ASTM Copper Strip Corrosion Standards37.1 These consist of reproductions in color of typical teststrips representing increasing

35、degrees of tarnish and corrosion,the reproductions being encased for protection in plastic andmade up in the form of a plaque.7.1.1 Keep the plastic-encased ASTM Copper Strip Corro-sion Standards protected from light to avoid the possibility offading. Inspect for fading by comparing two different pl

36、aques,one of which has been carefully protected from light (forexample, new plaque). Observe both sets in diffused daylight(or equivalent) first from a point directly above and then froman angle of 45. If any evidence of fading is observed,particularly at the left-hand end of the plaque, it is sugge

37、stedthat the one that is the more faded with respect to the other bediscarded.7.1.1.1 Alternatively, place a suitably sized opaque strip (forexample, 20-mm (34-in.) black electrical tape) across the top ofthe colored portion of the plaque when initially purchased. Atintervals remove the opaque strip

38、 and observe. When there isany evidence of fading of the exposed portion, the standardsshall be replaced.7.1.1.2 These plaques are full-color reproductions of typicalstrips. They have been printed on aluminum sheets by a 4-colorprocess and are encased in plastic for protection. Directions fortheir u

39、se are given on the reverse side of each plaque.7.1.2 If the surface of the plastic cover shows excessivescratching, it is suggested that the plaque be replaced.8. Samples8.1 In accordance with D 4057 or D 4177, or both, it isparticularly important that all types of fuel samples, that pass alow-tarn

40、ish strip classification, be collected in clean, dark glassbottles, plastic bottles, or other suitable containers that will notaffect the corrosive properties of the fuel. Avoid the use of tinplate containers for collection of samples, since experience hasshown that they may contribute to the corros

41、iveness of thesample.8.2 Fill the containers as completely as possible and closethem immediately after taking the sample.Adequate headspacein the container is necessary to provide room for possiblethermal expansion during transport. It is recommended thatvolatile samples be filled between 70 and 80

42、% of the contain-ers capacity. Take care during sampling to protect the samplesfrom exposure to direct sunlight or even diffused daylight.Carry out the test as soon as possible after receipt in thelaboratory and immediately after opening the container.8.3 If suspended water (that is, haze) is observ

43、ed in thesample, dry by filtering a sufficient volume of sample througha medium rapid qualitative filter, into the prescribed clean, drytest tube. Carry out this operation in a darkened room or undera light-protected shield.8.3.1 Contact of the copper strip with water before, duringor after completi

44、on of the test run will cause staining, makingit difficult to evaluate the strips.9. Preparation of Test Strips9.1 Surface PreparationRemove all surface blemishesfrom all six sides of the strip obtained from a previous analysis(see Note 1). One way to accomplish this is to use 00 grade orfiner steel

45、 wool or silicon carbide paper or cloth of suchdegrees of fineness as are needed to accomplish the desiredresults efficiently. Finish with 65-m (240-grit) silicon carbidepaper or cloth, removing all marks that may have been made byother grades of paper used previously. Ensure the preparedcopper stri

46、p is protected from oxidation prior to final prepara-tion, such as by immersing the strip in wash solvent fromwhich it can be withdrawn immediately for final preparation(polishing) or in which it can be stored for future use.NOTE 1Only final preparation (9.2) is necessary for commerciallypurchased p

47、re-polished strips.9.1.1 As a practical manual procedure for surface prepara-tion, place a sheet of silicon carbide paper or cloth on a flatsurface and moisten it with kerosine or wash solvent. Rub thestrip against the silicon carbide paper or cloth with a circularmotion, protecting the strip from c

Alter-natively, the surface of the strip can be prepared by use ofmotor-driven machines using appropriate grades of dry paperor cloth.D13004e139.2 Final PreparationFor strips prepared in 9.1 or newstrips being used fo

49、r the first time, remove a strip from itsprotected location, such as by removing it from the washsolvent. To prevent possible surface contamination during finalpreparation, do not allow fingers to come in direct contact withthe copper strips, such as by wearing disposable gloves orholding the strips in the fingers protected with ashless filterpaper. Polish first the ends and then the sides with the 105-mm(150-mesh) silicon carbide grains picked up with a pad ofcotton (cotton wool) moistened with wash solvent.
