The primary purpose of this International Standard is the provision of data structures for electronic

product catalogues to transmit building services product data automatically into models of building

services software applications. This includes a meta model for the specification of product classes

and their properties and a meta model for the product data which is exchanged in product catalogues.

Product data has to follow the specifications for their product groups.

The standard series is split into two areas:

— Basic concepts like conceptual models, languages, geometry representations, and XML schemas for data

exchange are provided in the Conceptual Parts of the standard series (Parts with a one digit number).

— Using these resources, the Content Parts of this International Standard define for various product

groups of building services concrete models for the description and the exchange of products.

The basic concepts which are provided by the standard series include the following:

— resources for the specification of selection properties and a selection property tree guiding the

selection process to identify the appropriate product variant from a parametric electronic catalogue;

— resources for the specification of dependent properties and their computational functions to

compute their values in dependency from installation parameters;

— resources for the specification of composition relationships between products which can be used to

model structures like bill of materials or accessory relationships;

— resources for a parametric constructed solid geometry (CSG) based geometry representation containing

specific CSG elements geometrical elements which are typical for building services products.

This part of ISO 16757 specifies

— the underlying concepts,

— a generic model specifying the available modelling elements and their relationships, and

— a framework for the specification of the Content Parts by describing the elements which are to be

provided by these Parts.

Not in scope of this part of ISO 16757 are the following:

— a detailed description of the used geometrical primitives;

NOTE Geometry is described in ISO 16757-2.

— a specification of the script language used to exchange algorithms for computing the values of

dependent and computable properties;

NOTE The script language is described in ISO 16757-3.

— a specification of the XML Schema specifying the data structures for the catalogue exchange;

NOTE The XML schema is described in ISO 16757-5.

— a description of the relationships to standards of the area of buildingSMART;

NOTE The relationships to standards of the area of buildingSMART is described in ISO 16757-4.

— definition of models for specific product groups.

NOTE 1 Definitions of models for specific product areas are described in ISO 16757-10 et. seq., the Content

Parts of ISO 16757.

NOTE 2 All parts are still under development.

This part of ISO 16757 describes the modelling of building services product geometry. The description is optimized for the interchange of product catalogue data and includes

— shapes for representing the product itself,

— symbolic shapes for the visualization of the product’s function in schematic diagrams,

— spaces for functional requirements,

— surfaces for visualization, and

— ports to represent connectivity between different objects.

The shape and space geometry is expressed as Constructive Solid Geometry (CSG) based on geometric primitives concatenated to boundary representations by Boolean operations. This part of ISO 16757 uses the applicable primitives from ISO 10303-42 and from ISO 16739 and adds primitives which are required for the special geometry of building services products. For symbolic shapes, line elements are also used.

This part of ISO 16757 neither describes the inner structure and internal functionality of the product nor the manufacturing information because this is typically not published within a product catalogue.

Building services products can have millions of variant dimensions. To avoid the exchange of millions of geometries, a parametric model is introduced which allows the derivation of variant-specific geometries from the generic model. This is necessary to reduce the data to be exchanged in a catalogue to a manageable size. The parametric model will result in smaller data files, which can be easier transmitted during data exchanges.

The geometry model used does not contain any drawing information such as views, line styles or hatching.

This document specifies a framework for the identification of biological hazards and the estimation and control of biological risks from material constituents, using a stepwise approach to the characterization of a medical device through:

— the identification of its materials of construction (medical device configuration);

— the characterization of the materials of construction via the identification and quantification of their chemical constituents (material composition);

— the characterization of the medical device for chemical substances that were introduced during manufacturing (e.g., mould release agents, process contaminants);

— the estimation of the potential of the medical device, or its materials of construction, to release chemical substances under clinical use conditions (extractables);

— The measurement of chemical substances released from a medical device under its clinical conditions of use (leachables).

This document may also be used for chemical characterization (e.g., the identification and/or quantification) of degradation products. Information on other aspects of degradation assessment are covered in ISO 10993-9, ISO 10993-13, ISO 10993-14 and ISO 10993-15.

The ISO 10993 series of standards is applicable when the material or medical device has direct or indirect body contact (see ISO 10993-1 for categorization by nature of body contact).

This document is intended for suppliers of materials and manufacturers of medical devices, to support a biological evaluation.

