This is a complete set of the MRATs across all material areas.

This is a large file and may take some time to download over a slow connection.

We have made this available, but would expect schools to extract the MRATs that are specific to their needs, and only use this as a reference.

The bonding together of two pieces of metal, the joint being created by a layer of molten alloy, the flow of which is assisted by a flux. Brazing utilises a filler alloy having copper as the major constituent and is a higher-temperature process than silver soldering, where the filler alloy contains a high proportion of silver.

The creation of a joint between copper pipe fittings or between sheet lead using molten solder with a flux. Soft solder is an alloy of tin and lead with traces of other metals. The flux may be in cores in the solder or supplied as a liquid or jelly. 

The creation of a joint between the faces of sheet metal components or between wires and terminals using molten solder with a flux. 

Circular Saws – the cutting of large sheets of material to size. The forming of rebates or grooves in wood based materials.Jig saws – the cutting of curved or irregular shapes from wood-based materials.

The finishing of large sheets or workpieces too large to bring to fixed machines. Most portable power tools are electrically operated, increasingly with integral low-voltage battery packs but pneumatic tools are used if compressed air is available.

The creation of grooves, rebates and shaped edges of boards using a rotating cutter. Most portable power tools are electrically operated but pneumatic tools are used where compressed air is available. The use of tools with integral low-voltage battery packs is increasing.

The smoothing of sawn timber, or the machining of planed timber to a required size, especially when the work piece is too large for a fixed machine, or where a fixed machine is not available.

The construction of biscuit joints, often in manufactured board. A small circular cutter, similar to a small circular saw blade is used to create a curved recess that will accept the “biscuit” that forms the joining piece These tools may be powered by mains electricity, compressed air or low-voltage battery packs.

Cutting through brick and blockwork walls to form an opening and other cutting tasks such as cutting walls and concrete to form channels for services and cutting paving slabs and similar to size.Cutting through metal sections of various sizes and materials.
