be demonstrated to produce repeatable results that will satisfy the acceptance criteria in this

specification.

如果表面清洗所用的清洗工艺的复检结果能够满足本文件中规定的验收标准，那么，这样的表面将

被视为符合氧气级清洗要求。

4.2When individual equipment item inspections for oxygen cleaning are not feasible or practical (e.g.,

for mass produced or commodity items such as cylinders, valves, or gaskets), Air Products might require that the cleaning process successfully pass an audit to the acceptance criteria in this

specification. Audits shall be conducted before first use and then periodically and whenever a

cleaning process is changed.

当对某单件设备进行氧气清洗检查不可行或不切实际时（例如钢瓶、阀门或垫片之类的大批量生产

的物件或商品），APCI可能要求清洗工艺必须成功地通过本文件验收标准的审计。首次使用之前

必须进行审计，然后定期审计，工艺改变时必须审计。

4.3Parts of assemblies shall be cleaned separately before assembling or fabricating renders any

surface inaccessible for cleaning or inspection. Pipe and fittings shall be cleaned before starting

fabrication.

4.7.2Mechanical input (e.g., agitation, scrubbing, pressure washing) is usually necessary for detergent

cleaning to be effective.

机械操作（例如搅拌、擦洗、压力清洗等）通常是有效地进行洗涤剂清洗所必不可缺少的。

4.7.3 Since detergent residues are not compatible with oxygen, detergent washing must be followed by

either thorough rinsing with potable water and thorough drying or by solvent cleaning.

由于氧气操作不容许有洗涤剂残留物，洗涤剂清洗后，必须用饮用水进行彻底漂洗并彻底干燥或者

用溶剂清洗。

4.8If Solvent Cleaning is Used

如果使用溶剂清洗

4.8.1Acceptable solvents are listed in Air Products 01.20.10. Alternatives must be approved by

Air Products in writing.

可接受的溶剂列在APCI 01.20.10文件中。替代品必须得到APCI 的书面批准。

4.8.2Proven methods of solvent cleaning include complete immersion, wiping with clean, lint-free rags

saturated with solvent, partial filling and rolling (for piping), and vapor degreasing.

公认的溶剂清洗方法包括完全浸没、擦洗、用蘸满饱和溶液的无绒布清洗、部分充装并滚洗（用于管道）和蒸汽去脂。

4.8.3Cleaned parts must be free of residual solvent. If for any reason (e.g., part geometry, solvent used,

cleaning method) the solvent does not readily evaporate from any surface of any part, the part

shall be purged with nitrogen [dew point -40?C (-40?F)] until all of the residual solvent has

evaporated. If heat is used to help evaporate solvents, precautionary measures shall be taken to avoid damage to seals, gaskets, and other soft goods.

清洗过的部件必须无残留溶剂。无论何种原因（例如部件的几何形状、所用的溶剂、清洗方法）导致任何部件表面上的溶剂不易蒸发时，必须用氮气[露点-40?C (-40?F)]吹扫部件表面，直至所有的

溶剂都被蒸发为止。如果用加热的方式来帮助溶剂蒸发，必须采用预防措施来避免伤害密封件、垫圈和其它软性部件。

4.8.4 Soft goods that could be attacked by solvents shall be removed before cleaning, then reinstalled

after cleaning.

在清洗前，要把可能受溶剂腐蚀的软性部件拆卸下来，清洗结束后重新安装。

4.9 If Blast Cleaning is Used

如果使用喷沙方式清理

The blast medium shall be <1% crystalline silica and hydrocarbon-free. Previously used grit shall not be reused.

喷沙介质必须是<1%水晶硅砂并且无碳氢化合物。不得重复使用以前用过的石英砂。

4.9.2The propellant shall be clean, dry, oil-free air or nitrogen, with a dew point of -40?C (-40?F).

驱动剂必须是干净、无油的空气或露点为-40?C (-40?F)的氮气。

4.9.3After cleaning, blasted components shall be blown out with propellant to remove all particulates.

4.10Pressure testing of assemblies, if performed after cleaning, shall be performed using filtered

potable water (as required to maintain required cleanliness) or dry, oil-free air or nitrogen at

ambient temperature. The degree of dryness of the pressure testing medium shall be sufficient to maintain established cleanliness. Equipment that is hydrostatically tested shall be thoroughly dried afterwards. Cleaning inspection and acceptance requirements will be applied after completion of the pressure test unless waived by the Air Products representative. This can be done where the

cleaning, assembly, inspection, and pneumatic pressure test are closely monitored and inspection after test completion is deemed not necessary.

如果组件需要在喷沙清理后进行压力试验，必须用过滤的饮用水（按要求保持必要的清洁度）或环境温度条件下的干燥、无油的空气或氮气进行清洗。压力试验介质的干燥度必须足以保持业已建立的清洁度。水压试验的设备必须在试验后进行彻底的干燥。试验完成后将按清洗和验收要求进行检查和验收，除非APCI 代表放弃这项要求。如果清洗、组装、检查和气压试验均受到密切的监控，那么，试验后检查被认为没有必要。

6. ACCEPTANCE CRITERIA

验收标准

6.1 Bright, White Light Inspection of components shall indicate:

组件的强烈白光检查必须显示：

6.1.1No moisture.

