The scope of the inspector responsibilities who monitor and control the quality control
process are also defined
What two items if using API 936 are mandatory to be done?
The refractory applied by this guideline shall be sampled and tested to verify that
physical properties meet intended criteria
What is the acceptance / rejection criteria for qualifications testing as per API
936?
For both material and applicator qualification testing, the average physical properties for
each sample shall fully meet the criteria established for that material in API 936
What are the acceptance / rejection criteria for as-installed testing?
Based on criteria and procedure prior to work to start
What are the qualifications of inspection personnel?
1. The inspector shall have no commercial affiliations with the contractor or
manufacturer(s), unless otherwise agreed to by the owner
2. The inspector shall have a working knowledge of applicable standard and terms as
defined in attached appendixes of this document
3. The inspector shall have a working knowledge or requirements defined in this
document, owner specifications and job specific requirements outlined by the owner or
manufacturer.
What are the responsibilities of inspection personnel?
1. The inspector shall monitor qualification and production work conducted by the
manufacturer(s) and contractor to ensure compliance with job specifications and
agreed-to-quality standards
2. The inspector shall notify the owner and the contractor in a timely manner of any
work deficiencies or potential deficiencies based on his or her monitoring of material
qualification and the installation process
3. The inspector shall make no engineering decisions contrary or in addition to specified
requirements
4. Any conflict between specified standards and installed refractory quality shall be
submitted to the owner for resolution
5. In cases involving repair and maintenance of existing equipment, the owner may
request the inspector to provide recommendations concerning the need and extent of
repairs and procedures to be used to make those repairs
6. The inspector shall inspect the hammer test newly-installed lining before dry out and
after dryout (when possible), and report any anomalies to the owner
7. The inspector shall ensure the material and applicator qualification test results are
, fully documented and the contractor is provided with all applicable data for the materials
