Working standards are standards that have been approved by Trading Standards for use by an Accredited Person when completing verification or inspection work.
These are standards that are to be verified on an annual basis or sooner, if required by Trading Standards or if the integrity of the standard has been jeopardised in any way. Standards are to be submitted for verification, as per the instructions outlined in the Verification by Trading Standards or the Verification not by Trading Standards sections below.
Once verified, they are to be listed in the Quality Management System (QMS) of the accredited organisation.
A standard that is not verified is not considered a working standard and therefore no verification or inspection work should be completed using it.
Standards that have not been approved as a working standard may only be used in specific circumstances. For example, non verified volume measures used to test a measuring instrument during a compliance audit or non verified masses used as makeweight during testing of a high capacity weighing instrument.
Verification by Trading Standards
Prior to any work being undertaken by a Trading Standards laboratory, the Accredited Person is required to submit a completed standards verification request form and have a booking confirmation from Trading Standards.
Please read the safe working practice document and complete the standards verification request form before contacting us:
The Accredited Person shall use the request form to provide a purchase order number, without which a standard will not be tested. Confirmation is also required to confirm that laboratory staff can adjust the standard, if it is found to be outside the legal tolerance.
When a standard is submitted for verification, it must be marked with their nominal value, an identification number/code, be clean, free from defect and, in the case of volumetric measures, free from fuel and contaminants.
If the standard does not meet Trading Standards requirements, the laboratory will decline to verify the standard, inform the organisation why the standard has been declined and may charge the organisation for the time involved.
For further information on requirements for working standard volume measures, see Technical Policy TS-027.
When the submission procedure is not followed or a standard is found not to meet our requirements, this may be deemed a breach of accreditation and action taken by Trading Standards, see non-compliances.
All working standards must be listed in the Quality Management Systems of an accredited organisation. If any working standards are added, removed, altered and/or replaced, the Quality Management Systems must be updated to reflect the change(s) made and submitted to Trading Standards for approval as soon as practicable.
Trading Standards will charge for accreditation related activities. The fee charged by Trading Standards is based on an hourly rate ($111.11/hour excluding GST). The hourly rate will include; time taken to conduct the verification, preparation time, plus any reimbursable expenses.
Accreditation costs has more information.
Verification not by Trading Standards
A standard may also be verified by another equivalent authority:
- Measurement Standards Laboratory of New Zealand (MSL), or
- By direct reference to a national standard of measurement in an approved overseas country.
Accredited Persons are advised to contact their Client Manager at Trading Standards, prior to having a standard verified by another equivalent authority, to confirm that the standard and verifier meet our requirements.
Change of ownership of working standards from one accredited organisation to another
The verification report for working standards specifies the accredited organisation who owns the standard. If there is a change of ownership of those working standards, the verification report becomes invalid.
Working standards are only accepted as such when under the care and custody of the Accredited Person, as identified in the verification report, and when listed as a resource within the Quality Management System of that accredited organisation.
Any new owner of the standard would have to resubmit the standard for verification, as outlined above.
In the situation where working standards are not in the care and custody of an accredited organisation for the duration of the verification period, i.e. stored at another location, this must be detailed in the Quality Management System, and the steps that will be taken by the organisation to maintain the integrity of the working standards must be stated.
