What is the official definition of a 'sealant' according to this code?

A material which, when applied to a joint, cures to a solid, functional material that seals the joint by adhesion and cohesion while accommodating expected movement.

What is the difference between 'adhesion' and 'cohesion' for a sealant?

Adhesion is the sealant's ability to stick to the joint substrates (e.g., concrete, glass), while cohesion is the internal strength of the sealant material itself, resisting tearing.

The period of time during which a multi-component sealant remains suitable for application after the components have been mixed. (Term 2.4.15)

What does 'tooling' a sealant mean?

It is the act of pressing the sealant into the joint to ensure complete contact with the surfaces and to achieve a neat, finished appearance. (Term 4.1.3)

Practical Notes

Essential for correctly interpreting technical data sheets (TDS) from sealant manufacturers.

Use this standard to write clear and unambiguous specifications for sealant works in contracts and drawings.

While this is an old code, its fundamental definitions are still relevant and are referenced by other modern sealant testing and specification codes.
