INTRODUCTION
Every product has an effect on the environment, which may occur at any or all stages of its
life cycle – raw-material acquisition, manufacture, distribution, use, and disposal. These
effects may range from low to significant; they may be short-term or long-term; and they may
occur at the local, regional or global level (or a combination thereof).
The interest of customers, users, developers and other stakeholders in environmental
aspects and effects of products is increasing.
Anticipating or identifying the environmental aspects of a product throughout its life cycle
may be complex. The environmental aspects of a product have to be balanced against
other factors, such as its intended use, performance, safety and health, cost, marketability,
quality and regulatory requirements. It is important to consider the product functionality within
the context of the system where it will be used.
The process of integrating environmental aspects into product design and development has
to be continuous and flexible, promoting creativity and maximizing innovation and
opportunities for environmental improvement. Environmental issues should be addressed in
the policies and strategies of the organization involved.
Early identification and planning enable organizations to make effective decisions about
environmental aspects that they control. This provides a better understanding of how their
decisions will affect environmental aspects controlled by others, for example, at the raw-
material and parts acquisition or end of life stages.
The purpose of this document is to help designers of products in the field of audio/video,
information technology and communication technology to appropriately manage related
environmental issues within the design process.
This sector specific document takes into account the publication of the first edition of
IEC Guide 114 (2005), the publication of the second edition of ECMA-341 ( 2004), recent
engineering best practices as well as current market and regulatory environmental product
requirements.

1 Scope
This International Standard applies to all audio/video, information and communication
technology equipment marketed as final products, hereafter referred to as products.
Although this standard does not explicitly apply to individual components and subassemblies
to be incorporated into final products, component manufacturers also need to consider this
standard, to enable manufacturers using such components to meet the requirements herein.
Only the intended use of products as defined by the manufacturer is within the scope of this
standard.
This standard specifies requirements and recommendations for the design of environmentally
sound products regarding
• life cycle thinking aspects,
• material efficiency,
• energy efficiency,
• consumables and batteries,
• chemical and noise emissions,
• extension of product lifetime,
• end of life,
• hazardous substances/preparations, and
• product packaging.
This standard covers only criteria directly related to the environmental performance of the
product. Criteria such as safety, ergonomics and electromagnetic compatibility (EMC) are
outside the scope of this standard and covered by other standards.

4 Life cycle thinking (LCT) aspects
Within the limits of the designer’s responsibility, the designer shall consider life cycle
thinking (LCT). LCT means integration of the environmental impact caused by a product
throughout all life cycle stages as early as possible in the product design and development
process when opportunities exist to make decisions to improve the environmental
performance of the product.
Basic considerations require that:
– a goal to minimize the overall adverse environmental impact be defined by the
manufacturer/organization;
– the significant environmental aspects of the product be identified and
– trade-offs associated with both environmental aspects and life cycle stages be
considered.
– 10 – 62075 © IEC:2008
Balanced compromises associated with both environmental aspects and the life cycle
stages shall be considered. Any decision should be balanced with technical features and
economic viability and shall not compromise health and safety.
NOTE The goal of integrating environmental aspects into product design and development is the reduction of
adverse environmental impacts of the product throughout its entire life cycle. The life cycle of any product
includes the extraction and processing of raw materials, manufacturing, transportation, use and end of life
management (including reuse, recycling and final disposal). Each of these life cycle stages consumes resources
and generates environmental impacts in air, water or soil.
It is not the designer’s sole responsibility to deal with attributes not directly dependent on the product design.
First, the designer should ensure that products comply with all relevant regulations governing product design.
Then, the designer should take into account the environmental impact of the product throughout its life to
identify the significant impacts that can be reduced by alternative design solutions.
General environmental aspects of life cycle stages such as extraction/processing of raw materials,
manufacturing and transportation should be considered within existing environmental and procurement policies and
guidelines of the organization. Designers should follow the design relevant aspects of those policies and
guidelines.
Any emphasis on a single stage of a product’s life cycle may alter another stage and therefore the overall
environmental impact. The designer’s responsibility is limited by the possibilities within the requested
functionalities and market requirements. Balanced compromises will occur in optimizing environmental impact
across the product life cycle.
5 Design requirements and recommendations
5.1 General considerations
The following requirements have been compiled for use when designing and developing
products as defined in the scope of this standard, as far as they can be practically influenced
by the designer.
The designer
– shall identify the latest environmental related legal and market requirements (from
customers, government, environmental groups, industrial associations, etc.);
– should do benchmarking addressing the comparison of energy efficiency, material
efficiency, and the use of hazardous substances and preparations;
– should gather and evaluate experience from the subsequent manufacturing, sales,
product usage, maintenance and disposal stages;
to continually improve the process of environmentally conscious product design.
