1.0 Purpose
The purpose of this bulletin is to establish the policy regarding replacement electronic indicators typically referred to as “Loaners” and “Spares”. These are generally placed into service when the scales original indicator has malfunctioned and is removed temporarily for repair.
2.0 Scope
This bulletin is applicable only to short term temporary loaner indicators and spare indicators, not to permanent replacement indicators.
3.0 Background
This bulletin was developed to allow service companies some latitude to place devices back into service quickly after a component failure. Prior to this, if an indicator malfunctioned, the trader would be forced to wait until a Measurement Canada inspector was available to conduct an initial inspection on the new indicator, even though the service company may have been able to complete repairs much sooner.
4.0 Loaner Indicators
A loaner indicator is a pre-inspected indicator owned by the scale service company and ‘loaned’ to the device owner as a temporary replacement unit. The loaner indicator is not intended to be a permanent replacement for the malfunctioning indicator.
4.1 Inspection and Markings
The following conditions must be met to prepare an electronic indicator for use as a loaner indicator:
4.1.1 The indicator must be Initially Inspected by Measurement Canada or an Authorized Alternate Service Provider.
4.1.2 The indicator shall be marked with its capacity in terms of number of scale intervals to which it has been inspected (n). n = Max / e.
4.1.3 The indicator shall be clearly marked as a “Loaner” device
4.1.4 The indicator shall be marked with the name and address of the service company to whom it belongs.
4.2 Installation and Use
The following conditions must be met for a loaner indicator to be temporarily placed into service as a replacement for a malfunctioning indicator:
4.2.1 The loaner indicator must be compatible with the scale to which it will be installed.
4.2.2 The loaner indicator shall be configured with the same verification scale interval (e) as the indicator which it replaces.
4.2.3 The loaner indicator shall be configured with the same weighing capacity (Max) as the indicator which it replaces.
4.2.4 The resulting number of scale intervals (n) must be equal to or less than that for which it was certified.
4.2.5 The resulting number of scale intervals (n) must fall within the parameters of the accuracy class for which it was approved, if applicable.
4.3 A loaner indicator can only be used as a replacement for a previously inspected indicator.
4.4 The company which installs the loaner indicator must test the device, with appropriate standards, to ensure its accuracy and then attach appropriate seals to deter tampering.
4.5 The installation of a loaner indicator must be reported to Measurement Canada, in writing, within 5 days of the installation as required by section 41 of the Regulations. Furthermore, Measurement Canada must be informed of the estimated date when the original, or a permanent replacement, indicator will be put back in service.
4.6 The loaner indicator and existing load receiving element will be subject to all of the requirements of the Weights and Measures Act, Regulations and Specifications, including normal enforcement action, when inspected.
4.7 Should a loaner indicator be taken out of “loaner” status to be installed on a permanent basis, a new inspection must be performed. All provisions of the Regulations and Specifications are applicable. The scale markings shall be corrected and the “loaner” designation, as required by section 4.2.3, removed.
4.8 Any company failing to comply with the stated conditions will be required to make arrangements for initial inspection of all indicators.
5.0 Spare Indicators
Spare indicators are those indicators inspected as backup devices for critical weighing operations. They are intended for use only on the device for which they have been originally inspected.
In order to allow the use of Spare Indicators, the following conditions must be met:
5.1 The spare indicator must be Initially Inspected by Measurement Canada or an Authorized Alternate Service Provider.
5.2 Only one spare indicator will be allowed per load receiving element.
5.3 Spare indicators may only be used with the load receiving element they were originally intended to be used with.
5.4 Spare Indicators must be inspected with the load receiving element with which they are intended to be used.
5.5 Spare Indicators are subject to all of the requirements of the Weights and Measures Act, Regulations and Specifications, including normal enforcement action, when inspected.
5.6 Spare indicators must be configured with the same verification scale interval (e) and Max as the primary indicator.
5.7 Spare Indicators must be suitably marked to allow for unambiguous identification of the load receiving element for which they are intended to be used.
5.8 Spare indicators must be available and tested each time the load receiving element or primary indicator is tested, calibrated or inspected.
6.0 Revision
The purpose of this revision is to:
a) clarify the requirements for loaner indicators
b) add requirements for spare indicators
c) reformat the Bulletin
