Indication, английский
- Индикация
- A situation or sign which suggests that a specific treatment should be given or that a condition has a particular cause sulpha drugs have been replaced by antibiotics in many indications. contraindication
- (1) notice given by a dealer (through autex) or customer of an interest in buying or selling stock, sometimes including specific volume and price; (2) approximation of where a specialist sees buy and sell interest to tighten the range to an opening price.
- Выражение интереса (бирж.)
- In nondestructive inspection, a response or evidence of a response, that requires interpretation to determine its significance.
- Nondestructive test response that requires interpretation to determine its relevance. these include such things as meter deflections, shadows on radiographs, blips on screens, or localized discolorations on surfaces. see also defect; discontinuity; indication, false; indication, nonrelevant. indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the significance of an indication. indication, false: test indication that could be interpreted as originating from a discontinuity where no discontinuity exists. compare defect; ghost; indication, nonrelevant. false indications are an economic liability for inspection because they must be investigated. indication, nonrelevant: indication due to misapplied or improper testing. may also be an indication caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation, or location.
- Nondestructive test response that requires interpretation to determine its relevance.4 see also defect; discontinuity; false indication; nonrelevant indication. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect.1 test response caused by geometry or by a physical condition that is not a discontinuity. indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.1
- Nondestructive test response that requires interpretation to determine its relevance. compare defect; discontinuity; indication, false; indication, nonrelevant. indication, false: (1) test indication that could be interpreted as originating from a discontinuity but that actually originates where no discontinuity exists in the test object. (2) indication due to misapplied or improper testing. compare indication, nonrelevant; defect. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect. test response caused by geometry or by a physical condition that is not a discontinuity (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.

- Nondestructive test equipment response to a discontinuity that requires interpretation to determine its relevance.4 in magnetic particle testing, a visible accumulation of magnetic particles that serves as evidence of a magnetic leakage field.
- Defect, discontinuity, false indication and nonrelevant indication. induced current magnetization: noncontact means for testing delicate ring shaped objects for circumferential discontinuities. the technique is based on the fact that a time varying current passing through an internal conductor, often a soft iron or laminated core, self-induces an encircling magnetic field. this time varying magnetic field will induce a secondary current circling through the ring. this secondary current then self-induces the toroidal magnetic field used for testing.
- Nondestructive test equipment response to a reflector, requiring interpretation to determine its relevance. compare crack; defect; discontinuity; indication, false.10 indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the indication’s significance.10 indication, false: test indication that originates where no discontinuity exists in the test object. compare defect; indication, nonrelevant.10 indication, nonrelevant: indication possibly caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance) or that is smaller than a relevant indication. compare indication, false and indication, relevant.10 indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation or location. compare indication, nonrelevant.10,19

Blending bleed back technique, английский
Procedure for verifying fluorescent penetrant indications by fully removing the indication and then reinspecting the area of interest. the technique begins by removing the indication using a soft paintbrush or cotton tipped applicator lightly moistened with a volatile solvent (for example, acetone). if the indication was linear, apply a light coating of solvent based nonaqueous wet developer to the area of interest. if the indication was nonlinear no developer is applied. the indication is confirmed if the fluorescent indication reappears within some time increment. also called doubt removal technique, rebleed technique, or wipeoff technique.
Bleed back technique, английский
In liquid penetrant testing, procedure for verifying fluorescent penetrant indications by fully removing the indication and then reinspecting the area of interest. the technique begins by removing the indication smoothly using a soft paintbrush or cotton tipped applicator lightly moistened with a volatile solvent (acetone). if the indication was linear, apply a light coating of solvent based nonaqueous wet developer to the area of interest. if the indication was nonlinear no developer is applied. the indication is confirmed if the fluorescent indication reappears within 600 s. also called doubt removal technique, rebleed technique or wipeoff technique.
