EN 1371-1 : 1997

BSI 1997

IntroductionThis European Standard complements the generalprinciples of liquid penetrant inspection given inEN 571 for the additional requirements of the foundryindustry.

Liquid penetrant inspection, as well as any other nondestructive examination method, is part of a general orspecific assessment of the quality of a casting to beagreed between the manufacturer and the purchaser atthe time of acceptance of the order.

Penetrant testing examination of castings isstandardized in two parts:

± EN 1371-1: Sand, gravity die and low pressure diecastings

± prEN 1371-2: Investment castings

1 ScopeThis European Standard applies to the liquid penetranttesting of all castings (except copper-tin and/orcopper-tin-lead alloy castings, where copper is themajor constituent) produced in conventional sandmoulds by gravity and low-pressure die casting,whatever their grade and the casting procedure used toproduce them.

This standard does not apply to investment andpressure die castings.

2 Normative referencesThis standard incorporates, by dated or undatedreference, provisions from other publications. Thesenormative references are cited at the appropriateplaces in the text and the publications are listedhereafter. For dated references, subsequentamendments to or revisions of any of thesepublications apply to this standard only whenincorporated in it by amendment or revision. Forundated references, the latest edition of the publicationreferred to applies.

NOTE. Informative reference to documents used in thepreparation of this standard, and cited at the appropriate places inthe text, are listed in a bibliography, see annex A.

3 Conditions for liquid penetrantinspectionThe manufacturing stage(s) when liquid penetrantinspection is to be performed shall be clearly definedby agreement between the manufacturer and thepurchaser.

Inspection shall be carried out only on those areas ofthe castings and on the percentage of castings agreed.Inspection requirements shall be clearly stated in thecall for tender, in the request for prices and, moreparticularly, in the order sent to the manufacturer andaccepted by him, so that the manufacturer can assessthe costs of manfacturing to satisfy the requiredseverity level and the costs of additional inspectionsand operations, and the manufacturing risks involved.

For each agreed area of the casting to be inspected,the following shall be indicated:

± type of discontinuity;

± severity level.

Sensitivity can differ depending on the method ofliquid penetrant inspection selected. Therefore theseverity levels required shall be selected as a functionof the liquid penetrants used and the method agreedbetween the manufacturer and the purchaser.

The type of discontinuity and the severity level canvary depending on the area of the casting inspected(see tables 1 to 3).

4 Method of inspection

4.1 Operating mode

Inspection shall be carried out as described inEN 571-1. The characteristics of the penetrant materialsshall be checked in accordance with specifications tobe agreed between the manufacturer and thepurchaser.

4.2 Qualification of the operators

Inspection shall be performed by personnel qualified inaccordance with EN 473 or by a certification schemewhich is considered to be equivalent. The qualificationlevel of the personnel shall be agreed between themanufacturer and the purchaser at the time ofacceptance of the order.

4.3 Surface preparation

The surface to be inspected shall be clean and freefrom oil, grease, moulding and coating residues or anyother contaminant which could interfere with thecorrect implementation and interpretation of thepenetrant inspection test results.

The surface finish of the casting in the area to betested shall have sufficient brightness and contrast ofcolour and adequate shape to determine the requiredseverity level. Unless otherwise specified at the time ofordering, the surface finish shall be selected fromtable 4.NOTE. It is recommended that the assessment of surface finish iscarried out using a visual cast-surface roughness comparator.

1) Shot blasting is not recommended prior to liquid penetrant testing.

Liquid penetrant inspection shall be performed oncastings in the as-delivered conditon. If sand blastingor shot blasting 1) is required, it shall be as light aspossible, in order to avoid sealing or closing uppossible discontinuities. If the risk of sealing or closingup possible discontinuities is unacceptable, thenblasting shall be followed by chemical etching in orderto enable detection of discontinuities. The chemicalcomposition of the etching bath and other parameterssuch as concentration, temperature, immersion time,neutralizing and rinsing, if applicable, shall berecorded.

4.4 Conditions of inspection

The inspection shall be carried out with the naked eyeor at a maximum magnification of 3 and viewingconditions in conformity with prEN 1956.

5 Acceptance criteria

5.1 Indications of discontinuities

5.1.1 General

The indication of discontinuities can be non-linear(isolated or clustered), aligned or linear. Althoughliquid penetrant inspection cannot generally be used todetermine the size of detected discontinuities, it allowsdiscontinuities to be assessed by measurement of thelength L of the indication. In the following clauses:

± L indicates length;

± W indicates width;

± t indicates section thickness;

± P indicates liquid penetrant;

± SP indicates non-linear isolated indication;

± CP indicates non-linear clustered indication;

± AP indicates aligned indication;

± LP indicates linear indication.

5.1.2 Criteria

The various types of penetrant indication cancorrespond to the discontinuities (A, B, C, etc.) shownin table 1.

