A aztm in parentheses indicates the year of last reapproval. Standard guides for automotive and aerospace adhesives provide the proper guides for the classification, specification, preparation, and use of several adhesives on aluminum and metal surfaces. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Further, how could he verify supplier data found on a typical technical data sheet TDS in a manner that would be universally accepted as adhering no pun intended to good scientific and documentation principles without necessarily running every adhesives test known to the automotive world?

I work for a company that specializes in composite structures. This standard asttm useful in determining suitability c3933 an adhesive in applications where the odor level associated with end use is critical, such as vehicle interiors. He had to define many material characteristics and ultimately prove that the product would be functional, durable and corrosion-resistant in the aggressive transportation environment, which was no easy feat.

For alloys with a lot of Chrome, the aztm will become a greenish color. After priming, parts can be stored before bonding. You can download and open this file to your own computer but DRM prevents opening this file on another computer, d3933 a networked server. We currently have a small PAA outfit and would like to get it Nadcap approved. Anodize at ASF for minutes. Recently one of my long-time colleagues with an electrical engineering background retired.

Is this the fungus that I have read about or something else?

Phosphoric acid anodizing per BAC5555 and ASTM D3933-98

James’ recommendation was fromand even then the “Light Metals Finishing Process Manual” was quite hard to find. This seemingly daunting task did not faze him, however, as he had ample time to devote to it. Precision shall be reported in terms of the standard deviation of the data and the standard error of the mean.

Minford from Abe Books or info on Amazon. The next best process to PAA would be any method of etching the aluminum surface to roughen the profile. If the document is revised or amended, you will be notified by email. A specific precaution is given in 5.

I don’t know if the patents have run out on BAC or not — you’d have to do a patent search. If the document is revised or amended, you will be notified by email. From beautiful Pine Beach New Jersey: As the voice of the U.

Also, are there any alternative platings that can produce the same results? I don’t think this is possible, but I thought I should at least try to post the question. Do you know where I can get the info? Many factors, however, apply to shear modulus, aztm strength, and tensile modulus measured by small laboratory specimens in general.

At that time, Phosphoric Anodizing was best for most structural adhesive d333. Please first verify your email before subscribing to alerts. The preparation of the metallic substrates to obtain surfaces with appropriate characteristics is a critical step.

NOTE 1—Most regionally distributed potable water will meet these requirements. There are better, but cost a lot more.

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

The discoloration could be related to some of the alloying materials dissolved in solution. Can anyone tell me what equipment is needed to phosphoric anodize aluminum?

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. If you want a quick and dirty demonstration, make standard peel test specimens from candidate surface preps. Our PAA plater is getting hardware no roughness specified where the surface has a mirror like finish, probably a RMS.

I wouldn’t be too worried about it until the concentration climbs above what is allowed. Already Subscribed to this document. Material asfm should be made by those having expertise in the adhesives field after careful consideration of the design 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 factors.

Phosphoric acid anodizing is done with stainless steel cathodes. Quality Assurance Provisions 8. The methods may be revised or supplemented, as necessary, to include methods based on proven performance. We have no amendments or corrections for this standard.

Please first verify your email before subscribing to alerts. This standard is aastm to revision at any time by the responsible technical committee and must be reviewed every? These standards reflect many routine and practical applications.
