12、is an integral part of the lining application process. The purpose of inspection is to verify compliance to the lining application specifications and work procedures, not to question the integrity of the lining applicator. Many lining applicators perform their own inspection or hire an independent i

13、nspection agency. The NACE International Coating Inspector Training and Certification Program provides exposure to knowledge and skills pertaining to inspection of lining application. The intent of this NACE standard is to provide appropriate inspection requirements to verify compliance to a lining

14、application specification. It is not intended to address the selection of the lining material(s) or to specify surface preparation and lining application requirements. This standard is intended for use by facility owners and their representatives, lining applicators, lining material suppliers, and i

15、nspectors involved with the inspection of lining application in steel and concrete equipment such as tanks, vessels, sumps, and basins. For further information on linings for concrete, refer to NACE No. 6/SSPC(1)-SP 131 and NACE Publication 02203/ICRI(2) Technical Guideline 03741/SSPC-TR 5.2 For fur

16、ther information about selecting and specifying surface preparation methods for concrete before application of linings, refer to ICRI Technical Guideline 03732.3 For further information on the design, installation, and inspection of linings, refer to NACE No. 10/SSPC-PA 64 and NACE No. 11/SSPC-PA 8.

22、o verify compliance to a specification for application of a lining in steel or concrete equipment such as tanks, vessels, sumps, and basins. 1.1.1 This standard is applicable to the application of a new or replacement lining, but is not applicable to the routine inspection of an existing lining. 1.1

23、.2 This standard does not address the selection of the lining material(s) or specify surface preparation and lining application requirements. 1.1.3 This standard does not apply to inspection of exterior coatings on steel or concrete such as atmospheric coatings or external coatings on pipelines or o

24、ther buried or submerged structures. 1.2 Successful lining application is usually the result of a well-prepared lining application specification, properly selected high-quality lining materials, a competent, experienced, knowledgeable lining applicator, and an inspector knowledgeable, and preferably

25、 certified, in lining inspection procedures. Adherence to a well-prepared lining application specification that clearly details industry-accepted requirements and procedures for quality lining application should result in a satisfactory application. The inspector relies on a well-prepared lining app

26、lication specification, which should include methods, specification standards, and acceptance criteria. 1.3 Specifications should be written with the purpose of designating materials and methods that result in high-quality linings appropriate for the user. Attention must be given to relevant details

27、 in a lining application specification. The specification should refer to industry standards whenever possible to minimize confusion or disputes over methodology and to reflect the latest technology that satisfies engineering and design principles for a particular application and environment. The sp

28、ecifications should include the acceptance criteria for the owner/user. 1.4 Inspectors shall have previously performed the functions outlined in this standard and be proficient in the use of inspection equipment. When required, inspectors shall provide necessary documentation and evidence demonstrat

29、ing suitable qualifications. 1.5 The inspector shall maintain a detailed report that outlines observations and measurements of surface preparation, ambient conditions, mixing techniques, application procedures, curing, final inspection, and other information requested at the prejob conference. 1.6 W

30、hen agreed to by the owner, an inspector shall have the authority to suspend lining application work if the work being performed is not in accordance with the lining application specification. Inspector responsibility and authority shall be agreed on by the owner and the contractor. _ Section 2: Pre
