Introduction
This document is intended to aid standards writers in developing their safety requirements and to help
standards users understand the basis for the requirements as they are applied throughout the world.
This document is not intended to replace existing safety standards which can have been updated.
Conclusions are arrived at in some cases, but only where is unanimity amongst the various experts. In
other cases, the reasons for the divergent views are expressed.
This document is to be read in conjunction with the various safety standards. Unless approved by
the relevant standard writing organizations, the information contained in this document does not
necessarily represent the opinions of these standards writing organizations.
This document was done with EN 115-1:2017 as a reference document shown as the only one in its
normal sequence. All other codes are not in their normal sequence and logical order. They are structured
differently to EN 115-1:2017. The result incorrectly leaves the impression of incompleteness of these
standards. These standards in their original structure inclusive of their references to other standards
and requirements are however complete.
This comparison no longer includes the Australian, Korean, and Russian safety codes as there are
intentions on national level to bring theses codes in line with one of the remaining three codes.
Due to copyright issues, A17.1-2016/CSA B44-16 (North America) detailed text comparison is not
covered in this document.
Due to copyright restrictions, in this document there is no code text of ASME A17.1/B44:2016 available,
only references to relevant sections and clause numbers are made. The leading standard for the
comparison is EN 115-1:2017. The numbering sequence of the first column follows the EN 115-1:2017
structure.
In addition to the compared standards and other regulations, escalators and moving walks can be
required to conform to the requirements of other standards, as appropriate.

5 Basis for escalator and moving walk safety standards
5.1 Historical origin and development of standards
5.1.1 European Standard EN 115-1
5.1.1.1 Rationale for EN 115-1
The ever-increasing number of escalators put in operation in Europe after the second world war
required the drawing-up of guidelines for models and safety for escalators, especially as not all
European countries had their own standard or national regulation for escalators.
Therefore, specialists/experts from the European countries joined together and developed the
first draft of EN 115, which was accepted by CEN on 3rd January 1995 which has been continuously
developed since then. The last complete revised document was published in 2017
According to the Internal Regulations of CEN/ CENELEC, the CEN members are bound to give this
EN 115-1 the status of a National Standard without any national deviations.
The following countries are CEN Members:
Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,
Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain,
Sweden, Switzerland, Turkey and the United Kingdom.
5.1.1.2 What is the code (law, standard, requirement)?
The purpose of EN 115 is to define minimum safety requirements in order to reduce the possibility of
accidents on escalators and moving walks.
The harmonized standard is essentially a method of demonstrating compliance with the essential
safety requirements of the machinery directive which is embodied in the laws of each country member
of CEN/CENELEC and therefore, demonstrates compliance with the laws of the member states.

---------------------- Page: 8 ----------------------
ISO/TR 14799-2:2023(E)
5.1.1.3 Is EN 115-1 a compulsory standard?
Some exceptions are possible (such as section 1).
5.1.1.4 Is EN 115-1 a technical description, a requirement, or a recommendation?
Conformity with EN 115-1 is one way to satisfy the requirements of the European Machinery Directive.
5.1.1.5 Is EN 115-1 a performance or a design standard?
EN 115-1 has to be considered as a minimum requirement for safe operation of escalators and moving
walks.
5.1.2 North American Standard A17.1/B44
5.1.2.1 Rationale for A17.1/B44
A17.1/B44 is intended to enhance public health and safety. It serves as the basis for state, municipal, and
other jurisdictional authorities in drafting regulations governing the installation, testing, inspection,
maintenance, alteration, and repair of elevators, dumbwaiters, escalators, moving walks, material
lifts with automatic transfer devices, wheelchair lifts, and stairway chair lifts. It is also intended as
a standard reference of safety requirements for the guidance of architects, engineers, insurance
companies, manufacturers, and contractors, and as a standard of safety practices for owners and
managements of structures where equipment covered in the scope of the code is used.
5.1.2.2 What is the code (law, standard, requirement)?
The A17.1/B44 Safety Code for Elevators and Escalators is a voluntary reference standard that is used
by people and organizations involved in the industry. Developed by a consensus of experts in the
industry, it is used to guide them in maintaining a high level of safety in their respective functions.
After it is developed by the ASME under the auspices and consensus procedures established by ANSI, it
becomes an American National Standard.
5.1.2.3 Is A17.1/B44 a compulsory standard?
As published, A17.1/B44 is a voluntary standard. It is used by authorities having jurisdiction as a basis
for the code they enforce and becomes law when the governing legislative body over their jurisdiction
adopts it.
5.1.2.4 Is A17.1/B44 a technical description, a requirement, or a recommendation?
A17.1/B44 presents most of its requirements as mandatory when following the standard. However,
some rules can be in the form of a permissive recommendation.
5.1.2.5 Is A17.1/B44 a performance or a design standard?
The A17.1/B44 code is developed as a performance standard under the procedures established by the
ASME and the CSA. Due to the unique nature of the industry, some rules are of a design nature, but
efforts are continually underway to replace them with performance language.
5.1.3 Japanese codes
5.1.3.1 Rationale for Japanese codes?
The Japanese codes are established to protect life, health, and property of the nation, and thereby, to
contribute to promoting public welfare.