The entire environmental performance of the product should be evaluated, while the
considerations should give priority to those factors that can be substantially influenced
through product design and are identified as major environmental impacts (for example,
very often energy consumption). The evaluation should take into consideration the functions
and normal usage of the product as well as the technical and economical feasibility.
As a minimum, the designer shall document decisions by some means, such as by
maintaining a design checklist covering environmental aspects (an example for such a
checklist is provided in Annex A).
This standard requires certain product environmental characteristics to be made available in
a form the manufacturer deems appropriate.
Further applicable information may be made available in an environmental product
declaration (for example, ECMA-370).

62075 © IEC:2008 – 11 –
5.2 Material efficiency
Material selection has an impact on the environment. When specifying materials, the
designer should consider design alternatives that:
– reduce the variety of materials used;
– reduce the amount of material used and consequently the weight of the product;
– use materials that are considered to have lower adverse environmental impact;
– seek to use materials that can be easily recycled.
Material-related end of life aspects are covered in 5.7. For replacing materials containing
hazardous substances and preparations, see 5.8.
5.3 Energy efficiency
5.3.1 General
To focus efforts on increasing energy efficiency, the designer shall be aware in which stage
of the product life cycle the product will consume the most energy.
The intended use patterns of the product, including where relevant its typical system
interactions, shall be considered. Where possible, the organization should strive for
improving the overall system performance in respect to energy efficiency.
Energy consumption information shall be made available (see 5.3.5 d) and 5.3.7).
5.3.2 Energy modes and related energy efficiency measures
Energy mode definitions and applied terms vary depending on the product group. Therefore,
rather than providing precise definitions of energy modes in this standard, modes are
described in generic terms as defined in 5.3.3 to 5.3.6 and illustrated in Figure 1. The intent is
to balance the technical complexity with the simplicity needed for ease of communication and
use.
NOTE Due to the high diversity of products covered by this standard, examples are intended to clarify the energy
modes and to guide the designer.
The designer shall identify specific energy modes that apply to the product under
development.
The designer shall consider energy efficiency measures for the identified energy modes
(described in more detail in the following subclauses).
Designers shall also identify where energy is consumed with the product and take steps to
reduce the overall energy consumption.

IEC  2367/07
Figure 1 – Energy mode classification
5.3.3 Operational modes
Products perform their intended functions in the on-maximum, on-normal and on-idle
operational modes.
− On-maximum: Operation with all options in use.
EXAMPLE 1 A television with maximum contrast, brightness and sound, or a personal computer with all slots and
bays populated and operating.
− On-normal: Operation with default/standard configuration.
EXAMPLE 2 The factory setting of a computer display or a printer in active/run mode.
− On-idle: Operation with minimum system load by user and ready to operate without delay.
EXAMPLE 3 A personal computer running with no user initiated task consuming significant computing resources,
or a printer in ready mode.
The designer shall consider:
– using low power components and/or design options as well as efficient power supply
components to reduce the energy consumption in the on modes.
NOTE 1 The reason for the above is that less efficient designs result in higher heat dissipation in
the system, which leads to increased cooling requirements. By improving the energy efficiency of
these designs in the on-mode, it may become possible to apply passive cooling thereby avoiding
the use of fans and the resulting additional energy consumption.
NOTE 2 Energy efficiency improvements typically reduce costs and noise and improve
serviceability.
62075 © IEC:2008 – 13 –
– identified modes (see 5.3.2) when specifying the power supply. The AC-DC conversion
efficiency should be high in the most used modes, for example, by applying voluntary
programs and agreements as described in 5.3.7.
EXAMPLE 4 For typical personal computers in office use, the on-idle mode might represent a substantial
percentage of the on-mode consumption and thus the conversion efficiency for this mode should be high. However,
in many personal computers, the power supply loading is low in the on-idle mode, and hence often the conversion
efficiency is low.
NOTE 3 Another reason for a low loading and therefore reduced power supply efficiency is the inherent
extendibility of a system such as a personal computer. As such, the designer should balance extendibility vs.
energy consumption.
– the true specification needs for the product. For example, over-specifying the rating of the
power supply can lead to an energy inefficient design.
– the effect of the operating environment specification provided to users and installers. For
example, over-specifying the maximum allowed ambient (room) operating temperature for
large telecom, server or storage units can lead to energy inefficiencies in the room cooling
systems.
