ANSI ASTM F941-1999 Standard Practice for Inspection of Marine Surface Preparation and Coating Application.pdf

1、Designation: F941 99 (Reapproved 2013) An American National StandardStandard Practice forInspection of Marine Surface Preparation and CoatingApplication1This standard is issued under the fixed designation F941; the number immediately following the designation indicates the year of originaladoption o

2、r, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1

3、.1 This practice is intended to serve as a guide fordetermining specific inspection requirements for marine sur-face preparation and coating application during newconstruction, major retrofit, or routine maintenance contracts.1.2 It is intended that this practice be used to coordinateinspection acti

4、vities between ship owner, ship builder, coatingsmanufacturer and coatings applicator, and that specific require-ments be developed before the commencement of surfacepreparation or coating application, or both.1.3 This practice does not provide a means of recordingrequired data (for example, film th

5、icknesses, temperatures,relative humidity, and so forth), but instead establishes a formatfor deciding what data must be recorded, when during thepreparation/coating process, and by whom.1.4 This practice does not establish accept/reject criteria forsurface preparation or coating inspection, nor doe

6、s it addressmethods of repairing deficiencies found. It does, however,provide a means of determining them.1.5 This standard may involve hazardous materials,operations, and equipment. This standard does not purport toaddress all of the safety concerns, if any, associated with itsuse. It is the respon

7、sibility of the user of this standard toestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.

Significance and Use3.1 This practice may be invoked by any of the partiesmentioned in 1.2 and may be included as part of a specificationor used to clarify or reinforce an existing specif

23、ication that doesnot adequately address inspection. When invoked by the shipowner on the shipbuilder, the shipbuilder is responsible for thecoordination effort.3.2 As surface preparation and coating requirements gener-ally differ from ship area to ship area, this practice shall beapplied separately

24、to those areas of similar requirements.3.3 The contents of this practice shall be addressed (for eachapplicable ship area) at a prestartup meeting attended by theparties mentioned in 1.2.4.
