Volume 1: Verifying the Quality of Surface Preparation is the first eBook in the Three Volume eBook series Inspection Instruments for the Pipeline Coatings Industry
This self-study course is in eBook format. After reading this eBook, participants should be able to successfully:
- Recognize that abrasive cleanliness is an indirect requirement of the SSPC surface cleanliness standards for abrasive blast cleaning.
- Recognize that abrasive cleanliness testing applies to both new and in-process recycled abrasive.
- Describe the procedure for determining whether the abrasive is contaminated with oil.
- Describe the procedure for determining whether the abrasive contains water soluble contaminants.
- Identify the maximum allowable level of water soluble contaminants, according to the SSPC Abrasive Standards.
- Describe the procedure for verifying the accuracy of the conductivity meter used to determine the level of water soluble contaminants in abrasives.
- Define surface profile.
- Explain the proper use of a depth micrometer.
- Describe the minimum number of readings required by ASTM D4417 to characterize the surface profile in an area when using a depth micrometer.
- Identify the prescribed method of measuring the surface profile generated by impact-type power tools.
- Explain the proper use of a replica tape.
- Describe the minimum number of readings required by ASTM D4417 to characterize the surface profile in an area when using replica tape.
- Identify the size of an “area” according to SSPC-PA 17
- Identify the minimum no. of areas required to characterize the surface profile depth, per work shift.
- Describe the procedure for properly characterizing the surface profile depth using replica tape when readings fall between 1.5 and 2.5 mils.
- Explain the potential effect of peak count on coating properties.
- Explain the purpose of the SSPC Visual Guides.
- Explain the use of the SSPC VIS 1 Guide.
- Explain the use of the SSPC VIS 3 Guide.
- Describe when the ISO 8501-01 Pictorial Guide would be used in lieu of the SSPC Visual Guides.
- Explain the use of the ISO 8501-1 Pictorial Guide.
- List the methods commonly used to remove surface dust.
- Describe the importance of using clean, dry compressed air for surface dust removal.
- Describe the ISO procedure for establishing a dust quantity rating.
- Explain the consequences of coating over soluble salt contamination.
- Describe the differences between ion-specific and non-ion specific testing
- Calculate surface concentrations of soluble salt contamination levels
- Recognize that the acceptable level of surface soluble salt contamination must be specified in the contract documents, and there are no industry-wide acceptance criteria.
