Suppliers9 procedures
The supplier's procedure should cover:
a)
ensuring their equipment conforms to their published technical data;
NOTE
Where multiple versions of similar equipment are available, the supplier should ensure that each
version can be easily identified and conforms to the appropriate technical data. Limitations on use of mixing
versions should be identified in the data.
b)
the original design of the components, verification and production of technical information for
individual and assemblies of proprietary items;
c)
ensuring that manufactured and repaired items conform to the original design requirements for
the initial and all subsequent production through the application of robust quality control;
d)
material handling and transportation;
e)
maintenance and repair of items that are hired or offered for second-hand sale; and
f)
equipment substitutions when the original component is not available.
10.4
Verification of design information
10.5
The supplier should carry out sufficient calculations and testing to prove the capacity of all temporary
works components/equipment, including connections. Calculations and any necessary testing should
be carried out to recognized standards. Any testing should be representative of the actual conditions
of use and be sufficient in number to give statistically significant results.
Provision of information
The supplier should provide all information necessary for the design, assembly, use, dismantling and
maintenance of components offered for use as temporary works equipment. Performance data issued
by a supplier of equipment can reasonably be relied on without further justification.
The information should relate to the properties of the individual components, their use in expected
assemblies, and any specific requirements or constraints for use, inspection and maintenance. The
information provided to third parties should be sufficient to enable them to carry out their own
design(s) or independent checking of the supplier9s design.
10.6
Provision of design data
The supplier should either provide published technical data or justify the capacities by specific
calculations and certificates (see also 10.5).
NOTE 1 Attention is drawn to section 6 of the Health and Safety at Work, etc. Act 1974 [5] and the duty of suppliers
and importers of equipment to supply relevant and correct performance data.
The design data should include:
a)
the intended uses for the components and how they can be identified;
b)
appropriate dimensions, section and material properties and masses;
c)
structural properties for various conditions of use, such as different extensions and
eccentricities, together with details of any necessary bracing or lacing;
d)
a clear statement on whether capacities are in terms of characteristic strength or maximum safe
working loads;
e)
what factors of safety have been included or assumed;
NOTE 2 For characteristic strength this includes recommended partial material and load factors. For
maximum safe working load this is the global factor on the failure (see also 16.9.4).
