Colour change
In a commodity examination, this sign is described as the object's actual condition. The cause is established only when the source data is sufficient and within the limits of specialist knowledge.
What is recorded
The appearance, location and extent of the sign, packaging condition, labelling, batch information and available accompanying documents are described. For “colour change”, direct observation must be distinguished from an assumption about the cause.
Which materials help
- photographs of the goods and packaging in their original condition;
- dates of manufacture, acceptance, discovery of the change and inspection;
- information on storage temperature and humidity;
- transport and warehouse documents;
- records, claims and data on the condition of other units in the batch.
What can and cannot be inferred automatically
Darkening, fading, spotting and other changes in product appearance. However, a single external sign does not automatically establish the precise microbiological, chemical or other nature of the change. A relevant specialist examination is commissioned where necessary.
What to read next
Send materials for a preliminary assessment
Describe the situation and attach the available documents and photographs. After reviewing them, the work format, required materials, cost and time frame can be determined.
- we will check whether the task falls within commodity examination competence;
- we will determine whether documents and an inspection are sufficient;
- if specialist tests are needed, we will identify the laboratory component;
- we will indicate a possible format for the result.
