Inspections verification

Inspections by owner include inspections, verifications, and audits of the construction of piping systems, which include fabrication, welding, heat treatment, assembly, erection, examination, and testing, in addition to the construction organization s documented procedures, personnel qualifications, and quality control records.

The automatic acquisition and analysis system we developed within the scope of the Super-Phenix steam generator tube inspection by ultrasonic arrays is a remarkable example of an exhaustive acoustic verification system. It works for every type of probe for tube inspection. 

The results of corrosion surveys are received by the Surveyor in an agreed format using Forms TMl - TM8, preferably with the LR software freely issued to the approved firms. The report will highlight any areas where corrosion has gone beyond the permitted maximum diminution, which may be as low as 15% of the nominal thickness for a single item, and will also identify areas of "substantial corrosion T.e., any in excess of 75% of the permitted maximum. Corrosion in excess of that permitted means that the item has to be replaced. Any areas of corrosion deemed to be "substantial" are recorded for annual inspection. The Surveyor will review the completed report for verification and confirmation of the completeness of the thickness survey. 

After a satisfactory verification film is produced, an assembly may be fabricated specifically for destructive inspection to validate that the verification film was accurate. This correlation allows the use of verification film rather than more expensive destructive inspection for future changes such as duplicate tool fabrication and tool or detail modification. Simple assemblies are usually not destructively inspected because of high confidence that the verification film is entirely representative of the expected bondlines. Complex or large parts may not be destructively inspected because of the cost of the details and assembly time. In these cases other means of validating the verification film are used. Meticulous pre-bond detail and post-bond assembly thickness measurements may be sufficient to prove bondline thickness control. Ultrasonic inspection and X-ray photography (discussed previously) may be sufficient to prove that details are in the correct places and bonds are good. 

If an assembly is destructively inspected, the verification film is used to identify potential problem areas for particular attention. These areas and others randomly selected are cross-sectioned to determine bondline thickness (Fig. 22), bond details are peeled apart to inspect for voids and honeycomb core bonds are...

The design verification plan should be constructed so that every design requirement is verified and the simplest way of confirming this is to produce a verification matrix of requirement against verification methods. You need to cover all the requirements, those that can be verified by test, by inspection, by analysis, by simulation or demonstration, or simply by validation of product records. For those requirements to be verified by test, a test specification will need to be produced. The test specification should specify which characteristics are to be measured in terms of parameters and limits and the conditions under which they are to be measured. 

Verification of some characteristics may only be possible by calculation rather than by test, inspection, or demonstration. In such cases the design calculations should be checked either by being repeated by someone else or by performing the calculations by an alternative method. When this form of verification is used the margins of error permitted should be specified in the verification plan. 

The quality of the product can be verified by you witnessing the final acceptance tests and inspections on the subcontractor s premises. (If you don t possess the necessary equipment or skill to carry out product verification, this method is an economic compromise and should yield as much confidence in the product as the previous methods. You do, however, need to recognize that your presence on the subcontractor s premises may affect the results. They may omit tests which are problematical or your presence may cause them to be particularly diligent, a stance which may not be maintained when you are not present.)... 

The requirements pertain to your customer verifying product purchased by you either at your supplier or on your premises. Verification of purchased product is normally carried out by the supplier before or after receipt as part of the purchasing process but may also be carried out by the customer. However, due to the standard locating most of the inspection and test requirements in clause 4.10, the receipt inspection requirements are displaced. 

Controlled conditions include in-process monitoring and in-process inspection and test. All controls need a verification stage and a feedback loop. You cannot control production processes without performing some kind of verification. 

It should also not be assumed that these requirements are only intended for implementation by a department with the title Inspection or Test. Whenever a product is supplied, produced, or repaired, rebuilt, modified, or otherwise changed, it should be subject to verification that it conforms with the prescribed requirements and any deficiencies corrected before being released for use. That is what control means. Control is not just the inspection part of the process and hence quality control , which for years was the name given to inspection departments, was misunderstood. Inspection and test don t control quality. Inspection and test merely measure the quality achieved and pass the results to the producer for remedial action. 

