5 History of Metrology
➢ Ancient Egypt: (3000 years BC): The first royal cubit was defined as the length of the forearm from elbow to tip of the extended middle finger of the ruling Pharaoh, plus the width of his hand.
➢ The Roman Mile
➢ Medieval Metrics
➢ Defining the Metre

1. The definition of internationally accepted units of measurement, e.g. the metre.
2. The realisation of units of measurement by scientific methods, e.g. the realization of a metre
through the use of lasers.
3. The establishment of traceability chains by determining and documenting the value and accuracy of a measurement and disseminating that knowledge, e.g. the documented relationship between the micrometer screw in a precision engineering workshop and a primary laboratory for optical length metrology.

12 The traceability “chain”
Slide courtesy Dr S Davidson, NPL, UK 13 Role of Metrology
The world economy, society and citizens depend on the international “quality infrastructure” which depends on metrology. Metrology provides: – Measurements that are stable … comparable … and coherent. These are provided by chains of traceability based on the work of the National Metrology Institutes (NMIs).
14 Quality Infrastructure
Quality Infrastructure
15 Building blocks of the QI
Societal concerns Health, Safety. Environment. Economic wellbeing, Fair trade, consumer protection, regulation
Standardization Metrology Conformity Accreditation Pre and post assessment market surveillance Development of Measurement and testing inspection international and Traceability certification SDOC national standards
Business concerns Trading, quality, profitability, distribution, purchasing use of specifications and contracts.

The term “tolerance” should not be used to designate ‘maximum permissible error’.

21 Measurements terminologies important to understand Calibration
“Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties, and in a second step, uses this information to establish a relation for obtaining a measurement result from an indication ” International Vocabulary of Metrology ) ( JCGM 200:2012 – International Vocabulary of Metrology )

An effective measurement management system ensures that measuring equipment and measurement processes are fit for their intended use and is important in achieving product quality objectives and managing the risk of incorrect measurement results. The objective of a measurement management system is to manage the risk that measuring equipment and measurement processes could produce incorrect results affecting the quality of an organization’s product.
27 Risk of calibration program failure Decisions are made after measurements !!
Quality Safety Cost
Measurement instrument Decisions are made based on facts. Properly calibrated equipment deviate by time and usage. Measurement is part of these facts. means less waste. Less waste Calibration identifies the Measurement instrument produces means costs are kept low and deviation to correct the reading proper result if they are properly margins aren’t negatively controlled by calibration program affected. Who is right? … Who is wrong?
