GOLDEN JUBILEE CELEBRATIONS OF METRIC SYSTEM IN INDIA
“Legal Metrology – Achievements of India and what it can offer to others.”
Sri P.A Krishnamurthy,
Former Director, Legal Metrology, Government of India.
The field of ‘Legal Metrology’ or Weights and Measures’ as is known in the common parlance, is the field where measurements are regulated by Government laws for the benefit of all stakeholders. The main object of such regulation is to ensure standardized procedures for calibration acceptable to all stakeholders, transparency in the whole procedure, and accountability of the measurement results.

A calibration certificate reports results at the time the calibration was performed. In many cases, the responsible person assumes that the calibration is valid for a year. This leads to the wrong conclusion that a calibration interval of one year is sufficient.
Ideally, calibration intervals are defined following a risk-based methodology, for example, what is the probability of something going wrong and how high is the impact? A high impact and high probability correspond to a high risk, which requires a shorter calibration interval. Otherwise, a low impact and a low probability result in a low risk, allowing intervals to be extended.
To forgo calibration is a high-risk strategy. Hidden costs and risks associated with the un-calibrated balance or scale could be much higher than the cost of calibration itself. Using non-calibrated equipment can lead to production problems such as:
Inferior product quality
Process and audit issues
Product rework and recalls
Environmental changes can also lead to undetected drift or increasing random errors that degrade performance. Periodically scheduled calibration along with routine testing (see below) is the best way to reduce calibration-related risk.
SWPI has been engaged in manufacturing exclusively Weights since 1961.
The scenario of the world is changing very rapidly due to revolutionary development in the field of Science & Technology. It has brought a marked change in the requirement of quality weights of various specifications, shapes, sizes, designs, accuracy class, etc.
Why would you want to weigh at all if your balance is not calibrated?
Balance or scale calibration is essential to achieve accurate weighing results. Ignoring this important service activity turns to measure into guesswork. In other words, it is negligent to weigh with a non-calibrated balance or scale.