5.3.4 Energy saving modes
Energy saving modes, often denoted as low power, sleep, deep sleep or stand-by, are states
in which the equipment is connected to an electrical supply and is ready to resume an
operational mode, within a user acceptable timeframe, through the use of remote control or
another signal. In complex systems, various energy save modes may be present.
EXAMPLE 1 Sleep [stand-by/suspend to RAM (random access memory) mode for computers], stand-by-active
high mode (set-top-box exchanging data with an external source but not providing picture or sound to the
television), stand-by-active low mode (DVD-recorder programmed for recording but not recording/providing picture
or sound to the television), stand-by-passive (television not providing picture or sound, but can be switched into
operational mode by the remote control).
The designer shall:
− consider practical design options to automatically switch from on mode to energy save
modes. The energy save mode settings should be adjustable by the user and designed in a
way that it is likely to be adjusted if necessary to an alternative or custom setting, more
suitable to their typical use. Other innovative solutions shall be considered;
EXAMPLE 2 A computer monitor may activate sleep mode when the user is detected to have left the viewing area
or after a specified period of inactivity of manual input devices such as keyboard and mouse.
− consider the effect of the time to resume on the user acceptance to use the energy save
modes;
EXAMPLE 3 The delay time for the first copy/print to start from energy save mode on a copier/printer.
− consider design options to reduce the energy consumption in the energy save modes by
also applying similar methods as described in 5.3.3;
− inform the user of the higher energy consumption if the energy save mode is disabled.
5.3.5 Off modes
While connected to an electrical supply, products consume the least power in the following
off modes:
− Soft-off: The equipment is switched off by the device itself or initiated by the user via
remote control or command.
EXAMPLE 1 Printer in auto-off mode or computer after shutdown was completed.
− Hard-off: The off-power state in which the device uses zero watt (minimum energy
consumption might occur due to line filters). The equipment is manually switched off with
the main power switch [see c) and d) below].
EXAMPLE 2 Monitors, televisions and laser printers switched off at the primary side of the power supply and thus
consuming no energy.
– 14 – 62075 © IEC:2008
The designer shall
a) consider design options to automatically switch from energy save mode to an off mode
where practical,
b) consider design options to reduce the energy consumption in the soft off modes to lowest
values (minimum energy consumption might occur due to line filters),
c) consider a main power switch. If applicable, the main power switch should be placed on
the product such that the user can easily reach and use it,
d) prepare energy consumption data (energy level in watthours) for a state a user would
consider hard off but for which a power level of zero watt is not achievable and inform the
user through documentation or other means.
5.3.6 No load mode
No load mode is the mode in which external power supplies or chargers are connected to an
electrical supply, but are not connected to electrical or electronic equipment for which they
have been designed.
EXAMPLE A mobile phone charger is plugged in, but the phone is not connected.
The designer shall consider design options that reduce energy consumption of no load mode
to the lowest value.
5.3.7 General energy efficiency measures
All available energy saving features shall be documented during the design process.
Information on the product’s energy consumption and, where applicable, its related energy
modes shall be made available to the user.
Designers shall consider the requirements of international programmes, applicable for the
product category, aimed to increase energy efficiency.
EXAMPLE 1 The Energy Star international programme has made a number of product specifications and
memoranda of understanding, available here: http://www.energystar.gov.
Designers should consider other agreements as applicable aimed to improve energy
efficiency.
The effects of the improved design decisions compared to previous similar designs should be
quantified and communicated to product marketing departments in order to enable them to
promote products with lower adverse total environmental impact through lower energy
consumption.
The designer should enable the most energy efficient on modes and transitions to energy
saving mode as the default modes with performance taken into consideration after transitions
to energy saving modes as the default mode. If this is not reasonably achievable, the user
shall be made aware of this and instructions on proper use of available energy saving controls
and/or settings shall be provided to users. Instructions may be included in product user
documentation in either printed or electronic form.
EXAMPLE 2 A user should be made aware that enabling the wake-up on Local Area Network features prevents
the product from entering the soft-off energy saving mode.
If the product applies software and/or firmware, the designer shall be aware of the relevance
of those for the overall energy efficiency of a system. The designer should balance the
flexibility of software running on multipurpose devices and the energy efficiency of special
purpose hardware.
62075 © IEC:2008 – 15 –
5.4 Consumables and batteries
5.4.1 Consumables
For consumables, designers shall also consider the guidance specified in 5.7.
Products should be designed such that the use of consumables can be optimized relative to
the functionality of the product. Designers should consider:
– functions to reduce or save the use of consumables;
– ease of replacement and maintenance of consumables.
