Standards
This standard provides general guidance on the verification procedures to be applied when
carrying out penetrant inspection, in accordance with ISO 3452. These tests are intended to ensure that the
penetrant system is functioning correctly and that there has been no harmful
deterioration of the process materials during service. Generally, the frequency
of checking penetrant materials and black light sources will depend on the
frequency and conditions of usage. Specific and maximum intervals should be recommended
by the manufacturer.
.
This standard specifies the minimum requirements for industrial illuminators
used for viewing radiographs.
This standard lays down general
requirements on penetrant flaw detectors and their functional units which are
designed to reveal invisible, or poorly visible to the eye, surface
discontinuities in metals and non-metals of any geometry and at any stage of manufacture.
This part of GYS 120 specifies an ultrasonic testing method for
determining bond defects between the bearing metal and the backing. The test can be performed on metallic
multilayer plain bearings consisting of backings lined with bearing metal based
on lead and tin, with layer thickness greater than or equal to 0, 5 mm. The test is not possible within half the diameter
of the crystal from the edges of the bearing, oil holes, grooves, etc. because
of undefined reflections. In bearings with dovetail keying grooves at the bond,
the test may not be possible along the edges of the dovetails.
This part of ISO 4386 specifies a method of test for the determination of
the bond strength between the bearing metal and the backing. The test can be applied to multilayer plain
bearings with backings of steel, cast iron, or copper alloys and with bearing metal
based on lead, tin, copper, or aluminum with layer thickness of >
2mm. The test is suitable for production
control as well as for comparative investigations into the influence on the
bond strength of various processes and types of material for non-destructive ultrasonic
testing of the bond between bearing metal and backing for bearing metal layer
thickness > mm, See ISO 4386/1.
. This part of GYS
120 specifies a non-destructive penetrant testing for determining bond defects
and discontinuities in the sliding surface of the bearing. The penetration method
is used to detect - bond defects in the transitional area between the bearing
backing/bearing material on the end faces and joint faces of multilayer plain bearings which
cannot be detected by the ultrasonic testing method specified in ISO 4386- 1; discontinuities
in the sliding surface of the bearing. The penetration method is applicable, in
principle, to finished multilayer plain bearings.
This standard specifies requirements for full peripheral ultrasonic shear wave
testing of seamless and welded tubes for pressure purposes, with the exception
of submerged arc-welded (SAW) tubes, for the detection of longitudinal
imperfections according to four different acceptance levels (see table 1). This
standard is applicable to the inspection of tubes with an outside diameter greater
than or equal to 9 mm, and with an outside diameter-to-thickness ratio greater
than or equal to 5. For tubes with an outside diameter-to-thickness ratio less than
5, one of the methods specified in Annex A shall be used by agreement between manufacturer
and purchaser.
This part of ISO 10893 specifies requirements for automated full peripheral ultrasonic shear wave (generated by conventional or phased array technique) testing of seamless and welded [except submerged arc-welded (SAW)] steel tubes, for the detection of longitudinal and/or transverse imperfections.
Unless otherwise specified in the purchase order, the testing method is applicable to the detection of predominantly longitudinal imperfections.
In the case of testing on longitudinal imperfections, Lamb wave testing can be applied at the discretion of the manufacturer.
For seamless tubes, by agreement between the purchaser and manufacturer, testing principles of this part of ISO 10893 can be applied to detect imperfections having other orientations.
This part of ISO 10893 is applicable to the inspection of tubes with an outside diameter greater than or equal to 10 mm, normally with an outside diameter-to-thickness ratio greater than or equal to 5.
This part of ISO 10893 can also be applicable to the testing of circular hollow sections.
NOTE For options for testing tubes with an outside diameter-to-thickness ratio less than 5 on longitudinal imperfections, see Annex A.
This standard specifies requirements for eddy
current testing of seamless and welded tubes for pressure purposes, with the exception
of submerged arc-welded (SAW) tubes, for the detection of imperfections, according
to two different acceptance levels (see tables 1 and 2). It is applicable to the inspection of tubes
with an outside diameter greater than or equal to 4 mm.
This part of ISO 10893 specifies requirements for automated eddy current testing of seamless and welded tubes with the exception of submerged arc-welded (SAW) tubes, for the detection of imperfections according to the different acceptance levels as shown in Tables 1 and 2. It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm.
This part of ISO 10893 can also be applicable to the testing of hollow sections.
