ASTM D5144-08 (R2021) pdf free download.Standard Guide for Use of Protective Coating Standards in Nuclear Power Plants.
1.1 This guide provides a common basis on which protective coatings for the surfaces of nuclear power generating facilities may be qualified and selected by reproducible evaluation tests. This guide also provides guidance for application and maintenance of protective coatings. Under the environmental operating and accident conditions of nuclear power generation facilities, encompassing pressurized water reactors (PWRs) and boiling water reactors (BWRsL coating performance may be affected by exposure to any one, all, or a combination of the following conditions: ionizing radiation; contamination by radioactive nuclides and subsequent decontamination processes; chemical and water sprays; hightemperature high-pressure steam; and abrasion or wear.
1.2 The content of this guide includes:
4.2 The testing referenced in this guide is particularly appropriate for safety-related coatings inside the reactor- containment. Other test methods may he used for assessing the suitability for service of safety-related coatings outside the reactor-containment. Criteria for qualification and performance monitoring of Coating Service Level III coatings shall be addressed in job specifications. Guidance for selecting and performance monitoring of Coating Service Level 111 coatings is provided Guides D7230 and D7167 respectively, and See- lions 4.4 and 4.5 of EPRI 1019157 (formerly TR-109937 and 1003102.).
4.3 Users of this guide must ensure that coatings work complies not only with this guide, but also with the licensee’s plant-specific quality assurance program and licensing commitments.
4.4 Safety- Related Coatings:
4.4.1 The qualiti cation of coatings for Coating Service Levels I and III are different even though they are both safety-related. This guide provides the minimum requirements for qualifying Coating Service Level I coatings and also provides guidance for additional qualification tests that may he used to evaluate Coating Service Level I coatings. This guide also provides guidance concerning selection of Coating Service Level III coatings.
4.4.2 Coaling Service Level 1 Coatings:
4.4.2.1 All Coating Service Level 1 coatings must be resistant to the effects of radiation and must be DBA qualified. The test specimens shall be prepared. irradiated and DBA tested and evaluated in accordance with the requirements of:
(a) Test Method D3911 or plant specific requirements as applicable,
(b) Test Method D4082, and
(c) Specification D5 139.
4.4.2.2 In addition to the requirements of 4.4.2.1, Coating Service Level 1 coatings may be evaluated for additional qualities or may require application controls when deemed applicable by the job specifications or licensing commitments. The following documents provide guidance for application, possible additional testing or for the further evaluation of Coating Service Level I coatings when applicable.ASTM D5144 pdf download.
