Annex ZA
(informative)
Relation of this document to the Machinery Directive 2006/42/EC
ZA.1 General
CEN ISO/TR 22100-1 (identical to ISO/TR 22100-1:2015) provides for the first time a transparent
guideline how to choose the appropriate machinery safety standard(s) representing the state of the art
and to apply it/them correctly in order to achieve at a given time a level of tolerable risk by adequate
risk reduction for an actual machine. In this document, the term tolerable risk should be read as
residual risk as defined in ISO 12100-1 to be compliant with European Union (EU) legislation.
NOTE While the residual risk is defined as the risk remaining after risk reduction measures have been
implemented (see ISO/IEC Guide 51:2014, 3.8), tolerable risk is the level of risk that is accepted in a given context
based on the current values of society (see 3.2). It is generally accepted that the residual risk is equal or lower
than the tolerable risk.
Compared to the international level (where no common legal framework for machinery safety exists) at
the European Union (EU) machinery safety standards are developed by CEN and CENELEC within the
1)
legal framework of the New Approach (New Legislative Framework) to provide presumption of
2)
conformity with relevant Essential Requirements of the EU Machinery Directive 2006/42/EC .
Those standards are harmonized and provide presumption of conformity to 2006/42/EC when cited in
3)
the Official Journal of the EU .
ZA.2 Special relevance of this document for harmonized standards (type-C)
providing presumption of conformity
The methodology as specified in Clause 6 of this document provides detailed guidance for the machine
manufacturer how to choose and evaluate harmonised standards (type-C) in order to achieve
presumption of conformity with Essential Requirements of 2006/42/EC for his actual machine in
accordance with the following statement given in §111 of the Guide to the application of the Machinery
Directive 2006/42/EC:
"Application of the specifications of a C-type standard confers a presumption of conformity with the
essential health and safety requirements of the Machinery Directive covered by the standard provided
the manufacturer has determined in his risk assessment that the scope and the significant hazards
covered by the standard correspond with his actual machinery. Further practical guidance is provided
by ISO/TR 22100-1:2015."

Introduction
This Technical Report is written to assist the designer/manufacturer of machinery and related
components in understanding and navigating the different types of ISO machinery safety standards.
It identifies the different kinds of documents in ISO (see Table B.1) and explains the type-A, type-B and
type-C structure of machinery safety standards and their interrelationship with regard to the practical
design of machinery subjected to adequate risk reduction to achieve tolerable risk.
This part of ISO/TR 22100 might be helpful for standard writing committees (type-B and type-C), too.
However, it does not provide specification of the general content that is expected to be included in the
different types of machinery safety standards. This specification is given in ISO Guide 78.
This part of ISO/TR 22100 includes a visual representation of many ISO machinery safety standards
to assist in improving understanding of the interrelationships and linkages between these documents.

1 Scope
This part of ISO/TR 22100 provides assistance to the designer/manufacturer of machinery and related
components as to how the system of existing type-A, type-B and type-C machinery safety standards should
be applied in order to design a machine to achieve a level of tolerable risk by adequate risk reduction.
It explains the general principles of ISO 12100 and how this type-A standard should be used for practical
cases in conjunction with type-B and type-C machinery safety standards.
This part of ISO/TR 22100 provides assistance to standards writing committees on how ISO 12100 and
type-B and type-C standards relate and explains their function in the risk assessment and risk reduction
process according to ISO 12100.
It includes an overview of existing categories of type-B standards to assist standards readers and
writers to navigate the many standards.

4 General structure of the system of machinery safety standards
Standards on safety of machinery have the following structure:
— type-A standards (basic safety standards) giving basic concepts, principles for design, and general
aspects that can be applied to machinery;
— type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard
that can be used across a wide range of machinery;
— type-C standards (machine safety standards) dealing with detailed safety requirements for a
particular machine or group of machines.
As shown in Figure 1, ISO 12100 is the type-A standard specifying the general principles for safety of
machinery and applies to all machinery.

5 System of type-A, type-B and type-C standards
5.1 Type-A standard (ISO 12100)
The type-A standard ISO 12100 specifies the principle strategy for safety of machinery. Risk assessment
and adequate risk reduction by an iterative three-step method are the imperative measures to design a
machine to achieve a level of tolerable risk.
To implement risk assessment and risk reduction, the following actions should be taken by the designer
in the order given (see Figure 2):
a) determine the limits of the machinery, which includes the intended use and any reasonably
foreseeable misuse thereof;
b) identify the hazards and associated hazardous situations;
c) estimate the risk for each identified hazard and hazardous situation;
d) evaluate the risk and decision whether a risk reduction is needed or not;
e) eliminate the hazard or reduction of the risk associated with the hazard by means of protective
measures/risk reduction measures.
NOTE 1 For the purposes of this Technical Report, the terms “protective measure” (see ISO 12100:2010, 3.19)
and “risk reduction measure” are synonymous and referred to any action or means used to eliminate hazards
and/or reduce risks.

ISO/TR 22100-1:2015(E)
Actions a) to d) are related to risk assessment and action e) to risk reduction.
Risk assessment is a series of logical steps to enable, in a systematic way, the identification of hazards as
well as the estimation and evaluation of the risks associated with machinery.
As a result of the risk assessment, the hazards requiring risk reduction are determined. Iteration of the
process of risk assessment can be necessary to eliminate newly generated hazards as far as reasonably
practicable or to adequately reduce associated risks by the implementation of protective measures/risk
reduction measures in order to achieve tolerable risk.
Protective measures/risk reduction measures are the combination of the measures implemented by the
designer and the user in accordance with Figure 3. Measures which can be incorporated at the design
stage are preferable to those implemented by the user and usually prove more effective.
The objective to be met is the greatest practicable risk reduction. The strategy defined in this clause is
represented by the flowchart in Figure 2. The process itself is iterative and several successive applications
can be necessary to reduce the risk, making the best use of available technology. In carrying out this
process, it is necessary to take into account these four factors, in the following order of preference:
— the safety of the machine during all the phases of its life cycle;
— the ability of the machine to perform its function;
— the usability of the machine;
— the manufacturing, operational and dismantling costs of the machine.
NOTE 2 The ideal application of these principles requires knowledge of the machine design and its intended
use, the practical use of the machine, the accident history and health records, available risk reduction techniques,
and the legal framework in which the machine is intended to be used (placed on the market).
