It should be noted however, that pencil hardness is not the most reproducible test and interpreting the results is somewhat subjective.

These properties may be evaluated following the test methods listed in It would therefore be bene? Flammability Testing Equipment Toys Testing Equipment Impact resistance has also been found to be a good indication of whether a coating powder has been adequately cured.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Last previous edition D — Where more than one test method is listed for the same characteristic, no attempt is made to indicate superiority of one method over another. We have no amendments or corrections for this standard. Interpretation of the test results will depend on the specific d451 in question and will also often depend on the chemistry of the coating powder used.

The cured weight loss may be requested in order to properly determine the exhaust requirements of a bake oven or to comply with state or federal reporting guidelines. It is wstm responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Thank you for all.

The comparison of results are only valid for coating powders tested in the same laboratory at about the same time, not x3451 between different laboratories. Determine the susceptibility of a powder coating to? However, a quick calculation method, as listed below, has been proved in practice to be satisfactory when applied to coating asttm plants. Some coating powder chemistries can be inherently resistant to impact fusion even though their tack temperature might be relatively low.

Test for salt spray in accordance with Practice B Xenon arc lamp power. No other units of measurement are included in this standard. Some SCAB test methods will also include an accelerating weathering test see Section c3451 of this guide.

To obtain precise and reliable LEL results, it is best to employ the service of an independent laboratory, which has the special apparatus needed. Environmental Test Chamber 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.

Do not use abrasives to clean the bar. In either case, it is important that the viewing and measurement conditions under which color difference is to be evaluated are agreed upon between the purchaser and seller see Asphalt Testing Equipment These conditions, as well as the type of substrate, substrate preparation, etc.
