Introduction
The ISO 20140 series specifies a method for evaluating the energy efficiency and other factors of a
manufacturing system that influence the environment, such as energy consumption, waste, and release.
The ISO 20140 series can be used for:
— benchmarking the environmental performance against a generic reference manufacturing system or
comparing between different manufacturing systems;
— alternative studies for improving environmental performance;
— setting targets for improving environmental performance;
— visualizing the environmental performance of a manufacturing system under operation;
— managing carbon footprints of products (CFP) in a supply chain;
— evaluating the environmental performance of manufacturing systems.
Expected users of the ISO 20140 series are:
a) managers who are responsible for the environmental conditions of a manufacturing system;
b) engineers who design manufacturing processes for products;
c) engineers who design a manufacturing system;
d) engineers and supervisors who are responsible for manufacturing products.
This document classifies environmental performance evaluation (EPE) data. The classification intends to
support the association of EPE data with context information and transferring them across various locations
and disciplines in the manufacturing system.
This document provides EPE data classes which are used in the aggregation process specified in ISO 20140-3
to evaluate environmental performance of a manufacturing system. This document intends to allow mapping
EPE data to various implementations based on different technologies by providing formal and technology-
independent definitions of EPE data classes. The EPE data classes are intended to be stored in concept data
dictionaries (e.g. IEC CDD).
This document is the second edition of ISO 20140-5, which replaces the first edition ISO 20140-5: 2017. The
objective and the scope of both documents are the same. Both documents define the same set of EPE data
classes. In order to improve the applicability of EPE data for evaluating various manufacturing processes,
this document defines EPE data classes by a classification scheme differently from the first edition. The
classification of the first edition is based on properties of manufacturing operations, i.e., source and time of
EPE data generation. The classification of this document is based on a general concept of a manufacturing
process, and detailed EPE data classes are defined systematically. The definitions of EPE data classes and
types of properties are given respectively in Clause 5 and Clause 6 of this document. In order to retain the
general use of the definitions, individual EPE data derived from EPE data classes and its properties are not
described in this document. Detailed individual EPE data and properties specified in the first edition of
ISO 20140-5 can be represented by using the class definitions given in this document.

3.3 Conventions for defining class definitions and properties
Words connected with underscore (e.g. EPE_data) are used for representing class definitions and properties
in Clause 4, Clause 5 and Clause 6.
Table 1 is the template used in this document for specifying an EPE data class definition.

The shaded cells indicate the meaning of associated unshaded cell.
The text in the angle bracket (i.e. “<” and “>”) in each unshaded cell describes what the cell is used for.
The "Attributes of the class definition" part of the template provides identifying information for this EPE
data class definition formatted as fields (unshaded cells) with respective values. The fields are designated ID
of the class definition, Preferred name, and Description of the class definition.
The "Preferred name of parent class definition" part of the template provides references to another EPE data
class definition (parent class definition). The EPE data class definition being specified inherits the properties
of the parent class definition, which is referenced by preferred name.
The "Property included in the class definition" part of the template provides a list of properties for inclusion
into this EPE data class definition by indicating the preferred names and the number of possible occurrences
(cardinality). The first row for the "Property included in the class definition" part of the template is used for
the classifying property of the class definition, if applicable. The preferred names of classifying properties
are represented in bold text.
The "Class definitions included in the class" part of the template provides a list of other EPE class definitions
for inclusion into this EPE data class. The EPE data class definition being defined inherits the properties of
the included EPE data class definition that is referenced by indicating the preferred name and number of
possible occurrences (cardinality).
NOTE For ease of understanding, reference subclause numbers in this document are added to the tables.
The field “Cardinality” contains a range which defines the number of constituent elements, which are
properties or EPE class definitions. The range is expressed using the following convention:
[a.b]
where:
a is the minimum number of constituent elements;
b is the maximum number of constituent elements.
EXAMPLE The number of constituent elements can be expressed as follows:
[0.1] indicates the EPE class definition has none or one constituent element;
[0.n] indicates the EPE class definition has none or as many as n constituent elements;
[1.1] indicates the EPE class definition has one constituent element;
[1.n] indicates the EPE class definition has one or as many as n constituent elements.
Table 2 specifies the template used to list subclass definitions which are EPE class definitions derived from
the class definition that is defined by the template of Table 1. It also indicates the value of the classifying
property which characterizes each subclass definition.

Coding system whose value type is CodeType.>
The template provides the definition of a specific property of EPE data (identity and meaning) and the
attributes for defining it. In some cases, additional rows are added.
Each shaded cell indicates the name of an attribute; the value is shown in the unshaded cell.
A specific property is defined by providing data in the relevant unshaded cells (i.e. the table is filled). An
“N/A” in an unshaded cell indicates that the field is not applicable to the definition of the specific property.
The attribute of Code of quantity is used for specifying the quantity of the value specified by the property in
the case where its value type is MeasureType.
NOTE Since multiple units of measure can be used for a property, identifiers of quantities defined by IEC TS 62720
is