---------------------- Page: 9 ----------------------
ISO/TR 14799-2:2023(E)
5.1.3.2 What is the code (law, standard, requirement)?
The codes consist of four kinds of laws (BSLJ, BSLJ-EO, MOC-N, and EUIL-MO) and three kinds of
standards (JIS, JEAS, and JEAC).
5.1.3.3 Are the Japanese codes compulsory standards?
The Japanese codes are compulsory standards.
5.1.3.4 Are the Japanese codes a technical description, a requirement, or a recommendation?
The Japanese codes are technical descriptions, requirements, and recommendations.
5.1.3.5 Are the Japanese codes performance or design standards?
The Japanese codes are considered as performances and design standards.
5.2 General — Technical basis and structure of standards
Table 2 shows the abbreviated comparison and comments of worldwide escalator and moving walk
safety standards. In Table 2, all comments from the ISO/TC 178/WG 5 are shown in italics. Reference to
a table or figure refers to information from ISO/TR 14799-1 as well as to the original codes.
The following logic for the structure of comments is applied:
— Remark: to give clarification (Remark is equal to Note)
— Agreed upon: general acceptance of the consensus
— Fundamental differences: no possibility to find a consensus (e.g. caused by national building codes
and regulations)
— Worldwide acceptance: giving the values today which fulfil all three codes

Introduction
This document is intended to aid standards writers in developing their safety requirements and to help
standards users understand the basis for the requirements as they are applied throughout the world.
This document is not intended to replace existing safety standards which can have been updated.
Conclusions are arrived at in some cases, but only where is unanimity amongst the various experts. In
other cases, the reasons for the divergent views are expressed.
This document is to be read in conjunction with the various safety standards. Unless approved by the
relevant standard writing organizations, the information contained in this Technical Reportdocument
does not necessarily represent the opinions of these standards writing organizations.
TheThis document was done with EN 115-1:2017 as a reference document shown as the only one in its
normal sequence. All other codes are not in their normal sequence and logical order. They are structured
differently to EN 115-1:2017. The result incorrectly leaves the impression of incompleteness of these
standards. These standards in their original structure inclusive of their references to other standards and
requirements are however complete.
This comparison does no longer includeincludes the Australian, Korean, and Russian safety codes as there
are intentions on national level to bring theses codes in line with one of the remaining three codes.
Due to copyright issues, A17.1-2016/CSA B44-16 (North America) detailed text comparison is not
covered in this document.
Due to copyright restrictions, in this document there is no code text of ASME A17.1/B44:2016 available,
only references to relevant sections and clause numbers are made. The leading standard for the
comparison is EN 115-1:2017. The numbering sequence of the first column follows the EN 115-1:2017
structure.
It is to be noted that inIn addition to the compared standards and other regulations, escalators and
moving walks can be required to conform to the requirements of other standards, as appropriate.

