The OIML Basic Certificate System
The OIML Basic Certificate System for Measuring Instruments was introduced in 1991 to facilitate administrative procedures and lower the costs associated with the international trade of measuring instruments subject to legal requirements. The System, which was initially called the “OIML Certificate System”, is now called the “OIML Basic Certificate System”. The aim is for “OIML Basic Certificates of Conformity” to be clearly distinguished from “OIML MAA Certificates”. The System provides the possibility for manufacturers to obtain an OIML Basic Certificate and an OIML Basic Evaluation Report (called “Test Report” in the appropriate OIML Recommendations) indicating that a given instrument type complies with the requirements of the relevant OIML International Recommendation. An OIML Recommendation can automatically be included within the System as soon as all the parts – including the Evaluation Report Format – have been published. Consequently, OIML Issuing Authorities may issue OIML Certificates for the relevant category from the date on which the Evaluation Report Format was published; this date is now given in the column entitled “Uploaded” on the Publications Page. Other information on the System, particularly concerning the rules and conditions for the application, issue, and use of OIML Certificates, may be found in OIML Publication B 3 OIML Basic Certificate System for OIML Type Evaluation of Measuring Instruments (Edition 2011) which may be downloaded from the Publications page of the OIML web site.

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:
- Unscheduled downtime
- 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.
