Expert laboratory of product examination

Expert Laboratory

The expert laboratory was created by expert Andrey Viktorovich for organizing and technically supporting commodity research in the preparation of specialist opinions, expert conclusions, reviews, and informational letters for the court.

The laboratory is intended for systematic accounting, storage, verification of technical condition, calibration, and maintenance of equipment used in conducting expert examinations. Its establishment allows for ensuring a unified procedure for working with research objects, measuring instruments, regulatory and technical documentation, photographic materials, and research results.

The laboratory's work is organized taking into account the approaches of GOST ISO/IEC 17025-2019 in terms of ensuring competence, objectivity, traceability of results, equipment management, documentation of research, and internal quality control.

Purpose of the laboratory

The laboratory was created so that each study is conducted under conditions that ensure the completeness, verifiability, and reproducibility of expert conclusions.

• organization of expert studies;
• accounting and identification of equipment;
• storage of measuring instruments, devices, and auxiliary equipment;
• control of calibration periods of measuring instruments;
• control of the technical condition of equipment;
• storage of passports, calibration certificates, instructions, and operational documentation;
• keeping the internal equipment registry;
• accounting for applied methods, GOST, technical regulations, technical specifications, and other normative and technical documentation;
• photographic recording of research objects, packaging, labeling, completeness, defects, and damages;
• storage of research working materials;
• ensuring traceability of obtained results;
• archiving conclusions, photographic materials, measurements, and research materials.

Equipment and measuring instruments

When conducting research, equipment is used that corresponds to the nature of the object and the questions posed.

Measuring instruments are used taking into account their purpose, technical characteristics, and current calibration documents. If necessary, information about the measuring instruments used, their characteristics, serial numbers, and calibration dates is reflected in the conclusion.

This procedure makes it possible to confirm which equipment was used for the study, under what conditions it was carried out, and on the basis of what data the conclusions were formulated.

Procedure for working with objects

Objects submitted for study are inspected, identified, and recorded.

If necessary, photo documentation is carried out of:

• the appearance of the object;
• packaging;
• labeling;
• completeness;
• signs of use;
• damages;
• defects;
• other features relevant to the study.

Research materials are stored in a manner that ensures their preservation, prevents mixing of objects, and allows for subsequent verification of the conducted study.

Methods of expert studies

Depending on the questions posed and the nature of the object, the following may be applied:

• visual method;
• organoleptic method;
• measurement method;
• comparative analysis;
• documentary analysis;
• analysis of labeling and completeness;
• analysis of consumer properties of the product;
• analysis of product compliance with regulatory, technical, and operational documentation;
• analysis of the causes of defects, damage, or loss of consumer properties;
• calculation of the cost of restorative repair, reduction in value, or amount of damage.

If a special laboratory test, chemical, materials science, physico-chemical, or other narrowly specialized study is required to answer the question posed, the results of specialized laboratories may be used, or specialists in the relevant field of knowledge may be involved.

Regulatory and technical framework

Applicable regulatory and technical documents are used in the research, including:

• technical regulations;
• GOST;
• technical specifications;
• manufacturer's operational documentation;
• instructions for use and storage of the product;
• information on labeling, composition, completeness, and characteristics of the product;
• documents on acquisition, repair, maintenance, transportation, or storage of the object;
• case materials, if the research is conducted within the framework of a legal dispute.

The applicable regulatory framework is determined individually, based on the object of research and the questions posed.

Documentation of results

Research results are documented in written form.

At the end of the work, the following may be prepared:

• specialist's report;
• expert's report;
• specialist consultation;
• information letter for the court;
• explanations regarding the issues of appointing a forensic examination;
• review of the expert's or specialist's report.

The conclusion reflects the presented materials, the questions posed, information about the object, the course of the research, the methods used, the regulatory framework, and the reasoned conclusions.

The importance of the laboratory for expert work

The presence of an expert laboratory makes it possible to ensure an organized and verifiable process of conducting research.

This is especially important when preparing documents for court, because the expert opinion must be not only reasoned but also verifiable: the court, the parties, and other participants in the process must understand which materials were studied, which methods were applied, which characteristics were identified, and on what basis the expert reached their conclusions.

The laboratory provides the technical and organizational foundation for preparing objective, comprehensive, and well-founded conclusions on issues of product examination.
