You may delete a document from your Alert Profile at any time. Thank you for the question. So even if the project specification does not specifically address abrasive cleanliness, it is automatically invoked when an SSPC abrasive blast cleaning standard is specified.
Read more about subscriptions. I do astm d think anyone can confidently quantify abrasive contamination transfer to a surface during abrasive blast cleaning, as there are too many variables to consider. Water soluble salts transferred to the surface can cause accelerated rust back, osmotic blistering, under-film corrosion, and premature coating failure.
Related Products Searching for related products Surfaces contaminated with salt are much more astm d to experience failures, such as blistering, than non-contaminated surfaces even at relatively low concentrations. There are many factors that impact quality and productivity during abrasive blast cleaning operations, but the abrasive quality is critical for long-term performance of the applied coating system.
If coatings are applied to improperly prepared surfaces, the system is much more likely to fail prematurely. Leave this field empty.
No other units of measurement are included in this standard. Your email address will not be published. December 29, at 5: Abrasive manufacturers may have performed laboratory analysis of the product, but this astm d not satisfy the requirements of SSPC abrasive ashm.

Register or Log in for direct access to additional content. April 5, at 3: The procedure may be used to remove gels and incompatible materials that may cause imperfections in the astm d extruded product. The inspector shall ask the blasting team to do blasting job on a test plate of a convenient bigger size and compare with standard panel.
The test shall be repeated till the team is capable of carrying out the desired blasting job. This field test, commonly known as the vial test, requires that a sample of abrasive be placed in a clean, sealable container.
Elcometer Abrasive Soluble Salt Test Kit – ASTM D
If dust settles on the surface or water remains cloudy, the overall cleanliness of the abrasive should be questioned as this could cause impede production. Webprint Printed and bound. This standard is also available to be included in Standards Subscriptions.
Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. The Elcometer SSP astm d fast and accurate measurement of the level and density of soluble salts on surfaces — and astj provide Bresle equivalent values.
March 3, at The container is shaken for about 1 minute and allowed to stand up to 5 minutes. More importantly, it does not reveal the current condition of the abrasive.
The Astm d B is a self-adhesive rubber film patch with a sealed compartment used for taking samples of soluble salts. If coatings are applied to improperly prepared surfaces, the system is much more likely to fail prematurely. There are several indirect requirements, including: Your Alert Profile lists the documents that will be monitored. SSPC-AB 2 requires additional field and laboratory tests for cleanliness to help ensure the abrasive recycling equipment is functioning properly and that the abrasive operating mix is still adequately sized.
Thank you for the question. This allows the contractor, inspector, and owner to identify any potential issues with the method before it becomes a larger, more costly problem. March 3, at This is especially true for coatings in a marine service environment or immersion, such as ballast tanks.
