ASTM D – 06() – Standard Guide for Testing Coating Powders and Powder Coatings

About Us About Us. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. I really would like to work with YUYANG, their professional service on the laboratory solution and reliable products help me win much market! Control and monitoring wavelength.

Guide G provides information on sources of asgm in weathering tests, and suggests procedures that can be used d3415 cope with this variability. To obtain precise and reliable LEL results, it is best to employ the service of an independent laboratory, which has the special apparatus needed.

No other units of measurement are included in this standard. They cover determination of v3451 pressure mottling and sticking, or blocking resistance of powder coatings applied to metal coil and blanks, or wood as they are stored prior to the?

It is applicable to both thermoplastic and thermoset coatings, unless indicated otherwise. However, it is suggested that unless otherwise agreed upon, panels for outdoor exposure should be prepared in accordance with Section 21 of this guide.

For powder coatings applied to coil strip or blanks, the standard elongation test used is the T-bend. Flammability Testing Equipment In the case of a thermoset coating powder, an accelerated storage sstm test can allow a powder user to predict the physical and chemical stability of a coating powder in order to determine its long term usability as a function of time and temperature. Where more than one test method is listed for the same characteristic, no attempt is made to indicate superiority of one method over another.

Selection of the methods to be followed must be governed by experience and the requirements in each individual case, together with agreement between the purchaser and the seller. We have received all the instruments, and will test them, for the moment we have very good feelings. Some coating powder chemistries can be inherently resistant to impact fusion even though their tack temperature might be relatively low. However, at unrealistically high irradiance levels, high amounts of near infrared energy can cause unrealistic temperature differences in differently colored materials.

Many properties of powder coating?

The results are most meaningful when a control powder, one whose? Xenon arc exposure produces temperature differences between dark and light color that is similar to those in outdoor exposure.

Requirements within therecycled water. Interpretation of the test results will depend on the specific application in question and will also often depend on the chemistry of the coating powder used.

Practice G describes procedures for conditioning and handling of specimens that are being tested in laboratory accelerated or outdoor exposures. These properties may be evaluated following the test methods listed in Toys Testing Equipment Thus, it is not possible to assign an acceleration factor to a speci? Where more than one test method is listed for the same characteristic, no attempt is made to indicate superiority of one method over another.

D33451 Storage Stability Place the pointer at this point. Information on current test procedures for pipe and reinforced steel bar coating powders and powder coatings can be obtained through their respective ASTM Subcommittees, A Last previous edition D — I’m Online Chat Now. This standard is also available to be included in Standards Subscriptions.

The degradation of a coating exposed outdoors is in? Melting Point Determination For a very smooth cured? Common terms associated with optical properties are de?

This test is most useful to the coating powder formulator.
