A batch inspection is a check by an impartial body of a specific, defined quantity of products (batch).
The purpose of batch inspections is to determine whether there is sufficient confidence that the characteristics of the products of that batch are in accordance with the established requirements.
Batch inspections are possible for products for which there is no BENOR or COPRO certificate, the producer does not have a certificate for the relevant product, or for which additional requirements have been imposed.
Party inspections always concern a well-defined quantity of the product to be inspected. The entire batch must be available at the time of inspection.
The inspection is one-off and in principle only the final product is assessed. Thus, a batch inspection cannot provide guarantees concerning raw materials or a production process.
Standard Specifications 250 for road construction, applicable in the Flemish Region, lists the products (Table 3-0-1) for which batch inspections must be carried out. In the Brussels and Walloon Region, the rules for possible batch inspections must be determined in the framework of the tender documents (additional articles related to the standard contract documents, special clauses, …).
The requirements with which the product must comply are laid down in an ‘inspection document’. This is based on:
- a standard;
- a model or standard specification (e.g.: Standard specification 250, CCT Qualiroutes, TB 2015);
- a special specification;
- a technical regulation (PTV);
- a written agreement.
If a batch meets the requirements, a ‘certificate of conformity’ is issued, indicating that there is a sufficient degree of confidence that the batch in question complies with the inspection document.
This certificate states:
- the product;
- the quantity;
- the applicable identification;
- the construction site.
If a batch does not meet the requirements, a ‘non-conformity report’ will be issued, indicating that the batch concerned has been inspected but is not in accordance with the inspection document. It clearly indicates which characteristics fall short.
A certificate and a non-conformity report are valid only for a single construction site.
The products presented are marked with a batch number. This is the first stamp.
The batch is sampled and tested.
If the results meet the requirements of the inspection document, the products are marked with the COPRO logo. This is the second stamp. The certificate is delivered to the party requesting the batch inspection, which in turn submits it to the client.
A batch inspection gives confidence that the product meets specific requirements, under the supervision of an impartial body.
Subject to approval and under the responsibility of the leading civil servant, batch-approved products may be used. In Flanders, batch-approved products may replace certified products.
How to recognise?
A batch-approved product can be recognised by the certificate of conformity and the identification of the product (marking with batch number and COPRO logo).
COPRO performs batch inspections for various construction products on behalf of the user or the producer.
All the provisions of batch inspections are described in the COPRO batch inspection regulations (PKRL), which you can download here.
COPRO also carries out batch inspections on precast concrete products commissioned by PROBETON. For more information we refer you to www.probeton.be.
