If you missed the ITU Tutorial that included a presentation by Erik Øhlenschlæger​, ILAC AIC Chair, the background information and recording is now available here

This tutorial provides guidance for all stakeholders on the Testing Laboratories recognition procedure established by ITU, its benefits and the logistical details required for submitting an application for ITU recognition of a testing laboratory competent to test according to ITU-T Recommendations, in collaboration with existing accreditation bodies.

The ITU-T Guideline on Testing Laboratory Recognition procedure defines recognition criteria for TLs from laboratories that are accredited by an Accreditation Body (AB) that is a signatory to the ILAC Mutual Recognition Arrangement (MRA) for testing where the scope of accreditation contains ITU-T Recommendation(s).

ILAC published the ILAC Assessment Procedure in the field of Telecommunications​. This document was created in the framework of cooperation established under the Memorandum of Understanding (MoU) between the International Telecommunication Union (ITU), IAF and ILAC.

ILAC members and colleagues, we are abandoning our traditional Secretariat update covering all things ILAC for this edition of ILAC News, as it is with mixed emotions that I confirm this is the last edition of ILAC News from the current Secretariat.

A significant chapter in the history of ILAC comes to an end on 31 December when the contract between NATA and ILAC for the provision of Secretariat services concludes. The ILAC Secretariat has been staffed via a Deed of Agreement (DoA) with NATA since 1996 when the formal cooperation to establish ILAC was signed and even prior to this period, NATA resourced the Secretariat from the inception of ILAC as a conference in 1977.

Many of you will recall the key staff that have managed the ILAC Secretariat under the NATA DoA, in particular, Ann Margaret Gilmour and Alan Squirrell, who each made a significant contribution in supporting and growing the organisation from its earliest foundation.

On behalf of the current staff, Sharon, Hannah, Joelle, Rose, Stephanie and myself, I would like to thank all our members, liaison partners and colleagues and the IAF Secretariat for their support in progressing the work, profile and role of ILAC to become the internationally recognised organisation it is today. It has been a pleasure and privilege to work with all of you, with so many wonderful learning experiences and friendships made along the way.

During my time as the ILAC Secretary (2007 – 2023) I have been very fortunate to have had an exceptional team of loyal, skilled and dedicated staff that made it possible for the Secretariat to deliver the range of services that have continued to grow and expand over this period.  That is especially the case with the current team members working with me during these final months and I want to acknowledge their support, dedication and professionalism, without which it would not have been possible to maintain the required level of service.  

We will be actively working to support a smooth and comprehensive transition process to the new Secretariat team for the remainder of 2023 and during the first quarter of 2024.  Details of the new Secretariat will be announced by ILAC and IAF when finalised. The new Secretariat will be supporting and guiding you from 1 January 2024, and also working to prepare the foundations for a single international organisation for accreditation! We look forward to seeing the continued growth, development and acceptance of accreditation in the international arena.

The staff of the ILAC Secretariat send our very best wishes to all for a safe and exciting future.   

Thank you!

The inspection division of Cofrac in now offering a new accreditation scheme for the control and verification of removable structures to ensure the safety of people.

What is a removable structure?
A removable structure is a temporary and dismountable structure for sporting, cultural, commercial, or tourist events and consists of a framework that can be repeatedly assembled and dismantled for temporary use.
Removable structures are divided in two groups:

• Frames designed to support people which are subdivided into three classes depending on the fall height;
• Frames for stage equipment that are not used to support people are classified into three categories according to the risk they represent for people in case of overturning or collapse and the highest point of the frame installation.

Context and challenges of this accreditation scheme
In France, until 2022, there were no rules for verifying the mechanical strength of demountable structures, or for assessing an organization’s ability to control and verify them. However, the industry had created a practical guide that the safety commissions also relied on.

With the Paris 2024 Olympics Games approaching and safety issues at meetings associated with major gatherings, it is necessary to fill the regulatory gap.

A working group has been set up by the French Ministry of the Interior and Overseas Territories to draw up a technical reference system setting out the design, installation and operating rules, as well as the inspection and verification methods for these structures. This work was based on the “Practical Guide

– Dismantable Equipment and Assemblies” drawn up in 2017 by SYNAPSE and the “Good Practice Guide
– Dismantable Equipment and Assemblies” of the Paris Police Prefecture.

Cofrac was also involved in this work due to the Ministry’s decision to rely on accredited organizations to carry out these inspections.

