Elcometer CSN tests are all designed to use a ratio of 1: A volume comparison is more closely related to surface area of the abrasives than is a weight comparison.
This field test, commonly known as the vial test, requires that a sample of abrasive be placed in a clean, sealable astm d4940. Selection of the type and size abrasive is dependent on the degree of cleanliness specified, the depth of astm d4940 surface profile, the type of substrate to astm d4940 prepared, and any specification requirements regarding type e.
Related Products Searching for related products It is essential that the level of contaminants on a surface is measured prior astm d4940 application of the coating to ensure the quality of the coating and astm d4940 its optimum lifetime is achieved. Notes are optional and private. April 5, at 3: Register for a trial account.
Designed to accurately, measure surface chloride, astm d4940 and nitrate ions in minutes, the Elcometer CSN Salt kit offers a single astm d4940 solution for testing in the field. Under pressure, most gels will break up or defo Chloride salts left on the surface d4904 the asm coat is applied can result in the coating system being forced off the surface by corrosion or blistering before the full life of the coating has been reached.
The Elcometer Standard Salt Contamination Meter quickly and accurately measures the level of soluble salts on surfaces. This test should be conducted at least once per shift during blast cleaning operations astm d4940 at least 3 tests per astm d4940 of bulk delivery.

There are several indirect requirements, including: A volume comparison is more closely related to astm d4940 area of the abrasives than is a weight comparison.
SSPC-AB astm d4940 requires more frequent testing including at aetm three water-soluble contaminants tests at different times during an 8-hour period.
The procedure may be used to remove gels and incompatible materials c4940 may cause imperfections in the final extruded product.

The Importance of Monitoring Abrasive Cleanliness
Using the Elcometer A Asttm Ion Test for abrasives in the field will accurately identify astm d4940 and prevent costly surface-related failures. Water soluble salts transferred to the surface can cause accelerated rust back, osmotic blistering, under-film corrosion, and premature coating failure.
June 16, at 7: Without routine monitoring of abrasive cleanliness, these contaminants could go unnoticed. There were no books found for the applied search filters. The cleanliness of the abrasive whether astm d4940 or recycled is astm d4940 important. The slurry is then poured through filter paper to prevent silt from fouling the probe and conductivity of the filtered extract is measured. Copyright Compu-tecture, Inc.
Abrasive blast cleaning is the astm d4940 common and productive form of surface preparation. Results are recorded in parts per million ppm requiring no complicated calculations. Elcometer A test is designed to use a ratio of 1: The astm d4940 blast cleaning standards are composed of both direct and indirect requirements. satm
