SPECIFIC TECHNICAL REGULATIONS FOR TAXIMETER 1. PURPOSE The purpose of these technical regulations is to set metrological and technical requirements, metrological controls and test methods as well as test report format specific to taximeter. 2. SCOPE These technical regulations apply to taximeters that automatically calculate fares charged for journeys according to defined tariffs. These technical regulations do not apply to mechanical taximeters. 3. DEFINITIONS

3.1 “taximeter” means an equipment intended to measure duration and distance on the basis of a signal delivered either by a distance measurement transducer or global positioning system (GPS) and to calculate and indicate the fare to be paid on the basis of the measured distance and duration.

3.2 “taxi” means a vehicle, typically a car controlled by a driver that takes passengers on a journey in exchange for a fare.

3.3 “significant trip data loss” refers to instances when the measurement signal is lost to the extent that the taximeter cannot perform an accurate measurement or when the signal is not regained by the end of the trip. 4. UNITS OF MEASUREMENT a. Time: in seconds (s), minutes (min) and hours (h) b. Distance: in metres (m) or kilometres (km) c. Fare: in Rwandan francs (FRW) 5. METROLOGICAL REQUIREMENTS A taximeter complies with metrological requirements specified in RS OIML R21 (3). 6. TECHNICAL REQUIREMENTS

6.1 A taximeter complies with technical requirements specified in RS OIML R 21(4).

6.2 A taximeter calculates fares basing on either of the following: a. distance travelled; b. time elapsed; or c. a combination of distance travelled and time elapsed. 73 Official Gazette n° Special of 05/01/2024

6.2 Power Interruption, Electronic Taximeters a. After a power interruption of three seconds or less, the fare indications return to the previously displayed indications and may be susceptible to advancement without the taximeter being cleared. b. After a power interruption exceeding three seconds, the fare indications return to the previously displayed indications and is not susceptible to advancement until the taximeter is cleared.

6.3 Measurement Signal Loss In case the measurement signal is interrupted, the taximeter is capable of determining any information needed to complete a transaction in progress at the time of signal loss or interruption, and in case the meter ceases to increment fare based on distance, the taximeter may continue to increment fare based on elapsed time provided the time mechanism is not affected by signal loss.

6.3.1 Intermittent Trip Data Loss When the measurement signal is lost intermittently during a trip (e.g. traveling through a tunnel) but recovered prior to the end of the trip, the taximeter is capable of calculating an accurate fare.

6.3.2 Significant Trip Data Loss When the signal is lost for a significant portion of the trip, the taximeter calculates the total charge utilizing recorded time and distance measurements.

6.4 Anti-Fraud Provisions, Electronic Taximeters An electronic taximeter may have provisions to detect and eliminate distance input that is inconsistent with the taximeter’s source(s) of distance measurement data. When a taximeter equipped with this feature detects input inconsistent with the distance measurement data source(s), the taximeter: a. either filters out the inconsistent distance input signals or ceases to increment fare based on distance until the distance input signal is restored to normal operation. If the meter ceases to increment fare based on distance, the taximeter may continue to increment fare based on elapsed time when permitted by the statutory authority and when the time mechanism is not affected by inconsistent signals; b. provides a visible or audible signal that inconsistent input signals are being detected; and c. record the occurrence in an event logger. The event logger includes an event counter, the date and the time of at least the last 1000 occurrences. 74 Official Gazette n° Special of 05/01/2024 7. ELECTRONIC REQUIREMENTS A taximeter complies with the electronic requirements specified in RS OIML R 21 (5). 8. METROLOGICAL CONTROLS

8.1 Type approval A type or model of taximeter is subject to type approval before sale or use and complies with type approval requirements specified in RS OIML R 21 (6.2).

8.2 Initial verification A new taximeter of approved model is subject to initial verification before sale or use and complies with requirements specified in RS OIML R 21 (6.3).

8.3 Subsequent verification A verified taximeter is subject to subsequent verification every twenty-four (24) months after previous verification and complies with requirements specified in RS OIML R 21 (6.4). The maximum permissible errors at initial verification are considered.

8.4 Provision for Security Seals The taximeter becomes inoperable when access to the system’s metrological parameters is made through unapproved or unauthorized means. The device remains inoperable until cleared by the official having statutory authority.

8.5 Taximeter Connected to Networked Systems Metrological features that are not located on the taximeter device installed in the vehicle accessed through a computer network, server or “cloud” are secured by means that: a. protects the integrity of metrological data and algorithms used to compute fares from such data against unauthorized modifications; and b. uses software-based access controls or equivalent technological protections that limit access to metrological data and algorithms used to compute fares from such data only to authorized persons. Adequate provision is made for an approved means of security (e.g. data change audit trail) or physically applying security seals in such a manner that requires the security seal to be broken before an adjustment or interchange can be made of: a. any metrological parameter affecting the metrological integrity of the taximeter and associated equipment; or b. any metrological parameter controlled by software residing in the taximeter or an associated external computer network. 75 Official Gazette n° Special of 05/01/2024 An event logger must be used to record changes to adjustable parameters that are made through remote access and which is accessible only by authorized persons using an internet web browser or other such secure software. The event logger includes event counters, the date and time of the change, the parameter ID and the new value of the parameter. A printed or electronic copy of the information must be available through the device. The event loggers have a capacity to retain records equal to 10 times the number of sealable parameters in the device but not more than 1000 records are required.

