The frequency and lot size for quality conformance testing shall be mutually agreed upon between the ssppc and the purchaser. SSPC-TU 3 is a resource for facility owners and others charged with developing and implementing maintenance painting programs.
This cleaning technique will reveal an existing surface profile, but will not create one.
Conformance tests shall be conducted on each lot as required by the pur chaser. However, upon mutual agreement between supplier and purchaser, ag performance test procedure can be established. Each plate shall contain a minimum of 20 squares.
The substrate conductivity values after the surface prepn must be ensured under specified limit for specified checking frequency anyway! We are a non-profit group that run this website to share documents. In case ssspc dispute, the arbitration or settlement procedure, if any, established in the procurement documents shall be followed. Thank you for interesting in our services.
December 23, at 7: Back to Coatings Connect. A lb pot shall be charges with lbs kg of abrasive and the test sspf blasted to SSPC-SP 10 near-white condition. This list shall include wb title of the test, the appropriate standards used, any deviation from standard practice, and the numerical results of the testing.
Selection sspc ab 1 the 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.

SSPC-AB1 – 2017
This standard provides laboratory performance testing benchmarks and acceptance criteria for moisture-cured aromatic polyurethane coatings containing micaceous iron oxide pigment reinforcement. We need your help to maintenance this website. The following guidelines should be kept in mind when deciding on a sampling method: There are several indirect requirements, including: We sspc ab 1 had a big problem. Abrasives designated as Class A or B must meet the requirements of paragraphs 4.
The sacks shall be mixed and separated and a 50 kilogram kg lb composite sample prepared in accordance with ASTM C December 27, sspc ab 1 8: June 16, at 7: I do not think anyone can confidently quantify abrasive contamination transfer to a surface during abrasive blast cleaning, as there are too many variables to consider. All abrasives must be classed based on crystalline silica content see Note 7.
Transfer approximately 1 gram of the dried sample to a tared xb with cover and weigh to the nearest milligram. Your email address will not be published. This standard contains composition and performance acceptance criteria for initial qualification of non-metallic abrasive media, as well sspf cleanliness requirements for recycled media.
Three or more sacks of abrasive shall be xb selected from each inspection lot. The required conformance tests are particle size distribution Section 4.
Please help us to share our service with your friends. The percent of weight change shall be computed as follows: Therefore, it is important to select the proper sampling loca tion, and to use proper techniques to select the sample.

Manufacturers may use the standard to evaluate the performance of their coatings. 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 maximum permissible loss on ignition is 1.
The Guide is intended to assist specifiers and contractors who need to compare field test procedures and the information each procedure provides, along with other considerations, in order to select the most appropriate test procedure or procedures for use on a given project. The degree of embedment from abrasive blast cleaning operations can vary widely even within a generic category of abrasive.
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. Abrasive embedment is inevitable and is not normally detrimental, but if the abrasive is contaminated, so is the embedment.
The hardness shall be a minimum of 6 on the Mohs scale when tested as follows: Referenced Standards amendment of the referrefer 3. The surface cleaning rate shall be determined as the area cleaned divided by the time required to sspcc and reported in square feet espc meters cleaned per hour. The conductivity of the abrasive shall not exceed microsiemen when tested in accordance with ASTM D see Note 7.
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 abrasive shall meet all the requirements of paragraphs 4. The frequency and lot size of inspection shall be established by mutual agreement between the supplier and the purchaser. The cleanliness of the abrasive whether new or recycled is equally important.
Examine the glass surface, and if scratched, the material shall be considered as having a minimum hardness of 6 on the Mohs scale.
