1. International trends in codes and standards Affecting high speed lifts
China Elevator Association Seminar
_09
CEN/TC 10 (Esfandiar Gharibaan)

2. International standardization trends Background
Every lift must comply with the relevant National codes and standards
before putting into service
to remain in operation during its life time
National standards
developed by the National standards body, or
adoption of the International standards
International standards
reflect the currently available state of the art
harmonize safety and technical requirements

3. International standardization trends Background
Developed by CEN, CENELEC, ISO, IEC
participation and approval of the National standards bodies, e.g. SAC, ASME, BSI, DIN
16,000 CEN and 15,000 ISO standards in use
76 specific standards for lifts and escalators
> 500 International standards may be applicable for lifts and escalators, covering
electrical and mechanical design
material selection
reliability and quality
testing methods and verification

4. Specific needs of high speed lifts (and tall buildings)

5. International standardization trends High speed lifts/tall buildings
High speed lifts present specific challenges
need for detailed traffic planning
possible use of lifts for evacuation of the building
higher specification for noise and ride comfort
building design issues
building sway
piston effect in the lift well (lift car pushing the air)
stack effect (difference in air density in the height of the building)

6. International standardization trends High speed lifts/tall buildings
Current International safety standards for lifts impose no limitation of speed or travel height
Several standards address the challenges for high speed lifts (tall buildings)
However, current standardization trends may have an impact on the high speed lifts

7. Standardisation trends Safety

8. Standardization trends: Safety Continuous update
Continuous update of safety requirements, from
experience shared from around the world
safety of passengers and workers
life cycle of the lift, including maintenance
change in safety concepts and lower tolerance for risks
systematic evaluation of the potential risks, for example using ISO standard

9. Standardization trends: Safety Recent changes
Examples of safety related changes EN 81-20/-50
higher strength of the landing and car doors
preventing car door striking the passengers
preventing fall into the lift well due to self-rescue
preventing fall into the lift well when unlocking the landing door
easier access to the car components from the pit
improved access to pit and other working areas

10. Standardisation trends Harmonisation of safety requirements

11. Standardization trends: Harmonization of safety Cooperation of standardization organizations
Cooperation CEN, SAC, ISO, ASME and JISC
collect experience and needs around the world
achieve common understanding of the safety risks
agree on common solutions to remove the risks
agree on common safety requirements
achieve higher level of harmonization of the safety requirements around the world
improving safety for all

12. Standardization trends: Harmonization of safety Close cooperation SAC/TC 196 and CE/TC 10
Close cooperation SAC/TC 196 and CEN/TC 10
Technical exchange since early 2000s
Cooperation agreement signed in 2005
Regular technical exchange meetings
Partnership in developing EN 81-20/-50
Close cooperation in developing other standards

13. Standardization trends: Harmonization of safety Cooperation agreement SAC/TC 196 and CEN/TC 10

14. Standardization trends: Harmonization of safety Use of EN 81-1 (EN 81-20/-50) around the world
EN 81-20/-50: example of safety harmonization
EN 81-20: result of revision of EN 81-1
Use of EN 81-1 in countries around the world
adopted as identical national standards, or
used as the basis for national standards but with some national differences, or
the “basic” requirements for the national standards, or
accepted beside other international standards
Result of effort from experts all around the world

15. Standardization trends: Harmonization of safety Use of EN 81-1 (EN 81-20/-50) around the world

16. Standardization trends: Harmonization of safety Next step
EN 81-20/-50 to become EN ISO standards
ISO is in process adopting EN 81-20/-50
ISO standards will be identical to EN 81-20/-50
Expected publication: December 2017
Adoption by ISO as identical standards
A giant step in harmonization of safety requirements around the world

17. Standardisation trends Evacuation using lifts

18. Standardization trends: Evacuation using lifts Growing need
Since year 2000
3-4 time more buildings with 200m height
nearly 100 buildings are added every year
Lifts made easy access for all
including persons with disability
In emergency, 80% of a tall building occupants
prefer using lifts to exit the building
Evacuation of a building with occupants
may take > 2 hours using stairs, or
~30 minutes with properly planned lifts

19. Standardization trends: Evacuation using lifts Standards for lifts
ISO TS 18870:2014
lifts used to assist in building evacuation
for all occupants
with automatic control
CEN/TS 81-76:2011
evacuation of disabled persons using lifts
for disabled persons
assisted evacuation
ASME A17.1:2013
Occupant Evacuation Operation (OEO)

20. Standardization trends: Other fire related issues Standards for lifts
fire resistance test of the landing doors
based on tracer gas principles
being revised and updated
ISO :2014
same principles as EN 81-80
fire rating classification to be added in the near future
EN 81-72:2015
firefighters lift
updated and published in 2015

21. Standardisation trends Energy efficiency

22. Standardization trends: Energy efficiency Energy efficiency for buildings
Buildings consume 40% of total energy in the world
Introduction of national energy efficiency regulations for buildings and products
Introduction of initiatives for energy performance of buildings
such as: LEED, BREEAM, ENERGY STAR
Lifts consume 5-8% of the energy in a building
Energy performance of systems in buildings is improving rapidly

Proper planning and selection of type, speed, size and number of lifts is crucial for
providing adequate transport capacity
optimizing waiting time for users

optimizing emergency efficiency
if lifts are used for evacuation of the building
providing availability and capacity
