometers, but not to other ophthalmic instruments which are used in contact with the globe of the eye.

This document is not applicable to operation microscopes, endoscopes and devices intended for laser investigation or laser treatment of the eye.
