General Company Policies

X-Ray Laboratories Ltd is a private limited liability company which has been in business since 1968 when it started business as Inrala Inspection Ltd. Inrala Inspection Limited was incorporated under the Companies Act 1995 as a Private Limited Company on the 26th April 1968, it changed it’s name to Industrial & Radiological Laboratories Limited on the 15th of April 1976, and then to X-Ray Laboratories Limited on the 25th of July 1984.

The current owners have been with the company since 2017, and have continued to support the business which had been operating since 1982. The company was the first and possibly the only NDT company outside Australia/PNG to get NATA registration which it held until the advent of Telarc and then IANZ. Current accreditation is with IANZ, and I Hughes is the Company Representative. The laboratory is available to all clients worldwide, although we tend to specialise in the northern North Island of New Zealand from Whangarei to Taupo. The company protects itself against legal liabilities primarily by providing only quality, accurate work over which there can be no dispute. We also have the protection of limited liability under the Companies Act 1955 with a fully paid up capital of $65,000.00. Public liability Insurance of $10M is carried, despite that with a quality programme risk is greatly reduced, and on principle we are not prepared to having less faith in our service than an insurance company.

Service To The Client

Some customers, particularly the Classification Societies such as Lloyds, ABS, BV etc require that their testing is witnessed. This is to be encouraged, because although the costs rise when testing times and output are slowed by additional preparation and co-ordination, there is an advantage to be gained from immediate approval of testing work, and unexpected issues can be addressed before committing a specimen to a destructive test. When this type of testing work is carried out the test area is cleared of other testing work or data to ensure the confidentiality of our work for other clients. If during testing it becomes obvious the specimens will fail before the completion of testing, the test technician is to inform the signatory, who will inform the client to receive further instructions. Any advice given to a client, whether formal or informal (other than a Test Report), is to be qualified as being non-expert personal opinion. X-Ray Laboratories Ltd is not an engineering or design consultancy and although a client may appreciate input from our technicians with experience in an area, they must get independent professional verification.


All information supplied by or obtained for a client is confidential to the client, except for information obtained by our laboratory which could affect public safety, and such information can only be released by the Manager to the appropriate authority, after advising the client of his intentions.

Conflict of Interest

In a service industry where we work for a number of competing companies, and where it is possible that we may compete with our own clients, very definite rules are applied to avoid a conflict of interest. X-Ray Laboratories Ltd do not carry out welder training or rent equipment for welder qualification testing as this would conflict with the work we do for private companies and technical training institutes, and government training institutes. We do not use companies or organisations which are in competition with us for services such as equipment calibration even if such a company is IANZ accredited, because in the unlikely event of a problem with calibration it could be reasonably expected by the client that we do not use companies or persons with a conflict of interest, and doing so could infer negligence and result in our company carrying full responsibility for problems that are largely out of our control.

Quality Assurance Policy Statement.

The formal quality assurance policy statement for X-Ray Laboratories Ltd, located at 43A Leonard Rd, Mt Wellington, Auckland, is prescribed in the Laboratory Manual which has been written to meet the ISO 17025 standard. It is the decision of the Company Director that X-Ray Laboratories Ltd shall supply to our customers the most cost effective service possible. Levels of inspection, as well as methods and forms of inspection, are to be dictated by the relevant design/construction code. Accuracy is to exceed, wherever possible, the necessary minimums prescribed by the applicable codes. Increased accuracy is not, however, to be confused with increased quality of any inspection service.

“Quality must be built into a product, not inspected in.” Higher accuracy or higher levels of inspection will not increase product quality. Products must be designed or selected fit for purpose and inspected to ensure they meet the design parameters. Extra inspection outside or above code requirements are only justified if they resolve ambiguities or “grey area” results, or when they are on the direct instruction of the customer.

It is the intention of this company to provided reliable, repeatable, and accurate test results at a reasonable cost in a competitive commercial environment. The procedures detailed in the Laboratory Manual are mandatory for all staff and subcontractors working through our company name and reporting format.

The Managers, Mr I Hughes & Mr S Burfoot, are responsible for the preparation of this manual.

IANZ Accreditiation

Currently IANZ accreditation is held in:

  • Class 4.75 Welder Qualification Tests
  • Class 4.76 Metals and Metal Products.
  • Class 4.79 Metallographic Tests on Metals
  • Class 4.81 Non Destructive Tests by Radiography
  • Class 4.82 Non Destructive Tests by Ultrasonics
  • Class 4.83 Non Destructive Tests by Visual Inspection
  • Class 4.85 Non Destructive Tests by Magnetic Particle Methods

Radiography reports are sometimes endorsed when required by the customer. It is usual and expected that this requirement is nominated at the time of placing the order, but because working methods do not differ between endorsed and non-endorsed work, the instruction to endorse a report can be accepted up until the time any initial or final report is delivered to the customer.

Very great care must be exercised if the radiography test methods are non-standard, whether by agreement with the customer or through their specific instruction. Only under exceptional circumstances, and with detail of the procedures and limitations on the test report itself, could such a report be endorsed.