8.6 In-service inspection A taximeter in use is subject to in-service inspection upon complaints or whenever considered necessary by the national metrology organ. The maximum permissible errors at initial verification are considered. 9. TEST METHOD A taximeter is tested in accordance with the test procedures specified in RS OIML R 21 (Annex A).

9.1 Taximeters using measurement data sources from other than rotation of the wheels Testing of taximeter with metrological significant parameters that do not completely reside within the taximeter device includes tests performed under variable conditions to verify that any non-compliant issue is generated from a network system rather than a single taximeter device. The variability tests include a minimum of three consecutive tests of varying lengths, locations or environment conditions.

9.1.1 Repeatability Testing Repeatability testing is conducted if, during testing, a taximeter registers a distance measurement that does not comply with the tolerance values. A minimum of three additional tests is conducted at the same location and where all test variables are reduced to the greatest extent practicable to verify the system’s ability to repeat transaction indications. Repeatability testing performed in excess of these three additional tests is done at the discretion of the official with statutory authority.

9.3 Taximeters Using Other Measurement Data Sources Except during type evaluation, all tests are performed under conditions that are considered usual and customary for the location(s) where the system is normally operated and as considered necessary by the statutory authority.

9.4.1 Testing for Environmental Influences During type evaluation, the distance test may be performed on a route travelled by the vehicle that exposes the system to conditions possibly contributing to the loss of, or interference with, the signal(s) providing measurement data. This may be: 76 Official Gazette n° Special of 05/01/2024 a. objects that may obstruct or reflect signals such as tall buildings/structures, forestation, tunnels, etc.; b. routes that do not follow a straight-line path; c. significant changes in altitude; and d. any other relevant environmental conditions. 10.

PURPOSE The purpose of these technical regulations is to determine the standard quantities and related pack sizes and controls required for pre-packaged products. 2. SCOPE These technical regulations apply to pre-packaged products labeled in predetermined constant nominal quantities of mass, volume, linear measure, area or count and sampling plans and procedures used in verifying the quantity of product in pre-packages. 3. TERMS AND ABBREVIATIONS

3.1 “pre-packaged product” means a single pre-packed item for presentation as such to a consumer, consisting of a product and the packing material into which it was put before being offered for sale and in which the quantity of product has a predetermined value, whether the packing material encloses the product completely or only partially but in any case in such a way that the actual quantity of product cannot be altered without the packing material either being opened or undergoing a perceptible modification.

3.2 “actual quantity” means quantity of product that a pre-package in fact contains as determined by measurements made by legal metrology officials.

3.3 “label” means any written, printed or graphic matter affixed to, applied to, attached to, blown onto, formed or moulded into, embossed on or engraved in or appearing upon a package containing any pre-packaged products for the purpose of branding, identifying or giving any information with respect to the pre-packaged products or to the contents of the package. 4. UNITS OF MEASUREMENT Units of measurement expressed in either words or symbols as provided in Table 1 apply. Table 1. UNITS OF MEASUREMENT Unit Symbol milligram mg gram g kilogram kg tonne t millilitre mL or ml centilitre cL or cl litre L or l micrometre μm 81 Official Gazette n° Special of 05/01/2024 millimetre mm centimetre cm metre m square millimetre mm2 square centimetre cm2 square decimetre dm2 square metre m2 cubic centimetre cm3 cubic decimetre dm3 cubic metre m3 5. STANDARD QUANTITIES AND PACK SIZES FOR PRE-PACKAGED PRODUCTS A pre-packaged product complies with standard quantities and pack sizes specified in Table 4 of these technical regulations. 6. METROLOGICAL REQUIREMENTS FOR PRE-PACKAGED PRODUCTS

6.1 Average requirement The average actual quantity of product in pre-packages is at least equal to the nominal quantity.

6.2 Individual pre-package requirements

6.2.1 The actual quantity of product in a pre-packaged product accurately reflects the nominal quantity but tolerable deficiencies (T1) are allowed.

6.2.2 A homogenous group of pre-packaged product contains no more than 2.5 % of packages having tolerable deficiencies (T1) errors.

6.3 T2 error No pre-packaged product has a T2 error.

6.4 Acceptance criteria An inspection lot is: a. accepted if it satisfies the requirements fixed for the three parameters above; or b. rejected if it does not satisfy one or more of the requirements.

6.5 Tolerable deficiencies For all pre-packages, the tolerable deficiencies (T) are specified in Table 2 below. 82 Official Gazette n° Special of 05/01/2024 Table 2. Tolerable deficiencies Nominal quantity of Tolerable deficiency (T) a product (Qnom) in g or mL Percent of Qnom g or mL 0 to 50 9 - 50 to 100 - 4.5 100 to 200 4.5 - 200 to 300 - 9 300 to 500 3 - 500 to 1 000 - 15 1 000 to 10 000 1.5 - 10 000 to 15 000 - 150 Above 15 000 1 - a T values are to be rounded up to the next 0.1 of a g or mL for Qnom less than or equal to 1 000 g or 1 000 mL and to the next whole g or mL for Qnom higher than 1 000 g or 1 000 mL. Nominal quantity of Percent of Qnom product (Qnom) in length Qnom ≤ 5 m No tolerable deficiency allowed Qnom > 5 m 2 Nominal quantity of Percent of Qnom product (Qnom) in area All Qnom 3 Nominal quantity of Percent of Qnom product (Qnom) in count Qnom ≤ 50 items No tolerable deficiency allowed Qnom > 50 items 1b b Calculate the value of T by multiplying the nominal quantity by 1% and rounding the result up to next whole number. The value may be larger than 1% due to the rounding but this is accepted because the products are whole items and cannot be divided.