7.15.1 Historical origin and development of standards
7.1.15.1.1 European Standard EN 115-1
7.1.1.15.1.1.1 Rationale for EN 115-1
The ever-increasing number of escalators put in operation in Europe after the second world war required
the drawing-up of guidelines for models and safety for escalators, especially as not all European countries
had their own standard or national regulation for escalators.

---------------------- Page: 9 ----------------------
ISO/DTR 14799-2:2022(E)
Therefore, specialists/experts from the European countries joined together and developed the first draft
of EN 115, which was accepted by CEN on 3rd January 1995 which has been continuously developed since
then. The last complete revised document was published in 2017
According to the Internal Regulations of CEN/ CENELEC, the CEN members are bound to give this
EN 115-1 the status of a National Standard without any national deviations.
The following countries are CEN Members:
Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany,
Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden,
Switzerland, Turkey and the United Kingdom.
7.1.1.25.1.1.2 What is the code (law, standard, requirement)?
The purpose of EN 115 is to define minimum safety requirements in order to reduce the possibility of
accidents on escalators and moving walks.
The harmonized standard is essentially a method of demonstrating compliance with the essential safety
requirements of the machinery directive which is embodied in the laws of each country member of
CEN/CENELEC and therefore, demonstrates compliance with the laws of the member states.
7.1.1.35.1.1.3 Is EN 115-1 a compulsory standard?
Some exceptions are possible (such as section 1).
7.1.1.45.1.1.4 Is EN 115-1 a technical description, a requirement, or a recommendation?
ComplianceConformity with EN 115-1 is one way to satisfy the requirements of the European Machinery
Directive.
7.1.1.55.1.1.5 Is EN 115-1 a performance or a design standard?
EN 115-1 has to be considered as a minimum requirement for safe operation of escalators and moving
walks.
7.1.25.1.2 North American Standard A17.1/B44
7.1.2.15.1.2.1 Rationale for A17.1/B44
A17.1/B44 is intended to enhance public health and safety. It serves as the basis for state, municipal, and
other jurisdictional authorities in drafting regulations governing the installation, testing, inspection,
maintenance, alteration, and repair of elevators, dumbwaiters, escalators, moving walks, material lifts
with automatic transfer devices, wheelchair lifts, and stairway chair lifts. It is also intended as a standard
reference of safety requirements for the guidance of architects, engineers, insurance companies,
manufacturers, and contractors, and as a standard of safety practices for owners and managements of
structures where equipment covered in the scope of the code is used.
7.1.2.25.1.2.2 What is the code (law, standard, requirement)?
The A17.1/B44 Safety Code for Elevators and Escalators is a voluntary reference standard that is used by
people and organizations involved in the industry. Developed by a consensus of experts in the industry,
it is used to guide them in maintaining a high level of safety in their respective functions.