The physical discontinuities detailed in table 1 shallgive either a non-linear, linear or aligned liquidpenetrant inspection indication.

5.2 Definition of liquid penetrant inspectionindications

a) linear indication (LP). An indication with thelargest dimension three or more times its smallestdimension (i.e. L $ 3W);

b) non-linear indication. An indication with thelargest dimension less than three times its smallestdimension (i.e. L < 3W):

± isolated (SP);

± clustered (CP): area of multiple indications, thedistance between the indications cannot bemeasured (they seem to form only one indication);

c) aligned indication (AP). Indications that areeither:

± linear: the distance between two indications issmaller than the length of the longest discontinuityin the alignment; or

± non-linear: the distance between two indicationsis less than 2 mm and at least three indications arenoted.

5.3 Severity levels

5.3.1 General

Several severity levels are recognized in accordancewith tables 2 and 3. It is necessary to carry out the teston a surface corresponding to a given degree of finish(see table 4) depending on the severity level desired.

The liquid penetrant inspection for each type ofindication and its severity levels shall be specified atthe time of ordering, by the purchaser, depending onthe use of the castings. The manufacturer shall give hisagreement.

The penetrant indications to be taken into accountshall have dimensions in accordance with the severitylevel.

The required severity level shall be selectedaccordingly and specified in the order by agreementbetween the manufacturer and the purchaser.

5.3.2 Criteria

The maximum permissible length for linear or alignedindications varies with the section thickness t. Threesection thickness types are specified (see table 3):

± type a: t # 16 mm;

± type b: 16 mm < t # 50 mm;

± type c: t > 50 mm.

Tables 2 and 3 show the largest dimensions of thesmallest indications to be considered in the severitylevel concerned.

5.3.3 Tables

Table 2 corresponds to non-linear isolated or non-linearclustered indications.

Examples of non-linear indications are shown inannexes B and C. These have been established inaccordance with table 2; the reference figures are givento and shall be interpreted against a scale of 1:1.

Table 3 corresponds to linear or aligned indications.

Tables 2 and 3 are independent (differing severity levelsmay be selected from these tables).

2) ISO format A6. If the casting dimensions in total are smaller than 105 mm 3 148 mm, then the indicating criteria should be inproportion to the surface area and agreed between the manufacturer and the purchaser.

6 Classification of the indications andinterpretation of resultsIn order to classify an indication of discontinuity, aframe measuring 105 mm 3 148 mm 2) should be placedin the most unfavourable location. The observedindications shall be in relation to the reference severitylevels as described in this standard and compared tothe equivalent or immediately better severity level.

Indications shall be considered to be equivalent when thesame number of non-linear spots and/or the same lengthof linear indications of similar appearance are detected.Maximum permissible discontinuities may appearsimultaneously on the area of 105 mm3 148 mm2).

If, for any indication type, the observed severity level isworse than that specified in the order, the casting shallbe considered to be in non-conformance with thisstandard. It shall be considered as conforming withthis standard when the observed severity level is equalto or better than that specified in the order.

For severity levels 1, 2, 3, 4 and 5, classification shall bemade by comparison with reference figures. Forseverity levels 001, 01, 02 and 03, and in the event ofdispute in the interpretation of severitylevels 1, 2, 3, 4 and 5, reference shall be made to thevalues in tables 2 and 3.

NOTE 1. Reference figures corresponding to non-linear, alignedand clustered indications in accordance with tables 2 and 3 arerepresented in annexes B, C and D for guidance only, drawn to ascale of 1:1.

The requirements detailed in the order or in thespecifications shall be written in conformance to theterminology used in this standard.

Examples of how the requirements shall be specifiedare as follows:

± non-linear indications level 2 (abbreviated as SP 2);

± linear and aligned indications level 5 (abbreviatedas LP 5c and AP 5c).

NOTE 2. `c' in LP 5c means that the section thickness type t isgreater than 50 mm.

NOTE 3. Severity level references are arbitrary. They cannot beconsidered in the same progression from one table to the other,nor from one kind of indication to another.

NOTE 4. Provided that, on the casting surface, no tested areacontains discontinuities which exceed the agreed severity level,there is no limit to the acceptability of discontinuities.

7 OrderingThe enquiry and/or order shall specify the followingpoints:

a) the area(s) of the casting(s) and percentage ofcastings to be inspected (see clause 3);

b) the manufacturing stage or stages when theinspection is to be carried out, as agreed betweenthe parties (see clause 3);

c) the type of discontinuity indications and theseverity level for each area of the casting(s) to beinspected (see clause 3 and 5.2).

8 RetestingRetesting shall be in accordance with EN 571-1.

9 Post-examination cleaning proceduresPost-examination cleaning procedures shall be inaccordance with EN 571-1.

10 Inspection documentationInspection documentation shall be in accordance withEN 571-1. A model of a trilingual inspection documentis shown in annex E.