不潮湿。

6.1.2No cleaning agents. Particular care shall be taken to ensure that no residuals of cleaning agents

are left in dead ends or low spots of the system.

无清洗剂。必须采取特别的预防措施，确保系统的死角或低点无清洗剂残留物。

6.1.3No corrosion, scale, particulate matter, weld spatter, flux residue from welding or brazing, cutting

chips or foreign material such as sand or site debris. In general it is intended that "If you can

easily see the particle, the surface is not clean enough."

无腐蚀、结垢、颗粒物质、焊渣、电焊或钎焊焊药、切屑或者沙子或现场垃圾之类的外部物质。6.1.4No paint, crayon, or mill lacquer (unless painted surfaces are required by the job specification).

无油漆、油彩或轧钢厂油剂（工作标准中要求油漆表面的情况除外）。

6.1.5No hydrocarbon or organic material such as oil, grease, nonapproved adhesives and sealants.

Oxygen-compatible halocarbon lubricants are acceptable only if they are approved in writing by

Air Products. Excessive accumulations of oxygen compatible lubricants shall also be avoided.

无油、脂、未经允许的粘合剂和密封剂之类的碳氢化合物或有机物。只是在获得APCI 批准时，才可以使用氧气相容型卤代烃润滑剂。但是也要避免使用过量的氧气相容型润滑剂。

6.2Visual inspection of surfaces under UV light shall show:

UV光下的表面肉眼检查必须证明：

6.2.1No evidence of hydrocarbon fluorescence or significant quantities of textile fibers [greater than 75

particles per 0.1 square meter (1 square foot)]. Areas of low intensity fluorescence must be re-

examined visually and with a wipe test to determine acceptability. Certain materials such as some metal oxides, lint, and Oakite 444 fluoresce to a limited degree but are not harmful for Class AA cleanliness. Repeated examination and wiping should establish whether the questionable material is innocuous and can remain, or is harmful and must be removed. (Some small fibers may resist repeated cleaning and continue to fluoresce under UV light. Such a case shall be referred to the Air Products inspector.)

无碳氢化合物荧光或值得注意的织物纤维量[每0.1 平方米 (1 平方英尺)多于75颗粒]。低密度荧光区必须进行肉眼复检并进行一次擦拭试验以便确定是否可接受。有些物质（例如某些金属氧化物、纤维和Oakite 444）发出有限的荧光，但是，对AA级清洗解毒无害。复检和擦拭检查必须确定：有疑问的物质是无害的并且可以让其保留；或者是有害的并且必须予以去除。（有些微小的纤维可以抵抗反复的清洗，并且在UV光下继续发荧光。存在这种情况时，必须向APCI检查员报告。）

6.2.2Not all contaminants fluoresce under UV light. It might be necessary to determine the nature of

the contaminants likely to be present by virtue of the manufacturing or finishing processes and

perform control tests to determine whether such contaminants are detectable by UV light. If they

are not detectable, other methods (e.g., laboratory tests) must be used.

并非所有的污染物都会在UV光下发出荧光。可能有必须确定制造或光制过程中可能存在的污染物

的性质，并进行控制试验以确认这类污染物是否可以在UV光下测出。如果不可以测出，必须使用

其它方法检测（例如实验室试验）。

6.3Visual inspection by wipe test shall show:

擦拭试验的肉眼检查必须证明：

6.3.1No particles of any size or discoloration of the wiping medium, except that caused by oxidation of

the parent metal (i.e., rust "blush," gray or black aluminum oxide, or oxides of copper). Surfaces of

cast iron may also discolor the wiping medium because of the carbon element of cast iron.

无任何尺寸的颗粒或擦拭介质变色情况，母金属的氧化引起的变色除外（即锈“红色”、灰色或黑

色铝氧化物，或铜氧化物）。由于铸铁上存在碳元素，铸铁表面可能使擦拭介质变色。

6.3.2No evidence of oily residue on the wiping medium.

擦拭介质上无油类残留物的证据。

6.4 Indirect Inspection

间接检查

6.4.1Residues collected on filter paper from a test of inaccessible surfaces (see paragraph 5.4) shall

be examined under a bright, white light and shall indicate no accumulation of visible particles. The

surface of the wiping medium in contact with the solvent shall not be discolored, nor shall it

fluoresce.

不可接近表面试验中的滤纸上收集的残留物（见第5.4节）必须在强白光下检查，并且必须显示无

可见颗粒沉积。与溶剂接触的擦拭介质的表面不得变色，也不得发荧光。

6.4.2If laboratory analysis is the method of choice for a specific project, a level of 200 mg/m2

(20 mg/ft2) is considered an acceptable maximum for oil films. (See Appendix A)

如果实验室分析是某个特定项目的选择方法，最大可接受油膜量为200 mg/m2 。（见附录A）

installation of the component.

