Frequently asked questions

Frequently asked questions about the technical bulletins

What is a Damasco Penna technical bulletin?

It is a two-page publication that deals with a single test or a design decision. It carries an objective data sheet, numbered sections, a technical note and the reference standards, written by engineers for engineers.

How often are new bulletins released?

There is no fixed calendar. Each edition goes out when the subject is closed, reviewed and with every source checked.

Do the bulletins cite standards and sources?

Yes. Every figure quoted requires a source, whether an NBR standard, a technical paper or our own data confirmed in the field. The procedure is validated against the corresponding Brazilian standard before being stated as a rule.

Where do I find the bulletin for the test I am interested in?

When the topic has a matching service, the bulletin is also offered on that service's page. To receive the upcoming editions, get in touch through our contact page.
