You can read detailed information about the preliminary visit in the Rules of Accreditation, ATS-PA01

How long does the accreditation process take?

The initial accreditation procedure lasts, in accordance with the Law on Accreditation (''Official Gazette of the RS'', No. 73/2010, 47/2021), for a maximum of eight months from the date of submission of the applicant for accreditation. Exceptionally, the eight-month period can be extended at the written request of the applicant, and for a maximum of four months from the date of expiry of the eight-month period. See, ATS-PA01

Extending the scope of accreditation 

When can CAB apply for an extension of the scope of accreditation?

An accredited conformity assessment body can apply for an extension of the scope of accreditation at any time during the validity of the accreditation, which includes the extension of the scope of accreditation in the process of renewing the accreditation, provided that in that case no separate application for extension of the scope of accreditation is submitted (an application is submitted for renewal of accreditation), i.e. in the requested scope of accreditation, conformity assessment tasks for which the CAB requests an extension are identified. Assessment for the purpose of extending the scope of accreditation can be realized through an independent procedure or together with regular assessment in the accreditation cycle. All phases in the procedure are implemented as in the case of the initial assessment, excluding the implementation of the preliminary visit. Extending the scope of accreditation does not affect the validity period of accreditation. See, ATS-PA01

Application of the Rule ATS-PA05

What to do in a situation where a location that is a local legal entity also has accreditation from the NAB of the country in which the location is located (LAB)?

Before signing the agreement with the client, it is necessary to clearly determine which legal entity shall be responsible for the contract and under whose name the process of accredited conformity assessment shall be carried out. The entire procedure shall then be carried out in accordance with the management system of the accredited body engaged to perform the conformity assessment activity. All reports and certificates that are issued shall state the accreditation within which the activities are performed (the legal entity of the location accredited by LAB or the legal entity of the parent organization accredited by, for example, ATS).

Who is responsible for reviewing the contract, if it is done at the local level?

This is decided by the CAB. If the responsibility is transferred to the local level, the registered legal entity (parent organization, headquarters) shall take appropriate policies, harmonize procedures, and surveillance activities. In accordance with the interpretation of ''responsibility for accredited activities'' (point 5.1.6 ATS-PA 05).

Can a local branch staff sign contracts on behalf of a registered legal entity?

Signing a contract is a key indicator of accountability. There are two basic cases:

  • a separate contract is signed with each client. In this case, the contracts shall be signed by the staff of the registered legal entity.
  • a standardized contract is signed with clients. In that case, a standardized contract, e.g. in the form of a form in which the conditions, prices, and content of the assessment are specified, shall be approved by the staff of the registered legal entity. Acceptance of work related to such a contract can be signed by local staff authorized to represent the registered legal entity.
