Force and Weight Measurement Re-
sources
The process of measuring the size of weight or force dates back as far as
3500 BC where the Ancient Egyptians civilization adapted a tool called
“The Equal Arm Balance”.
Over the years, force and weight measurement has evolved to become part
and parcel of domestic, commercial and industrial applications and other
fields of applications with the invention of various modern force and weight
measurement instruments by different Original Equipment Manufacturers
(OEMs).
There have been improvements in the precision of these instruments and
many job roles have been created. This article contains several resource
guides of different categories and you will find the necessary information
about various force and measurement instruments and their general appli-
cations, OEMs, Certification standards and markings, career openings and
more.
FORCE AND WEIGHT MEASURE-
MENT – INSTRUMENTS
These are instruments that are used to create measurement solutions for
various fields of applications. Each of the instruments has diverse applica-
tions possibilities and some are also designed for specific applications. The
following are the basic force and weight measurement instruments which
for the basis of load cells, torque transducers, scales and others;

2. This section of the guide shows below the various certification standards
and markings.
 ISO: ISO stands for the International Organization for Standardiza-
tion. It develops and publish international standards. It should be
noted that ISO does not provide certification or conformity assess-
ment for products and instruments. Some of the popular ISO stand-
ards are ISO 9001 Quality management, ISO 14001 Environmental
management and ISO/IEC 27001 Information security management.
Use this resource to navigate information about other popular stand-
ards that relate to force and measuring instruments.
 RoHS: RoHS stands for Restriction of Hazardous Substances. The
RoHS restricts the use of hazardous materials found in electrical and
electronic products. All applicable electrical or electronic products,
equipment, sub-assemblies, cables, components, or spare parts in
the European Union market must pass RoHS compliance. The RoHS
specifies maximum levels for some restricted substances such as
Lead, Mercury, Cadmium, Hexavalent Chromium and many more.
Follow this resource to see the various RoHS steps to certification,
RoHS product categories and restricted substances.
 CE: These letters CE are the abbreviation of the French phrase
“Conformité Européene” which means “European Conformity” in Eng-
lish. This marking shows that the product complies with the require-
ments of the relevant European health, safety and environmental pro-
tection legislation. Discover the importance of a CE marking, the gen-
eral principles of the CE marking, what products need CE marking,
how to obtain the CE marking and many more.
 NTEP: NTEP is the abbreviation for National Type Evaluation Pro-
gram and it requires various original equipment manufacturers and
industries to submit their prototype weighing devices for evaluation
so as to if it meets the uncertainties that are related to tolerances as-
sociated with the intended final use in the marketplace. Learn more
about the NTEP program by using this resource.

3.  OIML: It stands for International organization of Legal metrology. Le-
gal metrology can be defined as the application of legal requirements
to measurements and measuring instruments, hence the basic role of
the OIML is to create global standards for use in legal metrology leg-
islation. Discover the mission of OIML, the issues of OIML, the vari-
ous international systems, the new OIML certification systems,
emerging metrology systems and many more through this resource.
It should be noted that there are other certification bodies that approves the
use and sales of force and weight measurement instruments.
Examples of the ones not mentioned above are American National Stand-
ards Institute (ANSI), American Association for Laboratory Accredita-
tion (A2LA), National Supervision and Inspection Center for Explosion Pro-
tection and Safety of Instrumentation (NEPSI), International Aerospace
Quality Group (IAQG), Underwriters Laboratories (UL), Canadian Stand-
ards Association (CSA) and many more.
Most standards are based on the country where the product is to be used
while some standard bodies have global reach of influence on different
products.
