Paragraph 165 DEFINITIONS OF TERMS IN THIS ANNEX

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

“Superplastic forming” (1 2) means a deformation process using heat for metals that are normally characterised by low values of elongation (less than 20%) at the breaking point as determined at room temperature by conventional tensile strength testing, in order to achieve elongations during processing which are at least 2 times those values.