组件安装前，不得存在APCI 标准660.500所述的过量锈蚀。

7.POST CLEANING PROTECTION AND PRESERVATION

清洗后的保护和保持

7.1Immediately after acceptance, all equipment, piping, and component openings shall be provided

with durable, weather-tight seals such as commercially available plastic pipe caps or plugs to

prevent contamination.

验收后，要立即用商品塑料管帽或管塞之类的耐用防风雨密封件保护所有的设备、管道和组件件开

口，防止污染。

7.2Flange faces shall be protected from contamination and damage that might result from handling and

shipping. This may be accomplished by affixing a commercially available flange protector, placing a

0.1 mm (4 mil) polyethylene bag over the flange (provided that the outer surface of the flange is clean),

and sealing the bag to the pipe with tape. When there is potential for the bag to be damaged during

shipping, handling, or storage, flanges shall be fitted with bolted, 3 mm (1/8 in) thick metal covers with rubber gaskets.

法兰面要加以保护，防止搬运和运输期间可能引起的污染和损坏。可以通过给法兰装配一个商用法兰保护器、在法兰上覆盖一只0.1 mm (4 mil)的聚乙烯塑料袋（假设阀门的表面是干净的）并用胶带把塑料袋固定到管道上等方式，完成对法兰的保护。当运输、搬运或储存期间有可能损坏塑料袋时，必须用螺栓连接方式给法兰装配带橡胶垫的3 mm (1/8 in)厚金属保护罩。

7.3No tape or other adhesive shall be applied to any cleaned surface, including flange faces.

不得在任何已清洗的表面（包括法兰面）上使用胶带或其它粘合剂，

7.4All items used to seal openings shall be as clean as the item being sealed.

所有用来密封开口的密封件都必须与被密封部件一样干净。

7.5Small items may be sealed in 0.1 mm (4 mil) thick polyethylene bags. Each item shall be individually

bagged. Bagging and packing shall be such that all identifying marks on the item or affixed to the item

(e.g., manufacturer's part numbers, serial numbers, lot or heat numbers, Air Products' tag numbers,

purchase order numbers) can be read without opening the sealed bag.

小部件可以用厚度0.1 mm (4 mil)的聚乙烯塑料袋封装。每件物品都要有独立的包装。包装和装袋必须做到，部件上的所有标记或附在部件上的标记（例如制造厂的部件号、系列号、热处理批号、APCI标号、采购单号等）都能在不打开密封袋的情况下看清。

7.6Items that might rust if left exposed to the atmosphere shall, if practical, be purged of atmospheric

air and pressurized with nitrogen [dew point -40?C (-40?F)] to 0.07 bar g (1 psig) immediately after acceptance. If dry, oil-free nitrogen is not available or not permitted by the supplier for safety

reasons (e.g., asphyxiant hazard), dry, oil-free air may be used if the dew point can be guaranteed to be less than -40?C (-40?F). All openings (depending on the connection type) shall be sealed

with welded pipe caps/blanks, threaded plugs, or blind flanges to hold the pressure. The item shall be clearly identified as being pressurized with the pressurization medium also noted.

暴露在空气中可能锈蚀的部件，可行时，必须在验收后立即用常压空气吹扫，然后用氮气[露点为-

40?C (-40?F)]充压保护[氮气充至0.07 bar g (1 psig)]。如果干燥无油的氮气无货可供或者供货商出于安全原因（例如窒息危险）不允许使用氮气，若能担保空气的露点低于-40?C (-40?F)，可以使用干燥无油的空气。所有的开口（根据连接类型）都必须用焊接管帽/盲板、螺纹管塞或盲法兰密封以便保持压力。设备上必须清楚地标注压力介质。

7.7 To minimize rerusting and with the written approval of Air Products, carbon steel equipment may

be treated with Oakite NRP, a rust preventative for steel (see 670.201 for details).

为了最大限度地减少再锈蚀并且获得了APCI 的书面批准，可以用Oakite NRP（一种钢铁防锈剂）处理碳钢设备（详细情况见670.201）。

7.8 Items that might rust that cannot be pressurized shall be bagged or otherwise sealed to prevent

the entry of atmospheric air, and shall contain packets of silica gel, activated alumina, or a similar moisture-adsorbing agent secured inside the item preferably attached to shipping blanks (if

possible). The adsorbents shall contain a color indicator. Packets shall be connected in groups so they can be removed together. The item shall be clearly labeled as containing moisture

adsorbents, and the number of packets and their location shall be stated.

可能生锈但不可加压保护的部件，必须采用装袋或其它方法密封，防止常压空气进入，并且必须在部件内放置含硅胶、活性铝或类似吸湿剂的包装袋，最好放在运输间隔里（可能时）。吸湿剂中必须含有颜色指示剂。吸湿剂袋要连接成串，这样，就可以一起取出。部件上必须清楚地加注内含吸湿剂的标签，并说明吸湿剂袋数及其位置。

Exception: Adsorption packets are not required for packaged, control or manual valves.

例外：密封阀、控制阀或手操阀不需要加吸湿剂袋。

8. TAGGING