This document applies to medical devices other than in vitro diagnostic medical devices manufactured utilizing materials of animal origin, which are non-viable or have been rendered non-viable. It specifies, in conjunction with ISO 14971, a procedure to identify the hazards and hazardous situations associated with such devices, to estimate and evaluate the resulting risks, to control these risks, and to monitor the effectiveness of that control. Furthermore, it outlines the decision process for the residual risk acceptability, taking into account the balance of residual risk, as defined in ISO 14971, and expected medical benefit as compared to available alternatives. This document is intended to provide requirements and guidance on risk management related to the hazards typical of medical devices manufactured utilizing animal tissues or derivatives such as:

a) contamination by bacteria, moulds or yeasts;

b) contamination by viruses;

c) contamination by agents causing Transmissible Spongiform Encephalopathies (TSE);

d) material responsible for undesired pyrogenic, immunological or toxicological reactions.

For parasites and other unclassified pathogenic entities, similar principles can apply.

This document does not stipulate levels of acceptability which, because they are determined by a multiplicity of factors, cannot be set down in such an International Standard except for some particular derivatives mentioned in Annex C. Annex C stipulates levels of TSE risk acceptability for tallow derivatives, animal charcoal, milk and milk derivatives, wool derivatives and amino acids.

This document does not specify a quality management system for the control of all stages of production of medical devices.

This document does not cover the utilization of human tissues in medical devices.

NOTE 1 It is not a requirement of this document to have a full quality management system during manufacture. However, attention is drawn to International Standards for quality management systems (see ISO 13485) that control all stages of production or reprocessing of medical devices.

NOTE 2 For guidance on the application of this document see Annex A.

This document specifies two methods, A and B, for the preparation of pastes (also known as plastisols) from appropriate PVC resins, plasticizers and other ingredients using a planetary mixing process.

Both method A and method B can be used to prepare pastes of any composition. Method A (single-speed) is particularly applicable to resins prone to heat build-up during paste preparation, while method B (two-speed) might be preferred for repetitive work, e.g. for process control during resin manufacture, because of its shorter mixing time.

Such pastes can be used for a variety of test purposes, including the determination of rheological properties for resin designation and specification.

This document specifies a method of determining the moulding shrinkage and post-moulding shrinkage of injection-moulded test specimens of thermoplastic material in the directions parallel to and normal to the direction of melt flow.

For the determination of shrinkage of thermosets, see ISO 2577[2].

Moulding shrinkage as defined in this document excludes the effects of humidity uptake. This is included in post-moulding shrinkage and thus in total shrinkage. For cases when post-moulding shrinkage is caused by the uptake of humidity only, see ISO 175[1].

Moulding shrinkage as defined in this document represents the so-called free shrinkage with unrestricted deformation of the cooling plates in the mould during the hold period. It is considered, therefore, as the maximum value of any restricted shrinkage.

This document considers liquid atmospheric precipitation and defines the procedures and equipment to perform laboratory and field tests, in steady-state conditions, for the calibration, check and metrological confirmation of liquid precipitation measurement instruments. It provides a classification of catching-type measurement instruments based on their laboratory performance. The classification does not relate to the physical principle used for the measurement, nor does it refer to the technical characteristics of the instrument assembly, but is solely based on the instrument calibration. Attribution of a given class to an instrument is not intended as a high/low ranking of its quality but rather as a quantitative standardized method to declare the achievable measurement accuracy in order to provide guidance on the suitability for a particular purpose, while meeting the user’s requirements.

The component metadata lifecycle needs a comprehensive infrastructure with systems that cooperate well together. To enable this level of cooperation this document provides in depth descriptions and definitions of what CMDI records, components and their representations in XML look like.

The scope of this document is to describe these XML representations, which enable the flexible construction of interoperable metadata schemas suitable for, but not limited to, describing language resources. The metadata schemas based on these representations can be used to describe resources at different levels of granularity (e.g. descriptions on the collection level or on the level of individual resources).

In ISO 24622-1:2015 the component metadata model has been standardized. This document is compliant with ISO 24622-1:2015, and also extends and constrains it at various places (see also the red parts in the UML class diagram below):

— support for attributes on both components and elements is added,

— a profile is limited to one root component, and

— an element always belongs to a specific component.

This International Standard specifies the general characteristics of fibre ropes and their constituent materials. It is intended to be used in conjunction with the standards for the individual types of fibre rope, which cover the physical properties and specific requirements for that particular product type.

This International Standard also gives some information on the use of fibre ropes and also on their inspection and retirement criteria.

This International Standard does not intend to address all of the safety matters associated with its use. It is the responsibility of the user to select a rope that is fit for purpose: of the size and with the physical properties to meet the requirements of the application and to determine the applicability of regulatory limitations prior to its use.