The standard provides a choice as to whether you define the inspections and tests required in a quality plan or in documented procedures. You may of course need to do both. As the quality system is often designed to accommodate all products and services you supply, it may not specify inspections and tests which are needed for particular products. This is one of the roles of the quality plan. Within such a plan you should identify the verification stages during product development, production, installation, and servicing as applicable. These stages will vary depending on the product, so your quality plan will be product, contract, or project specific (see Part 2 Chapter 2). There may... 

The standard requires that the supplier ensures that incoming product is not used or processed (except in the circumstances described in 4.10.1.2) until it has been inspected or otherwise verified as conforming to specified requirements and requires that verification be in accordance with the quality plan or documented procedures. 

Part evaluation by accredited contractors or test laboratory provides independent verification which can substitute for your own receiving inspection, providing you maintain control over the contractor. 

To accomplish this, you need to specify either in the quality plan or the documented procedures, the inspections and tests you intend to carry out to verify that the product meets specified requirements. In Part 2 Chapter 4 there is a description of a Design Verification Plan and this includes a specification of the tests and inspections to be performed on each production item as a means of ensuring that the qualified design standard is being maintained. This requires that you produce something like an Acceptance Test Plan which contains, as appropriate, some or all of the following ... 

The standard requires a /ayout inspection and a functional verification to applicable customer engineering material and performance standards to be performed for all products at a frequency specified in the control plan. 

Your inspection and test records or verification records should be of two forms one which indicates what inspections and tests have been carried out and the other which indicates the results of such inspections and test. They may be merged into one record but when parameters need to be recorded it is often cleaner to separate the progress record from the technical record. Your procedures, quality plan, or product specifications should also indicate what measurements have to be recorded. 

Don t accept product back into the inspection flow without verification that previous inspection stages have not been invalidated. 

Devices that you use for product verification at all stages in the quality loop need to be controlled and this includes devices used for inspection and test on receipt of product, in-process, and final acceptance before release to the customer. It also includes devices used during design and development for determining product characteristics and for design verification. Some characteristics cannot be determined by calculation and need to be derived by experiment. In such cases the accuracy of devices you use must be con-... 

Should you not use measuring devices in your organization, these requirements will not apply. If your means of verification are limited to visual inspection or professional judgement, as is the case with organizations that deal only with documentation, you will have no devices to control. However, you may use tools or computer software to assist you to determine conformance and these will need to be proven capable of producing a reliable result. 

This requirement hides an important provision. It not only applies to inspection, measuring, and test equipment but to the measurements that are performed with that equipment. Anywhere you intend performing product verification or monitoring processes you need to ensure that the environmental conditions are suitable. By environmental conditions is meant the temperature, pressure, humidity, vibration, lighting, cleanliness, dust, acoustic noise, etc. of the area in which such measurements are carried out. To avoid having to specify the conditions each time, you need to establish the ambient conditions and write this into your procedures. If anything other than ambient conditions prevail, you may need to assess whether the measuring devices will perform adequately in these conditions. If you need to discriminate between types of equipment, the ones most suitable should be specified in the verification procedures. 

You are only required to indicate whether product conforms to the inspections and tests performed. This is not the same as indicating whether the product conforms to the customer requirements. It may well pass the prescribed inspections and tests but these inspections and tests may not be sufficiently comprehensive to verify conformance to all the customer s requirements. However, the only indication you can give is the product s conformance or nonconformance with some verification requirement. It follows therefore that you should not go around putting reject labels on products, or acceptance labels for that matter, if you have not performed a specific inspection to determine conformance. There are only three conditions uninspected , inspected and found conforming , and inspected and found nonconforming . If you have a policy of only applying labels after inspection, anything without a label is therefore deemed uninspected, unless it has been installed and the label removed.
