SP-55
FOREWORD The MSS SP-55, Quality Standard for Steel Castings for Valves, Flanges, Fittings, and Other Piping Components – Visual Method for Evaluation of Surface Irregularities, was originally adopted in 1961. It was developed for the purpose of providing the industry with a uniform means for identifying various types of casting surface irregularities. A set of 60 reference photographs illustrating these casting surface irregularities is included in this Standard Practice to permit a visual comparison of an actual casting surface with the reference photographs for the purpose of the establishing acceptable/unacceptable casting surface irregularities. The format of this Standard Practice was revised in 1996 to be consistent with other MSS Standard Practices. The 2006 revised edition included updates in the referenced standards, Annex A, to reflect current applicable dates and the updated addresses of the referenced publications organizations. organizations. This 2011 revised American National Standard edition includes updates to the applicable organizations and referenced standards, indicating current dates, names, and addresses of the referenced publications or organizations within this Standard Practice. In addition, an Annex B has been introduced that contains the preexisting set of 60 reference photographs, photographs, along with various editorial corrections that include Section 5.
IMPORTANT NOTICE: Due to variations in viewing environments, the printed version published by MSS shall be the “official” rendering of this Standard Practice for inspection, code, or any other purpose.

QUALITY STANDARD FOR STEEL CASTINGS FOR VALVES, FLANGES, FITTINGS, AND OTHER PIPING COMPONENTS VISUAL METHOD FOR EVALUATION OF SURFACE IRREGULARITIES
1. SCOPE 2.2 It is recognized that problems may be encountered in evaluating surfaces of castings over a wide range of size and section thickness using the same set of standards. This guide attempts to minimize the size effect and is intended for general use for any 4 in. x 5 in. (100mm x 125mm) area.
1.1 This Standard Practice is intended to supplement the requirements of ASTM Standard Specifications A216/A216M, A217/A217M, A351/A351M, A352/A352M, A389/A389M, A487/A487M, and A744/A744M, and to provide a series of reference photographs typical of the various surface irregularities common to steel pressure castings and illustrations of generally acceptable and generally rejectable quality. Table 1 of Section 5 is provided to show MSS interpretation as to the relationship between this Standard Practice and the levels of surface quality illustrated by the comparators and the associated photographs of the Castings Technology International (CTI), “Comparators for the Definition of Surface Quality of Steel Castings”.
3. REFERENCE PHOTOGRAPHS 3.1 A set of 60 reference photographs illustrating various casting surface irregularities, which can be observed by visual inspection, is included herewith (see Annex B). These photographs are actual size examples of gradations involving acceptable and non-acceptable irregularities. It is intended that irregularities less pronounced than those shown as non-acceptable shall be accepted under this guide.
1.2 For additional nondestructive examinations defining quality of steel castings, this Standard Practice may be supplemented by the following MSS Standard Practices: SP-53, “Magnetic Particle Examination Method”; SP-54, “Radiographic Examination Method”; SP-93, “Liquid Penetrant Examination Method”; SP94, “Ultrasonic Examination Method”; and SP-112, “Visual and Tactile Method”.
3.2 Photographs included are of actual castings and may exhibit surface irregularities other than the type characterized in the heading. Each type of surface irregularity shall be judged only against the series of photographs identified identified with the type. 4. TERMINOLOGY FOR REFERENCE PHOTOGRAPHS 4.1 It should should be noted that all definitions definitions and discussions of terminologies apply only to surface irregularities and not to internal defects. The types of surface irregularities illustrated in the reference photographs are as follows:
2. DEFINITION OF SURFACE QUALITY BY VISUAL INSPECTION 2.1 Twelve general types of surface irregularities are characterized in the collection (see Section 3) with five examples being included for each type. The two examples in each case shown to the left illustrate acceptable degrees of the particular type of irregularity. The three examples to the right are characterized as containing unacceptable defects.
a) Type I – Hot Tears and Cracks Linear surface discontinuities or fractures caused by either internal or external stresses or a combination of both acting on the casting. They may

occur during, or subsequent to, solidification. In general, visible surface cracks or hot tears, or both, are not acceptable.
j)
A void left in cast metal as a result of solidification shrinkage and the progressive freezing of metal, which is exposed upon cutting off risers and gates.
k) Type XI – Weld Repair Areas Evidence of improper preparation after welding. l)
Sand that becomes entrapped in the molten metal and shows on the surface of the casting.
Type XII – Surface Roughness
5. COMPARISON OF MSS SP-55 ACCEPTANCE CRITERIA WITH CTI COMPARATORS COVERING SURFACE TEXTURE QUALITY STANDARDS
d) Type IV – Gas Porosity Voids in cast metal caused by entrapment of gas during solidification.
5.1 MSS and other societies have published standards illustrating various levels of surface texture and irregularities classified by type.
e) Type V – Veining Features on the surface of castings appearing as a ridge and associated with movement or cracking of sand.
5.2 Table 1 has been included for the the purpose of showing MSS interpretation as to the levels of discontinuity by type, which would be met by castings conforming to MSS SP-55.
Type VI – Rat Tails
Features on the surface of castings appearing as a depression resulting from faulting or buckling of the mold surfaces.
5.3 The CTI Comparators are plastic replicas of actual casting surfaces, each of which is also represented by a photograph of the replica.
g) Type VII – Wrinkles, Laps, Folds and Cold Shuts
5.4 MSS SP-55 acceptance acceptance criteria have have been reviewed against the CTI Comparators to designate the acceptance criteria of each type, which are equivalent to MSS SP-55 acceptance criteria. Comparisons published in Table 1 represent the MSS interpretation. They are intended to be of assistance to those interpreting the CTI Comparators (1).
Surface irregularities caused by incomplete fusing or by folding of molten metal surfaces. h) Type VIII – Cutting Marks Irregularities in casting surfaces resulting from burning or mechanical means used in the cleaning of castings. i)
surface
Surface texture due to design, pattern, gating, and sand conditions.
c) Type III – Sand Inclusions
f)
Type X – Chaplets
Evidence of chaplets on surface of casting disclosing incomplete fusion, which likewise can apply to internal chills.
b) Type II – Shrinkage

Type IX – Scabs (1)
The CTI surface comparators for steel castings discussed in Section 5 do not identify specific levels as being acceptable. Such issues are left to the product specification or contract.
Slightly raised surface blemishes that are usually sand crusted over by a thin porous layer of metal.
