In our collaboration with the IEEE Education & Healthcare Facilities Committee we are sensitive to the point of view of our research and standards setting colleagues in other nations; among them CEN (European Committee for Standardization) and CENELEC (European Committee for Electrotechnical Standardization) are two standardization organizations in Europe, and they have some similarities and differences.

  • CEN develops standards for a wide range of products, services, and processes, including construction, consumer goods, food and agriculture, and many others.
  • CENELEC, on the other hand, focuses specifically on electrotechnical standards, including electrical equipment, electronic components, and telecommunications.

Another key difference between CEN and CENELEC is their membership. CEN has members from 34 European countries, including national standardization bodies, industry associations, and consumer organizations. CENELEC has members from 34 European countries as well, but they are limited to national electrotechnical committees, which are responsible for electrotechnical standardization in their respective countries.

Despite their differences, both CEN and CENELEC play important roles in the development and promotion of European standards, and their standards are widely recognized and used across Europe and beyond.  Its leadership committees meet this week in Brussels. CLICK HERE to access videolinks.

Technical Barriers to Trade

World According to Marco Polo

 

We track action in international administrative procedures that affect the safety and sustainability agenda of the education facility industry.  From time to time we find product purchasing contracts that contain “boilerplate” requiring conformity to applicable regulations found in the Agreement on Technical Barriers to Trade (TBT).   Common examples are found in contracts for the acquisition of information technology and specialty laboratory equipment.

The World Trade Organization TBT Agreement obliges all Parties  to maintain an inquiry point that is able to answer questions from interested parties and other WTO Members regarding technical regulations, standards developed by government bodies, and conformity assessment procedures, as well as provide relevant documents.  The TBT Agreement also requires that WTO Members notify the WTO of proposed technical regulations and conformity assessment procedures so interested parties can become acquainted with them and have an opportunity to submit written comments.

Technical Barriers to Trade Information Management System

The inquiry point and notification authority for the United States is operated by the National Institute of Standards and Technology an agency within the U.S. Department of Commerce.  We provide a link here for the convenience of faculty, specifiers and purchasing professionals.

We include the TBT on the agenda of our Hello World! colloquium; open to everyone.  See our CALENDAR for the next online meeting.

Grant Hafner

IEEE 1863-2019 Guide for Overhead AC Transmission Line Design covers basic principles, methods and experience for designing of 110 kV to 1000 kV AC overhead transmission lines, and may also be used as reference for the design of lower voltage overhead transmission lines. This Guide consists of the introduction, definitions, meteorological design criteria, electrical design, structural design criteria, design of foundations, and experiment result and design experience.

This Guide is a listing of the information and procedure that is required during the design of AC transmission line, and provides guidance for transmission line designers in data collection and design stage.

January 1st is Polar Bear Plunge Day in the Great Lakes.  It is also popular among the young in other “watery” universities around the world.

Pleasures and Hazards

Pleasures:

  1. Increased adrenaline rush: Cold water swimming can produce a surge of adrenaline in the body, which can make you feel more energized and alert.
  2. Improved mood: Cold water swimming has been associated with an increased release of endorphins, which can elevate your mood and reduce stress levels.
  3. Improved immune function: Cold water swimming has been shown to improve immune function, possibly due to the stress response induced by the cold water.
  4. Sense of accomplishment: Many people find ice swimming to be a challenging and rewarding experience, providing a sense of accomplishment and pride.
  5. Social bonding: Ice swimming can be a social activity, with groups of people coming together to share the experience and support each other.

Hazards:

  1. Hypothermia: Prolonged exposure to cold water can cause hypothermia, which can be life-threatening if left untreated.
  2. Cold shock response: Entering cold water can cause an involuntary gasp reflex, which can lead to drowning if it occurs while the head is underwater.
  3. Heart problems: Cold water swimming can put a strain on the heart and increase the risk of heart attack or stroke in people with underlying cardiovascular disease.
  4. Frostbite: Exposed skin can become frostbitten in cold water, particularly in extremities such as the fingers and toes.
  5. Injury from slipping or falling: Ice swimming can be hazardous if proper safety precautions are not taken, such as wearing appropriate footwear and using a rope or ladder to enter and exit the water.

Campus Bulk Electrical Distribution

College and university campuses distribute electric energy in tranches of 10 to 250 megawatts; typically at voltages above 1000 VAC and are generally regarded as load-side services (or regulated utility customers). Two fairly stable sections of the National Electrical Code set the standard of care for these systems — Part III of Article 110 and Article 495.

We will examine them during today’s High Voltage Electric Service colloquium.

FREE ACCESS: 2023 National Electrical Code

We collaborate closely with the IEEE Education & Healthcare Facilities Committee which meets online 4 times per month in European and American time zones.  Ahead of the August 2024 public comment deadline we will examine transcripts of technical action on this topic:
