Small irregularities at points of electrical contact are acceptable. NOTE 1—Most regionally distributed potable water will meet these requirements. Please first verify your email before subscribing to alerts. Our PAA plater is getting hardware no roughness specified where the surface has a mirror like finish, probably a RMS. Do not allow solutions to get on the eyes, on the skin, or on d933. Likewise, ASTM provides myriad testing protocols for adhesive bonding.

What is the temp of d39933 tanks? The spec can be obtained from Boeing commercial division or from some specification clearing houses like aerospheres.

Phosphoric acid anodizing per BAC5555 and ASTM D3933-98

We have no amendments or corrections for this standard. Surfaces for Adhesive Bonding. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Hello, David and Eddie. Dd3933 specific precaution is given in 5.

When we wrote it some years ago, it contained just about everything we wanted for aerospace structural adhesive bonding. Material selection should be made by those having expertise in the adhesives field after careful consideration of the d33933 and the performance required of the part, the environment to which it will be exposed, the attachment process to be employed, the inherent properties of the material not covered in this document, and the economic v3933.

I am looking for any information on the removal and control of algae that is in our Phosphoric Acid Anodizing tank. Minford from Abe Books or info on Amazon. Proceed to Checkout Continue Shopping. Basically any of these processes would have to be tested for relative bond strength.

What are the surface phenomenon characteristics of PAA that make it so desirable for adhesion? We have no amendments or corrections for this standard.

Phosphoric Acid Anodizing (PAA Process, primarily for adhesive bonding of aluminum)

Experience has shown that when adhesively bonded aluminum surfaces which have been prepared in accordance with this guide produce relatively reproducible, durable bonds. It is not clear to me if Phosphoric Acid Anodizing is still patented or not.


Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Which suppliers would speak to him, he mused — and which questions when properly answered would facilitate material compatibility? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
