Regulations

Metrology is the science that studies measurement, having as one of its purposes to ensure the quality of products and services, through the control of measurement equipment used by the industry and that are present in several eveyday actions, such as:

⦁ Car fueling, with the volume reference (L);

⦁ Food purchases by weight (Kg);

⦁ Electricity consumption in Watts (W);

⦁ Water consumption (L/m³).

Because it is directly linked to consumer relations, and even before they are commercialized, the measuring instruments or systems must go through a set of conformity assessment procedures, defined in specific metrological regulations, and that are designed to ensure compliance with the applicable technical requirements.

Even after approval, there is a need for periodic evaluations of these instruments, to ensure that the technical requirements remain the same as the current regulations. This whole set of activities is established by INMETRO as Legal Metrological Control.

Any legal entity located in Brazil that develops activities of production, assembly, creation, construction, transformation, import, export, distribution, or commercialization of measurement instruments can apply for model approval.

All the general procedures and criteria for the Model Evaluation process are established in the Inmetro Administrative Rule nº 200/2021, while the NIE-DIMEL-013 standard presents details on each step of the Model Approval.

The advance of technology has brought significant changes to various sectors of society, causing major impacts on the economy and business. Metrology has closely felt the reflexes of this rapid evolution with the development of ever more complete and sophisticated Measuring Instruments.

Besides bringing benefits, the complex technologies used in the instruments also increase the risk of cyber attacks of various kinds. Concerned with this, INMETRO ‘s Board of Legal Metrology establishes technical requirements for software and hardware security, so that such measurement instruments can be verified.

The requirements requested in software testing are divided into 3 groups:

⦁ Documentary evaluation: It consists in analyzing the textual documentation provided by the applicant that proves compliance with the technical safety requirements;

⦁ Source code analysis: It seeks to evaluate the safety of the solution implementation described in the documentation;

⦁ Functional Testing: It consists of a test collective to verify compliance with software and hardware technical safety requirements when various inputs are applied to the instrument;

Based on this, MODERACON offers a customized consulting service for software evaluation requirements. Our goal is to make your product and documentation adequate to the new requirements defined by INMETRO.

Our technical team has great experience in this issue, having actively participated in making viable dozens of projects in the metrology segment. Let’s talk?