---------------------- Page: 10 ----------------------
ISO/DTR 14799-2:2022(E)
After it is developed by the ASME under the auspices and consensus procedures established by ANSI, it
becomes an American National Standard.
7.1.2.35.1.2.3 Is A17.1/B44 a compulsory standard?
As published, A17.1/B44 is a voluntary standard. It is used by authorities having jurisdiction as a basis
for the code they enforce and becomes law when the governing legislative body over their jurisdiction
adopts it.
7.1.2.45.1.2.4 Is A17.1/B44 a technical description, a requirement, or a recommendation?
A17.1/B44 presents most of its requirements as mandatory when following the standard. However, some
rules can be in the form of a permissive recommendation.
7.1.2.55.1.2.5 Is A17.1/B44 a performance or a design standard?
The A17.1/B44 code is developed as a performance standard under the procedures established by the
ASME and the CSA. Due to the unique nature of the industry, some rules are of a design nature, but efforts
are continually underway to replace them with performance language.
7.1.35.1.3 Japanese codes
7.1.3.15.1.3.1 Rationale for Japanese codes?
The Japanese codes are established to protect life, health, and property of the nation, and thereby, to
contribute to promoting public welfare.
7.1.3.25.1.3.2 What is the code (law, standard, requirement)?
The codes consist of four kinds of laws (BSLJ, BSLJ-EO, MOC-N, and EUIL-MO) and three kinds of
standards (JIS, JEAS, and JEAC).
7.1.3.35.1.3.3 Are the Japanese codes compulsory standards?
The Japanese codes are compulsory standards.
7.1.3.45.1.3.4 Are the Japanese codes a technical description, a requirement, or a
recommendation?
The Japanese codes are technical descriptions, requirements, and recommendations.
7.1.3.55.1.3.5 Are the Japanese codes performance or design standards?
The Japanese codes are considered as performances and design standards.
7.25.2 General — Technical basis and structure of standards
Table 2 shows the abbreviated comparison and comments of worldwide escalator and moving walk
safety standards. AllIn Table 2, all comments in table 2 from the ISO/TC 178/WG 5 are shown in
italicitalics. Reference to a table or figure refers to information from ISO/TR 14799-1 as well as to the
original codes.
FollowingThe following logic for the structure of comments is applied:
•— Remark: to give clarification (Remark is equal to Note)
•— Agreed upon: general acceptance of the consensus

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
This document is intended to aid standards writers in developing their safety requirements and to help
standards users understand the basis for the requirements as they are applied throughout the world.
This document is not intended to replace existing safety standards which can have been updated.
Conclusions are arrived at in some cases, but only where is unanimity amongst the various experts. In
other cases, the reasons for the divergent views are expressed.
This document is to be read in conjunction with the various safety standards. Unless approved by
the relevant standard writing organizations, the information contained in this document does not
necessarily represent the opinions of these standards writing organizations.
This document was done with EN 115-1:2017 as a reference document shown as the only one in its
normal sequence. All other codes are not in their normal sequence and logical order. They are structured
differently to EN 115-1:2017. The result incorrectly leaves the impression of incompleteness of these
standards. These standards in their original structure inclusive of their references to other standards
and requirements are however complete.
This comparison no longer includes the Australian, Korean, and Russian safety codes as there are
intentions on national level to bring theses codes in line with one of the remaining three codes.
Due to copyright issues, A17.1-2016/CSA B44-16 (North America) detailed text comparison is not
covered in this document.
Due to copyright restrictions, in this document there is no code text of ASME A17.1/B44:2016 available,
only references to relevant sections and clause numbers are made. The leading standard for the
comparison is EN 115-1:2017. The numbering sequence of the first column follows the EN 115-1:2017
structure.
In addition to the compared standards and other regulations, escalators and moving walks can be
required to conform to the requirements of other standards, as appropriate.

5 Basis for escalator and moving walk safety standards
5.1 Historical origin and development of standards
5.1.1 European Standard EN 115-1
5.1.1.1 Rationale for EN 115-1
The ever-increasing number of escalators put in operation in Europe after the second world war
required the drawing-up of guidelines for models and safety for escalators, especially as not all
European countries had their own standard or national regulation for escalators.
Therefore, specialists/experts from the European countries joined together and developed the
first draft of EN 115, which was accepted by CEN on 3rd January 1995 which has been continuously
developed since then. The last complete revised document was published in 2017
According to the Internal Regulations of CEN/ CENELEC, the CEN members are bound to give this
EN 115-1 the status of a National Standard without any national deviations.
The following countries are CEN Members:
Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,
Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain,
Sweden, Switzerland, Turkey and the United Kingdom.
5.1.1.2 What is the code (law, standard, requirement)?
The purpose of EN 115 is to define minimum safety requirements in order to reduce the possibility of
accidents on escalators and moving walks.
The harmonized standard is essentially a method of demonstrating compliance with the essential
safety requirements of the machinery directive which is embodied in the laws of each country member
of CEN/CENELEC and therefore, demonstrates compliance with the laws of the member states.

