Guidance

Approved verification: guidance, application form and stickers

Weights and Measures Act 1985 and subsequent Deregulation Order 1999 (as amended).

Deregulation Order 1999 (as amended)

Section 11A of the Weights and Measures Act, introduced by the Deregulation (Weights and Measures) Order 1999, enables manufacturers, installers and repairers of weighing and measuring equipment to conduct verification tests on their own work, so that they can place items on the market or to return items to the market after a repair. This page contains information about the appointment of approved verifiers, installers and repairers as well as the ongoing maintenance of the systems that support their approval.

The Deregulation Order amended the Weights and Measures Act 1985. It allows manufacturers, installers and repairers of weighing and measuring equipment to apply to the Secretary of State for approval to conduct their own initial and in-service verification under section 11A of the Act. This entails confirming that equipment is fit for trade within the UK and stamping it with the prescribed stamp.

The Legislative Reform (Verification of Weighing and Measuring Equipment) Order 2008 further amended the Weights and Measures Act 1985 to extend the verification of prescribed equipment by approved verifiers to the activity of adjustment.

The approval system is underpinned by a requirement that the approved verifier possesses and operates an acceptable quality system. This must fully encompass the requirements of the legislation and the activities to ensure that equipment is correctly verified and necessary protection is maintained. Once granted approval, the approved verifier is subjected to regular audits. Approvals are granted for a specified time, are limited to specific equipment types and can be suspended or withdrawn if the approved verifier is found to be in breach of their approval conditions.

Verification stickers correspondence and pricing

Occasionally, Safety & Standards receives queries regarding verification stickers. The most common questions are:

How do I place an order for stickers?

Orders require a purchase order to be sent to Safety & Standards. Purchase orders must contain a purchase order number, details of the order required, invoice address and delivery address.

Purchase orders are to be sent to Metrology Stickers.

What are the prices for the stickers?

Notified bodies, approved verifiers and inspectors can claim an initial free sample of 20 stickers, but subsequent stickers have to be purchased. This is for both initial verification and requalification with the exception of inspectors whereby requalification stickers will be available free of charge.

With regards to the purchasing of the new metrology stickers, the prices and quantities will be as follows:

500 Stickers=£30+VAT

1000 Stickers=£50+VAT

2000 Stickers = £100+VAT

5000 Stickers= £250+VAT

10,000 Stickers= £500+VAT

Smaller amounts can be supplied but where less than 250 are required there will be a minimum charge of £10+VAT.

The disqualification stickers will be produced free of charge to all parties.

Delivery will be free of charge and posted second class. Please raise a purchase order stating quantity required and which sticker type along with notified body or inspector number.

How long does it take to produce the stickers?

Safety & Standards aims to have stickers produced and put in the post in 5 to 10 working days from receipt of your order.

How long will it take for them to be delivered?

Stickers are sent using royal mail second class postage. Orders that come to more than £250+VAT will be sent using royal mail second class recorded delivery.

Which stickers do I need?

Safety & Standards has produced guidance that identifies the format of stickers available for approved verifiers, chief inspectors of weights and measures, approved manufactures and notifed bodies. pages 63 to 66.

Reporting issues with approved verifiers

Safety & Standards provides a central point of reference for the reporting of incidents discovered by inspectors and verifiers of equipment relating to the processes controlled under NAWI and MID and the Deregulation (Weights and Measures) Order 1999, as amended. This informs the process of market surveillance under the EU directives and national provisions relating to weights and measures.

If you are an approved verifier, an approved manufacturer, a notified body or an inspector of weights and measures and have concerns about the way a piece of equipment was verified or conformity assessed by another organisation or the supporting processes, you can inform Safety & Standards by e-mailing information using the link below.

This reporting mechanism is not intended to deal with random errors relating to the accuracy of a single piece of equipment. Its purposes are to highlight systematic problems with quality systems and their associated processes, and to collect evidence to inform market surveillance.

Please supply enough information to ensure that the issue can be clearly identified and the companies’ processes and equipment involved are recorded.

This should include at least:

  • a brief description of the events
  • companies concerned
  • equipment involved or any identifying marks etc. that may help identification
  • the point at issue
  • if a notified body is involved, state which one
  • your contact details
  • any other action you are taking or persons you have informed
