Contents of the rar-file:
1. BS 1139-1.2:1990 Metal scaffolding. Tubes. Specification for aluminium tube;
2. BS 1139-2.1:1991, EN 74:1988 Metal scaffolding. Couplers. Specification for steel couplers, loose spigots and base-plates for use in working scaffolds and falsework made of steel tubes;
This British Standard specifies the requirements for materials and design, and test procedures and methods, for couplers, loose spigots and base-plates used for connecting steel tubes of 48.3 mm outside diameter and of at least 3.2 mm nominal wall thickness at a minimum in the construction of working scaffolds and falsework required for the construction, maintenance, repair and demolition of buildings and structures.

When no alteration has been made to the design, material or surface treatment of a type of coupler which has been approved as a prototype according to this British Standard, the assessment of subsequent production is made by comparison with the requirements given in this standard.

Some significant points about this Section of BS 1139 to which attention is drawn are the following.

a) Other scaffold couplers and fittings commonly in use in the UK are dealt with in BS 1139-2.2.

b) For right-angle and friction type sleeve couplers there are now two load classes.

c) The minimum permissible base-plate area is now a little smaller.

d) Load bearing parallel couplers are now specified.

e) There is an increased minimum yield strength requirement on all coupler fasteners (typically bolts) together with a restricted torque tightening/wedge range.

f) The philosophy of testing has been changed to verify an individual coupler design and facilitate on-going quality assurance.

g) Additional information is required to be marked on all products.

h) There is limited information on hexagon sizes. The United Kingdom scaffolding industry generally requires hexagons to be between 20.3 mm and 20.8 mm across flats.

3. BS 1139-2.2:2009 Metal scaffolding. Couplers. Aluminium couplers and special couplers in steel. Requirements and test methods;

4. BS 1139-3:1994 Metal scaffolding. Specification for prefabricated mobile access and working towers;

5. BS 1139-4:1982 Metal scaffolding. Specification for prefabricated steel splitheads and trestles;

6. BS 1139-6:2005 Metal scaffolding. Specification for prefabricated tower scaffolds outside the scope of BS EN 1004, but utilizing components from such systemss;

BS 1139-2.2:2009 Metal scaffolding – Part 2: Couplers – Section 2.2: Aluminium couplers and special couplers in steel – Requirements and test methods

This section of BS 1139-2 specifies requirements and test methods for
aluminium alloy couplers and steel fittings for use in scaffolds and
falsework constructed with scaffold tubes conforming to BS EN 39,
types 3 and 4, or BS 1139-1.2.
It is applicable to:
• aluminium right-angle, swivel and sleeve couplers;
• steel putlog couplers, expanding joint pins and reveal pins;
• steel putlogs, putlog adapters and toe-board clips; and
• aluminium or steel castors.
NOTE Steel right-angle, swivel, sleeve and parallel couplers are covered
by BS EN 74-1.

EN 12811-3:2002 Temporary works equipment - Part 3: Load testing

This European Standard specifies rules for load testing, documentation and evaluation of
test results in the field of non mechanical temporary work items.
Note This standard is provided for use by all working groups of CEN/TC53 as a basis for standards which include
testing. While this standard provides general rules, it is anticipated that where special requirements are
necessary, they will be specified in the individual standard, for example the details of the test procedure.

EN 12811-2:2004 Temporary works equipment - Part 2: Information on materials

This European Standard provides guidance on where to find information on materials often used in temporary
works. It draws attention to a number of points that a designer should take into account.
The information given is limited to commonly used steel, aluminium alloys, cast iron, timber and timber based
materials.
Requirements are also given for welding, for limiting corrosion and other deterioration.
It is limited to the selection of types and grades of material from standards, which are either international or
European Standards.
