The abrasive shall meet all the requirements of paragraphs 4. Thank you for interesting in our services. SSPC-AB spc requires additional field and laboratory tests for cleanliness to help ensure the abrasive recycling abb is functioning properly and that the abrasive operating mix is still adequately sized. The blast pot shall be disconnected and weighed before and after each blast trial, and the following data recorded: Size px x x x x Ba it may not be required by the specification, it is good practice to first conduct a test panel to confirm the planned method of surface preparation will sspc ab 1 the specification.

New or Revised SSPC Standards Issued in 2017

Specifiers use it to ensure that non-metallic abrasive is properly sized, that its crystalline silica content is identified, and that it will not deposit contaminants on the substrate being cleaned. This standard provides laboratory performance testing benchmarks and acceptance criteria for moisture-cured aromatic polyurethane coatings containing micaceous iron oxide pigment reinforcement.

March 3, at It is important that the conductivity meter compensate for temperature and that the probe is verified for accuracy using a controlled solution with a known sspv value prior to use. The degree of embedment from abrasive blast cleaning operations can vary sdpc even within a generic category of abrasive. The frequency and lot size of inspection shall be established by mutual agreement between the supplier and the purchaser.

The conductivity of the abrasive shall not exceed microsiemen when tested in accordance with ASTM D see Note 7. Manufacturers may use the standard to evaluate the performance of their coatings. Thank you for your question Mr. The maximum moisture content shall be 0. We need your help to maintenance this website. Please fill this form, we will try to respond as soon as possible.


This includes personalizing content and advertising. This list shall include the title of the test, the appropriate standards used, any deviation from standard practice, and the numerical results of the testing. Three or more sacks of abrasive shall be randomly selected from each inspection lot. One sack of abrasive shall be randomly selected from each inspection lot and a sspd kg 4 lb composite sample prepared in accordance with ASTM C Therefore, it is important to select the proper sampling loca tion, and to use proper techniques to select the sample.

This cleaning technique will reveal an existing surface profile, but will not create one. Print this Article Send to Colleague. Qualification Testing and Conformance Testing 5. Your email address will not be published. Selection sspc ab 1 aab type and size sspc ab 1 is dependent on the degree of cleanliness specified, the depth of the surface profile, the type of substrate to be prepared, and any specification requirements regarding type e.

I do not think anyone zspc confidently quantify abrasive contamination transfer to a surface during abrasive blast cleaning, as there are too many variables to consider. Abrasive embedment is inevitable and is not normally detrimental, but if the abrasive is contaminated, so is the embedment.

There are many factors that impact quality and productivity during abrasive blast cleaning operations, but sspc ab 1 abrasive quality is critical for long-term performance of the applied coating system. The sacks shall be mixed and separated and a 50 kilogram kg lb composite sample prepared in accordance with ASTM C This standard contains composition and performance acceptance criteria for initial qualification of non-metallic abrasive media, as well as cleanliness requirements for recycled media.

Referenced Standards amendment of the referrefer 3. March 7, at 9: Each trial shall cover approximately 20 sq.

The crystalline silica content shall be determined by the use of infrared spectroscopy or by other analytical procedures, such as wet chemical or X-ray diffraction analyses. Abrasives designated as Class A or B must meet the requirements of paragraphs 4. Place in succession the grains thus differentiated between two glass microscope slides.


Kaunteya, the following is a response from sspf author, John Todd: Abrasives shall contain no more than 1.

SSPC SP 10 pdf | William Vargas Villa –

If dust settles on the surface or water remains cloudy, the overall cleanliness of the abrasive spsc sspc ab 1 questioned as this could cause impede production. The abrasive consumption rate shall be determined as the weight of abrasive used divided by the area cleaned, and reported in lbs of abrasive per square foot kg per m2.

Examine the material under low-power microscope 10X and if grains of different colors or character are present, select a few grains of each. The cleanliness of the abrasive whether new or recycled is equally important.

It contains discussions of the risks associated with overcoating, methods of assessing risk, and means by which risks may be managed and reduced.

This field test, commonly sspc ab 1 as the vial test, requires that a sample of abrasive be placed in a sspc ab 1, sealable container. The maximum permissible loss on ignition is 1.

If oil is visually evident, sspc ab 1 swpc fails the test. There are several indirect requirements, including: SSPC-TU 3 is a resource for facility owners and others charged with developing and implementing maintenance painting programs. All subsequent analyses performed on the selected sample are likely to be ba by particle size, so it is imperative that every reasonable effort be made to select the sample in a way that will assure proper representation.

The required conformance tests are particle size distribution Section 4.

The frequency and lot size for quality conformance testing shall be mutually agreed upon between the supplier and the purchaser.
