Practical Notes

This is not a design standard; it does not provide dimensions, spacing, or material specifications for joints.

Crucial for specification writers and architects to ensure the intended joint type and function are clearly communicated on drawings and in tender documents.

Using precise terms from this standard can prevent costly on-site errors and disputes regarding joint construction.
