Metrology is the study of measurements, with various fields such as electromagnetic, chemical, and mechanical metrology. The International Organization of Legal Metrology was created in 1955 to unify manufacturing and commercial activities worldwide. Having unified metrics helps keep the market competitive and ensures products can be used globally. Metrology conventions are becoming popular for sharing ideas and concerns. Standardization of measurements helps keep repair costs competitive and allows customers to purchase products from any country.
Metrology is the scientific study of measurements. Measurements come in all forms. Gemstones can be measured by hardness or carat. Pieces of wood can be measured in length. Electricity can be measured in amperes, volts and watts.
As early as the 1950s, companies around the world determined that it was necessary to bring the unit to measurement in the manufacturing process. As a result, the International Organization of Legal Metrology was created in 1955. Today, dozens of countries are members of the organization and share a common goal, to unify manufacturing and commercial activities around the world.
With so many countries competing for market share of manufacturing activity, metrology is essential to keep the market competitive. Having unified metrics can help with future repair costs and ensure that products can be used around the world without difficulty. Many organizations hold international conferences where metrology members can share ideas and concerns and compare notes. These metrological conventions are becoming a popular means of unifying the wide range of measurements used around the world.
Members of electromagnetic metrology spend their time unifying measurements of radio waves, temperature, humidity, radioactivity, DC frequency, fiber optics, photometry, and ionizing radiation. Those involved in electromagnetic metrology work to create a unified version of electric currents and voltages. Without electromagnetic metrology, each country that makes parts for electronic equipment would use different electrical measurements. Products break easily or don’t work. Accurate temperature and humidity measurements are also required to avoid wasting energy in heating and cooling products.
Over the past decade, there has been an increased need for metrology in chemistry laboratories. The metrology of chemistry makes it possible to create robust processes for quality control of many products manufactured around the world. With the increase in pollution controls, there is an acute need to regulate emission controls worldwide. Metrology of chemistry helps ensure that different countries use chemicals in a way that protects the environment. Chemical metrology helps define standards for use in gas/air mixtures, gas analyzers, inorganic materials, spectrometry, and microanalysis.
Mechanical metrology focuses on the standardization of acoustics, force/pressure, vibration, volume, density and dimensions. As Asian companies begin to conquer the country in terms of low-cost manufacturing, other companies are relying on mechanical metrology to help them compete. With a set of standards in place, customers can purchase products from any country and know they will be receiving universally sized parts. This helps keep repair costs competitive.
