There is no authority or organisation that licences or approves independent scaffold systems in the UK and it is therefore appropriate that the NASC provides a Code of Practice.
This document has been drafted in response to concerns at the increasing trend towards the manufacturing and importation of products that are visually similar to an original version but may not have been designed and manufactured to the same specification.
It is felt to be an important principle that, where an alternative version of an 'original' system is to be supplied in the UK, it meets certain minimum standards as determined by the NASC and that users of a system are able to make an informed choice between visually similar products.
It is envisaged that this generic document will be adhered to by manufacturers and suppliers of system scaffold in the UK and that in addition each system will be accompanied by a technical data sheet.
A. GENERIC SYSTEM STANDARD
The minimum standards that the NASC will endorse for a System
Scaffold are as follows:
1. DESIGN, MANUFACTURE AND TESTING
The product being supplied will have been designed and tested to the appropriate Standards.
Appropriate Standards include the following:
- Manufactured in accordance with BSEN 12810-1:2003 Part 1 - Product Specifications
- Designed and tested in accordance with BSEN 12810-1:2003. Part 2 - Methods of Structural design
- BSEN 12811-1:2003 - Scaffold performance requirements and General Design
- BSEN 1993-1 (Eurocode 3 Design of steel structures)
- Weld Testing Approval - Undertaken by an accredited testing house.
2. INDEPENDENT TESTING
The testing requirements are as follows:
- Component testing must be undertaken by an accredited independent third party testing house (eg Sandberg LLP) and satisfactory results achieved and documented.
- Key test requirements will include node point fixity & stiffness.
It is the responsibility of the UK supplier to ensure that genuine test certificates are in place for their product and that documentation is available for inspection in the UK.
3. QUALITY OF MANUFACTURE
The manufacturer must be able to demonstrate that they are subject to a formal audit procedure to confirm their viability as a reliable manufacturing centre.
The minimum requirements are that:
- The manufacturer has an auditable quality procedure in place. (eg ISO 9001)
- A Vendor Questionnaire is completed. This consists of a range of questions to ensure that the manufacturer meets the appropriate standard of any reputable supplier.
- Goods inwards quality inspections are made in the UK. This will consist of a robust goods inwards component checking procedure including the filing of controlled inspection sheets.
- Each component has reliable traceability to be able to test the quality of a specific component at any time it is essential that adequate data is recorded on the components. This data will include codes that enable key data to be traced, such as :
- Identity of Manufacturer
- Date of Manufacture
- Batch Number
4. PRODUCT LIABILITY
The UK supplier will be able to demonstrate that they have Product Liability insurance in place to a minimum value of £2m.
5. SYSTEM USER GUIDES
UK Systems must be accompanied by a system specific User Guide.
A User Guide written for a specific manufacturers system will reflect the capabilities and safe use of that product. It will not therefore be appropriate to rely upon a guide that was written for a different system.
Guide content must include:
- Safe methods of use
- Component drawings/descriptions
- Relevant product design information.
Where a particular system scaffold has features that prevent normal Safe Rescue methods from operating then the User Guide must provide details of a practical alternative method.
B. SYSTEM SPECIFIC STANDARD
The UK manufacture/supplier of a scaffold system will provide technical data relating to their own scaffold system. This data will include the following:
1 SUPPLIER DETAILS
Name of Supplier
Name of System
2 DESIGN & TESTING
Testing to BS EN 12810-2:2003 Table 1
BS EN 12810 Compliant
BS EN 12811 Compliant
BS EN 1993-1 Compliant
3 CLASSIFICATION/SYSTEM DETAILS
BS EN 12810:2003 sections 4 & 5
Standard - DIAMETER
Standard - WALL THICKNESS
Standard - STEEL GRADE
Standard - MAXIMUM LEG LOAD
System specific user guide available
4 QUALITY MANAGEMENT SYSTEM

Inspection & Testing Details (for e.g. BS EN 10204:1991)
Auditable quality procedures in place
Vendor questionnaire completed
UK goods inward inspections in place
Product traceability in place
5 PRODUCT LIABILITY
Limit of indemnity
It is the responsibility of each UK manufacturer/supplier to ensure that they can substantiate the specification and capabilities of their scaffold system if required.
