Relevant Indications: Indications with major dimensions greater than 1.5 mm (1/16 in.) shall be considered relevant.Read More
QS-36442 REV A Page 3 Master copy is maintained on line – uncontrolled if printed 1.0 SCOPE 1.1 This document defines the workmanship standards for suppliers and internal departments.The test acceptance criteria can therefore be subjective and need to be clearly defined for any set situation. Comparison of 316, 304 and 430 type stainless steels in salt spray testing Results from one testing laboratory, based on tests done to the ASTM B117 method suggest a 316 type part could be expected to pass a 96 hour test using a 3% ...Read More

The standard also allows stainless steel brushing to remove surface deposits or else for the surface to be left "as welded". These options are included in Condition III. Table 6.2.1 summarises the paths to the surface conditions and Table 6.3.3 provides the acceptance criteria based on discolouration, average surface roughness Ra and ...New construction of piping systems requires some type of cleaning of debris or contaminants. Debris can be defined as substances such as dirt, grease, construction materials such as wood, wire, hard hats, tools, weld slag, rust and scale, and any other small objects that could be misplaced inside the diameter of piping systems.Read More
What is the acceptance criteria for Sheet metal fabrication processing? 1. The flatness of the bottom surface of the box and other sides is 1mm. 2. The verticality of the box front and rear or left and right facades is 1mm. 3. The parallelism of …The acceptance criteria shall be: • No pitting on the internal nor external surface is acceptable at 20 X magnification. • Weight loss shall not exceed 4,0 g/m2. 5.3.8 Microstructural Examination Test samples for stainless steel Type 22 and 25Cr duplex shall comprise the weld metal,Read More
Acceptance criteria of Hardness and charpy test - ASME - UHA-51, UG-84 - Impact testing for stainless steel - ASME ...
Acceptance for visual standards will be based upon surface appearance only, exclusive of rms or AA values and without consideration of magnetic particle, fluorescent penetrant, radiographic, or other nondestructive testing requirements for findings.For austenitic stainless steel equipment the test water is limited to less than 250 weight ppm chloride ion with a pH between 6 and 9. Usually potable water meets this requirement. For high pressure service, above about 100 barg, less than 50 weight ppm chloride ion is required. All such equipment should be drained immediately after test and ...Read More

The diagram is more accurate than the Schaeffler diagram for duplex stainless steel alloys and ferrite contents to 100 FN. It …B. Acceptance criteria (e.g. ASTM E 186 severity level 2, or MSS SP-54-1995). 5. Any other information that might contribute to the production and use of the part. To produce a part by any manufacturing process it is necessary to know the design of the part, the material to be used and the testing required.Read More
blister. Acceptance criteria's for the test results are generally customer specified. Free iron detection tests and evaluations The above two types of evaluations (NSS and environmental), cabinet corrosion testing can also be very effective as free iron detection tests. Free iron testing is an excellent predictor of corrosionAs such, specifications for imperfections like surface roughness, pit diameter, pit density, scratch depth, and scratch length are provided. Manufacturers adopt the acceptance criteria defined in the ASME codes and standards to aid in new equipment acceptance activities.Read More

It plainly describes conditions under which the user requirements are desired thus getting rid of any uncertainty of the client's expectations and misunderstandings.Read More
Because of the extensive testing required and time consuming nature, these tests are generally not used for production testing, even when acceptance criteria are provided. ASTM Specification A923, Test Methods for Detecting Detrimental Intermetallic Phase in Duplex Austenitic/Ferritic Stainless Steels, has become the standard acceptance test ...This code covers the requirements for welding stainless steel components other than pressure vessels or pressure piping. For many years, fabrications involving stainless steel welding have used AWS D1.1/D1.1M, Structural Welding Code— Steel, to provide the requirements for quality construction. However, as the AWS D1.1 document is written for ...Read More