What are these checks and inspections?
Controls and checks are divided into two phases:

• Design control – This check related to the stability and strength of the provisional designed structure (mechanical resistance, climatic constraints, human passage, etc.) is carried out before the first installation of the demountable assembly.
• Verification of assembly and inspection in operation – The aim of the verification of the set-up is to confirm that the assembly conditions comply with the technical prerequisites defined in the manufacturer’s manual or the technical file and to verify the strength and stability of the dismountable assembly.

On October 1, 2022, Cofrac launched the accreditation scheme according to the NF EN ISO/IEC 17020 standard for two areas of inspection: the design control and the verification of assembly and operational inspection. The assessment plan relies on the decree published on August 5, 2022, setting out the safety rules, technical provisions, inspection control obligations and conditions applying to these temporary and dismountable structures.

This scheme has two specificities:

• The difference in the type of independence of the inspection body. As part of the design inspection, the organization must meet type A, so-called “third party” requirements. Unlike organizations for assembly verification which can be either type A or C with a requirement that they do not check the removable structure they have assembled.
• A dual approach to the design control activity: approval or accreditation. The regulatory framework authorizes bodies approved as technical building inspectors to carry out design inspections without accreditation. This approval covers the strength of the structures, and technical inspectors were approved to give opinions on temporary structures by the safety commissions.

Accreditation is mandatory for organizations that are not approved technical inspectors. It therefore constitutes a real opportunity for these organizations to be able to provide this type of service, in view of their broader markets and skills.

Accreditation already existed for similar activities such as scaffolding, mechanical shelving and structural strength testing. To meet the demand for accreditation, Cofrac extended the qualifications of some of these technical assessors to these new schemes and has also qualified new assessors.

To date, 4 organizations are accredited for these new schemes, and others are in the process of becoming accredited.

Accreditation will be mandatory from 1 January 2024 for all inspection bodies wishing to operate in this technical field.

Municipal pipelines such as water supply and drainage, electricity, gas and communication are buried under urban roads which are affected by vehicle load, vibration, groundwater level and other factors. Disasters such as pavement collapse and cracking, are easily caused which result in inconvenience to urban production and life and may even cause personal injury. This is particularly the case in recent years, with the further expansion of the urban scale and the increasing density of underground pipe network in some cities. Geological disasters of urban roads are occurring frequently, which has attracted the increased attention of the municipal departments and the general public.

Similarly, the application of robot technology in the inspection of internal defects of urban sewer and non-excavation pipeline repair technology has attracted wide attention because of the advantages of high repair efficiency and low repair cost.

After a period of service, the materials used in urban roads and urban sewers gradually age and their functions decline potentially resulting in geological disasters and potential safety hazards. In order to find the potential safety hazards and take measures to eliminate them, it is necessary to regularly evaluate the risk of urban road underground failures and the internal defects of urban sewer. Since accreditation is an affirmation of the management and technical competence of the inspection body, there is an increasing demand for accreditation in the competence of risk evaluation in underground failures related to urban roads and the competence in internal defect evaluation of urban sewers.

CNAS has actively responded to the accreditation needs in the above fields organizing experts to study and discuss the characteristics and technical requirements of inspection and testing activities in these two fields, and promote accreditation of the inspection bodies. Following analysis, the inspection items for urban roads is the detection and evaluation of attributable characteristics of underground failures such as cavities underneath the pavement, voids, loosely infilled voids, water-rich voids in the area using detection methods such as ground penetrating radar method for urban roads according to relevant technical standards, and to carry out a risk evaluation. The inspection items for urban sewers are sewer defects and condition evaluation, including the detection of structural and functional defects of urban sewers using closed circuit television inspection and quick view pipe inspection methods using the relevant technical standards Then to evaluate and judge the structural and functional conditions of the sewer and calculate the rehabilitation index and maintenance index. These two types of activities include the typical characteristics of inspection activities. Therefore, inspection accreditation in accordance with ISO/IEC 17020 is applicable.

CNAS is accrediting inspection bodies in these two technical fields. Competence in the detection and evaluation of underground failures in urban roads and sewer defect and condition evaluation of urban sewers is accredited according to the inspection body accreditation standard ISO/IEC 17020. As of August 2023, in the above fields, a total of 31 inspection bodies have been accredited by CNAS, with more inspection bodies currently in the process of seeking accreditation for these activities.