---------------------- Page: 8 ----------------------
ISO/DTR 14799-2:2023(E)
5.1.1.3 Is EN 115-1 a compulsory standard?
Some exceptions are possible (such as section 1).
5.1.1.4 Is EN 115-1 a technical description, a requirement, or a recommendation?
Conformity with EN 115-1 is one way to satisfy the requirements of the European Machinery Directive.
5.1.1.5 Is EN 115-1 a performance or a design standard?
EN 115-1 has to be considered as a minimum requirement for safe operation of escalators and moving
walks.
5.1.2 North American Standard A17.1/B44
5.1.2.1 Rationale for A17.1/B44
A17.1/B44 is intended to enhance public health and safety. It serves as the basis for state, municipal, and
other jurisdictional authorities in drafting regulations governing the installation, testing, inspection,
maintenance, alteration, and repair of elevators, dumbwaiters, escalators, moving walks, material
lifts with automatic transfer devices, wheelchair lifts, and stairway chair lifts. It is also intended as
a standard reference of safety requirements for the guidance of architects, engineers, insurance
companies, manufacturers, and contractors, and as a standard of safety practices for owners and
managements of structures where equipment covered in the scope of the code is used.
5.1.2.2 What is the code (law, standard, requirement)?
The A17.1/B44 Safety Code for Elevators and Escalators is a voluntary reference standard that is used
by people and organizations involved in the industry. Developed by a consensus of experts in the
industry, it is used to guide them in maintaining a high level of safety in their respective functions.
After it is developed by the ASME under the auspices and consensus procedures established by ANSI, it
becomes an American National Standard.
5.1.2.3 Is A17.1/B44 a compulsory standard?
As published, A17.1/B44 is a voluntary standard. It is used by authorities having jurisdiction as a basis
for the code they enforce and becomes law when the governing legislative body over their jurisdiction
adopts it.
5.1.2.4 Is A17.1/B44 a technical description, a requirement, or a recommendation?
A17.1/B44 presents most of its requirements as mandatory when following the standard. However,
some rules can be in the form of a permissive recommendation.
5.1.2.5 Is A17.1/B44 a performance or a design standard?
The A17.1/B44 code is developed as a performance standard under the procedures established by the
ASME and the CSA. Due to the unique nature of the industry, some rules are of a design nature, but
efforts are continually underway to replace them with performance language.
5.1.3 Japanese codes
5.1.3.1 Rationale for Japanese codes?
The Japanese codes are established to protect life, health, and property of the nation, and thereby, to
contribute to promoting public welfare.

---------------------- Page: 9 ----------------------
ISO/DTR 14799-2:2023(E)
5.1.3.2 What is the code (law, standard, requirement)?
The codes consist of four kinds of laws (BSLJ, BSLJ-EO, MOC-N, and EUIL-MO) and three kinds of
standards (JIS, JEAS, and JEAC).
5.1.3.3 Are the Japanese codes compulsory standards?
The Japanese codes are compulsory standards.
5.1.3.4 Are the Japanese codes a technical description, a requirement, or a recommendation?
The Japanese codes are technical descriptions, requirements, and recommendations.
5.1.3.5 Are the Japanese codes performance or design standards?
The Japanese codes are considered as performances and design standards.
5.2 General — Technical basis and structure of standards
Table 2 shows the abbreviated comparison and comments of worldwide escalator and moving walk
safety standards. In Table 2, all comments from the ISO/TC 178/WG 5 are shown in italics. Reference to
a table or figure refers to information from ISO/TR 14799-1 as well as to the original codes.
The following logic for the structure of comments is applied:
— Remark: to give clarification (Remark is equal to Note)
— Agreed upon: general acceptance of the consensus
— Fundamental differences: no possibility to find a consensus (e.g. caused by national building codes
and regulations)
— Worldwide acceptance: giving the values today which fulfil all three codes

frequency and nominal voltage.
REMARK: All codes have in common, that the speed definition is one of the design parameters for the escalator/moving walk.
FUNDAMENTAL DIFFERENCES: In each code speed is named differently. EN 115-1 and JIS define the speed under no load condi-
tion where A17.1 defines speed under rated load condition.