The manufacturer shall provide users with information on the proper use of consumables
relative to the functionality of the product and, where appropriate, end of life management of
the consumables.
5.4.2 Batteries
Batteries shall comply with all applicable restrictions such as on hazardous substances and
preparations (see 5.8), design requirements on equipment containing batteries and, to the
extent possible, all international labelling requirements.
Batteries with reduced environmental impact shall be considered. When materials with
adverse environmental impact cannot be avoided (for example, mercury in button cells), the
material and its justification shall be documented during the design process.
Batteries shall be easily identifiable and removable, either by users or skilled persons,
except where the battery life span exceeds that of the product. In case the life span of the
battery exceeds that of a product, batteries shall be removable for end of life treatment.
Product documentation shall give advice for the safe removal of the battery by either users or
skilled persons. Information on batteries in the product shall be made available. This
information shall include details on the types of the batteries and their locations, as well as
proper procedures for safe removal and handling of the batteries, including information on
end of life management/proper battery disposal.
Designs that prolong the durability of batteries shall be considered.
5.5 Emissions
5.5.1 Chemical emissions
Products shall be designed such that chemical emissions with adverse environmental
impact during use are reduced wherever possible.
For products that use an electrostatic process, emission rates determined according to
ISO/IEC 28360 should be made available.
5.5.2 Noise emissions
The designer shall consider techniques to reduce noise emissions.
NOTE 1 Reduced noise emissions improve energy efficiency.
In particular, noise emissions shall be evaluated according to ISO 7779, for products covered
by ISO 7779 (or ECMA-74).
– 16 – 62075 © IEC:2008
For products under the scope of this standard and not covered by a product specific
international standard noise test code, such as ISO 7779 (or ECMA-74), noise emissions do
not have to be evaluated.
If noise emissions are evaluated for products under the scope of this standard but not
covered by either ISO 7779/ECMA-74 or another product-specific international standard
noise test code, the basic sound power standards, ISO 3741, ISO 3744 or ISO 3745, and the
basic emission sound pressure standard, ISO 11201, shall be used. The test conditions used
should be recorded.
The resulting sound power levels and, where applicable, emitted sound pressure levels
(including emission sound pressure measurement distance if not covered by
ISO 7779/ECMA-74) shall be declared according to ISO 9296 (or ECMA-109) and should be
documented according to available eco-declaration standards (such as ECMA-370). The
levels shall be made available in the product information.
NOTE 2 The additional noise from cooling systems is a frequent issue for audio and video systems and
computers in home or silent office environments.
NOTE 3 The declared A-weighted sound power level L , according to ISO 9296, is a statistical maximum value
WAd
to account for product variation and lab-to-lab variations, and L is typically about 0,3 bels – 0,4 bels (3 dBA –
WAd
4 dBA) greater than the average A-weighted sound power level L , measured according to ISO 7779, ISO 3741,
WA
ISO 3744 or ISO 3745. ISO 9296 (or ECMA-109) specifies how to determine and verify L .

5.6 Product lifetime
Where technically and economically feasible, products shall be designed to have a prolonged
useful life and be easy to upgrade and repair. However, designers shall consider the
balanced compromise of using up to date and efficient technology and prolonging the life of
inefficient products. Designers shall consider incorporating the following features:
− use of common mechanical packages (such as covers and chassis) or common parts or
components that are used for multiple models in the product family or in multiple
generations of the same product, allowing for the reuse of common parts;
− use of standardised parts that may be more easily replaced or repaired;
− use of modules;
− reuse of modules, parts and products, whenever applicable. Parts, which may be
targeted for reuse (for example, in maintenance and spare parts applications) should be
identified.
To encourage the optimisation of a product’s useful life, information on available options for
upgrading, expanding and repair of products shall be made available if appropriate.
NOTE 1 Specifics on design for upgradeability may need to be identified based on product categories, and/or
initial cost of a product. There are categories of products for which upgradeability features may not be applicable,
for example, single use cameras and pocket calculators.
NOTE 2 Some of the guidelines provided in this subclause will aid serviceability.
5.7 End of life
Product design shall facilitate reuse, recycling and proper disposal at end of life.
The following design principles, where appropriate for the expected end of life processes,
shall be applied:
− easy and safe separation of parts containing hazardous substances and preparations
shall be possible (see 5.8);
− materials (including electronic modules) connected to case/housing parts or chassis
intended for different end of life treatment shall be easily separable;

62075 © IEC:2008 – 17 –
− disassembly down to the module level (for example, power supply, disk drive, circuit board)
shall be possible usi
