purpose of this Guideline is to provide guidance for implementation of Performance Standard for Protective Coatings for dedicated seawater ballast tanks in all types of ships and double side skin spaces of bulk carriers hereinafter referred to as PSPC referred in the amendments to regulations II 1 3 2 and XII 6 of the International Convention for the Safety of Life at Sea SOLAS 1974 as amended adopted by resolution MSC 216 82 本指南旨在為進(jìn)行MSC 216 82 會議通過的SOLAS第 II 1 3 2和 XII 6 條修正案中所引入的 PSPC所要求的執(zhí)行提供指導(dǎo) The terms used in this Guideline have the same meaning as those defined in PSPC 本指南中所引用的術(shù)語與 PSPC 中的定義相同 These guidelines are developed based on the current available and approved types of paints and it is recognised that new types of paint maybe developed in the future for which all these requirements may not be appropriate It is recognised in these guidelines but that any deviation from these requirements will be specific to the paint being approved and form part of the testing and approved process to confirm their compliance with the requirements of MSC 215 82 as amended 本指南是基于目前已被認(rèn)可的涂料系統(tǒng)所提出的 這些要求對于將來開發(fā)出的新型涂料系統(tǒng)可能并不適用 任何 不是目前已被認(rèn)可的涂料系統(tǒng)的其它涂料系統(tǒng) 需經(jīng)檢測試驗(yàn)認(rèn)可 以證明該涂料系統(tǒng)符合 MSC 215 82 提出 的要求 2 2DefinitionsDefinitions For the purpose of this Standard the following definitions apply

that the required minimum level and quality of protective coatings by PSPC is adequately applied 涂層檢查的目的是保證保護(hù)涂層的質(zhì)量標(biāo)準(zhǔn)滿足 PSPC 的最低要求 It is recognized that in practice it is almost impossible to obtain a perfect coating that has no small imperfections even with the best execution of this standard Such perfect coating may only be possible under laboratory conditions With this in mind inspectors should have a common understanding of what is the acceptable minimum level of quality of protective coatings intended by the application of this standard 應(yīng)該清楚的是 實(shí)際的涂裝施工做到一點(diǎn)缺陷沒有是不可能的 應(yīng)是盡可能的實(shí)施該 標(biāo)準(zhǔn) 完美的涂層僅可以在實(shí)驗(yàn)室條件下實(shí)現(xiàn) 基于此 檢驗(yàn)員應(yīng)知道該標(biāo)準(zhǔn)在實(shí)施過程中的 最低可接受標(biāo)準(zhǔn) 確保該標(biāo)準(zhǔn)的實(shí)施 For example the check points for DFT measurements for the judgment of 90 10 rule are clearly indicated in annex 3 of PSPC but this cannot guarantee that 90 10 rule is perfectly achieved for the entire surface The common understanding is that such a sampling method is enough for making the judgment and if the sample measurements do not satisfy the criteria additional spot checks should be taken for any area considered necessary by the coating inspector 例如 PSPC 標(biāo)準(zhǔn)附件 3 中已經(jīng)明確描述了 90 10 規(guī)則干膜厚度測量取點(diǎn)方法 但還不 能保證 90 10 規(guī)則完全適應(yīng)全部的表面 統(tǒng)一的理解是這種取樣方法已經(jīng)可以進(jìn)行判斷 如果 有這種取樣測量方法不能滿足標(biāo)準(zhǔn)的要求的地方 檢查員可以在認(rèn)為需要的區(qū)域增加測量點(diǎn) Unless expressly provided otherwise in PSPC for example annex III and this Guideline inspection by sampling and statistical method should be adopted to the extent necessary for making practical judgment This means that the extent of inspection could vary depending on the quality control of shipyards to ensure that the required minimum level and quality is achieved 除了在 PSPC 標(biāo)準(zhǔn)和指南中已明確的部分外 可采用取樣檢測和統(tǒng)計(jì)的方法做出涂層質(zhì)量的判 斷 這意味著檢查的程度是各式各樣的 依靠船廠的質(zhì)量控制來保證達(dá)到 PSPC 標(biāo)準(zhǔn)要求的最 低質(zhì)量標(biāo)準(zhǔn) 5 5QualificationsQualifications 資質(zhì) 5 15 1 CoatingCoating InspectorsInspectors 涂層檢查人員 5 1 1 PSPCPSPC RequirementsRequirements
