This part of ISO 13584 specifies a supplier code to identify the information suppliers of the contents of
a library and, when the content of this library was provided in a standard document, a code that
identifies this standard document.
The following are within the scope of this part of ISO 13584:
— a code to identify the supplier of information contained in a parts library, and
— a code to identify a standard document when the content of a parts library are defined in a
standard document.
The following is outside the scope of this part of ISO 13584:
— a code to identify the supplier of a part.
NOTE The supplier code enables the user of a library to trace the supplier of any information about a
part that has an entry in the library and to trace the data given by a particular information supplier.
ISO 13584-25:2004 provides generic EXPRESS resource constructs that support the description of aggregate data types and values occurring in supplier libraries. It also contains an integrated EXPRESS information model for representing supplier libraries for the purpose of exchange. This integrated information model integrates the above resource constructs with other EXPRESS resource constructs from different parts of ISO 13584 and ISO 10303 into one single schema. Supplier libraries may consist of definitions and of representations of families of parts. They may also define new representation categories. Supplier libraries may consist only of dictionary elements with or without aggregate data types, or they may also contain explicit specifications of the sets of permitted instances.
When used together with view exchange protocols, this integrated information model also permits the exchange of one or several representation categories for the parts defined in a parts library.
The following are within the scope of ISO 13584-25:2004:
generic resource constructs for representing aggregate data types. Aggregate data types and values are modelled according to the definition of aggregate data types of the EXPRESS language (ISO 10303-11);
generic resource constructs for representing aggregate values;
generic resource constructs for representing assembled parts that may contain an unlimited number of constituent components;
a library integrated information model that provides for modelling and exchanging supplier libraries that contain properties whose values may be aggregate-structured, and whose possible class extensions are explicitly described as sets of instances.
The following are outside the scope of this part of ISO 13584-25:2004:
representation of expressions and variables;
implicit description of the set of permitted instances of a class by means of constraints;
specification of a software system able to manage supplier libraries represented according to the information models defined in ISO 13584-25:2004.
ISO 13584-24:2003 provides generic EXPRESS resource constructs that support the description of different kinds of information about supplier libraries. It also contains a set of integrated EXPRESS information models for representing supplier libraries for the purpose of exchange. These integrated information models integrate EXPRESS resource constructs from different parts of ISO 13584 and ISO 10303 into a single schema.
Three integrated EXPRESS information models are defined in ISO 13584-24:2003. They permit respectively the exchange of libraries which consist either of definitions of families of parts, representations of families of parts or definitions of new representation categories that may be provided for any family of parts.
These integrated EXPRESS information models contain provisions that permit a supplier library to reference external files. For each integrated EXPRESS information model, ISO 13584-24:2003 specifies which formats are allowed for these external files. Other external file formats are defined in the view exchange protocol series of parts of ISO 13584.
This part of ISO 13584 specifies:
— an EXPRESS schema for generic expressions;
— an EXPRESS schema for expressions, that models the subset of the allowed expressions in the EXPRESS language defined in ISO 10303-11 that corresponds to integer, real, Boolean and string data types. This schema uses the resources defined in the generic expression schema.
The following are within the scope of this part of ISO 13584:
— the exchange of expressions that involve both constants and variables;
— the function that checks whether or not a numeric expression should evaluate to an integer value;
— the constraints which ensure that an expression is semantically correct;
— the computation of the variables or functions used in an expression;
— the function that checks if an expression may be mapped on to the SQL query language. The following are outside the scope of this part of ISO 13584:
— the assignment of values to variables within some context;
— the triggering mechanism that computes the value of an expression in a given context.
ISO 21930:2017 provides the principles, specifications and requirements to develop an environmental product declaration (EPD) for construction products and services, construction elements and integrated technical systems used in any type of construction works.
ISO 21930:2017 complements ISO 14025 by providing specific requirements for the EPD of construction products and services.
ISO 21930:2017 establishes a core set of requirements to be considered as core product category rules (PCR) to develop an EPD for any construction product or service.
In addition, this document, as the core PCR document for construction products, construction elements and integrated technical systems:
a) includes the rules for calculating the life cycle inventory analysis (LCI), the predetermined environmental indicators and the life cycle impact assessment (LCIA) results that are reported in the EPD;
b) describes which life cycle stages are considered in a particular type of EPD, which processes are to be included in the life cycle stages and how the stages are subdivided into information modules;
c) defines rules for the development of scenarios;
d) includes the rules for reporting relevant environmental and technical information that are not covered by LCA;
e) defines the core elements to be included in an EPD;
f) establishes the structure of a project report;
g) defines the conditions under which construction products can be compared, based on the information provided by an EPD;
h) provides requirements and guidelines on PCR for sub-categories of construction products;
i) includes mandatory and unalterable requirements for any PCR based on this document.
EPDs for construction products, as described in this document, are primarily intended for use in B2B communication, but their use in B2C communication under certain conditions is not precluded. For EPDs intended for B2C communication, refer to ISO 14025 (see 5.4).
The assessment of social and economic impacts at the product level is not covered by this document.
NOTE 1 In this document, unless otherwise designated, the term construction product is used for any good(s) or service(s) related to construction works.
NOTE 2 Construction assemblies, construction elements and integrated technical systems, incorporated within construction works, can be considered construction products.
