Fire-Rated Casework It attaches to the assembly, not the drawing.

A tested assembly.

A rating is achieved by a specific construction, in a specific configuration, tested under a defined method. Change the construction and the evidence no longer applies to it.

A product and its manufacturer.

Rated doors, panels and assemblies are supplied by manufacturers who hold the test evidence for what they produce.

Not a drawing, and not a detailer.

A drawing can specify and locate a rated assembly. It cannot confer the rating, and no amount of detailing makes an untested construction rated.

Which items require a rating, and what rating.

Named in the specification, and frequently varying between locations in the same building.

How the rated item meets what surrounds it.

The junction between a rated assembly and the construction around it is usually where the requirement is either satisfied or lost.

Which components may be substituted, and which may not.

Substitution on a rated assembly is a different question from substitution elsewhere, because the evidence attaches to the tested configuration.

What evidence the project requires and when.

Certificates, test references and product data, with lead time that belongs in the programme.

The testing authority conducts the test

and issues the evidence.

The manufacturer holds the certification

for the assembly it produces, and supplies it as part of the product.

The fabricator carries the obligation

to build what the specification requires and to install it so the rating is not compromised.

BluEnt detailing does none of these.

We detail to what the specification imposes and report what it requires. We do not test, rate, certify or approve any assembly, we do not issue compliance certification, and we are not a certifying authority.

What detailing can do is make sure the rated item is identified, located, dimensioned and detailed at its junctions so the requirement is visible rather than assumed.

A rating priced as standard casework.

The requirement is in the specification, reads as a note, and the product cost and lead time are not in the number.

A substitution made on a rated item.

Legitimate elsewhere, and on a rated assembly it invalidates the evidence unless the alternative carries its own.

The junction ignored.

The item is correct and the condition around it is not, which is where the requirement is most often lost.

Evidence assumed to arrive with the drawing.

It arrives with the product, from the manufacturer, and it has to be requested.
