1 Scope

This European Standard specifies the test methods for verification of vapour recovery systems at service

stations (Stage II).

This European Standard does not specify the test method for the air and vapour tightness testing of the

vapour recovery systems at service stations.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated references,

the latest edition of the referenced document (including any amendments) applies.

EN 16321-1:2013, Petrol vapour recovery during refuelling of motor vehicles at service stations — Part 1: Test

methods for the type approval efficiency assessment of petrol vapour recovery systems

3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 16321-1:2013 apply.

4 Requirements for petrol vapour/petrol ratio

The petrol vapour/petrol ratio shall be equal to or greater than 0,95 but less than or equal to 1,05.

5 Measurement methods for in service tests
5.1 General

In this European Standard three test methods for verification of vapour recovery systems at service stations

are described. For any verification only one method shall be employed.

The in service verification test shall only be carried out at ambient temperature between +5 °C to +25 °C

under real or simulated petrol flow conditions.

Where it has been demonstrated that the combination of vapour recovery system and the verification

equipment operates to this standard at a temperature range beyond +5 °C to +25 °C, there shall be a

technical file which defines:
 how this has been achieved;
 justification for the test method;
 the upper and lower temperature limits for performing the verification.
This technical file shall be available.

The seals of the weights and measures components of the fuel dispenser shall not be broken.

For all tests, the instructions of the manufacturer of the vapour recovery system shall be followed.

---------------------- Page: 6 ----------------------
SIST EN 16321-2:2013
EN 16321-2:2013 (E)

Consult manufacturer's instructions for the location of the permanently fixed label, in accordance with

EN 16321-1, which contains the setting data relevant for the measurements (pulsing rate of the fuel dispenser,

correction factor, certificate number of the built-in vapour recovery systems, etc.).

After testing, the system shall be returned to normal operation.
5.2 Sequence of tests

For each nozzle of the vapour recovery system to be tested the ambient temperature shall be measured at the

start and end of the test sequence using a temperature measuring device, measuring range 0 °C to 40 °C and

an accuracy of maximum ± 1 °C. The temperatures shall be recorded.

If the temperature at the start of the test is outside +5 °C to +25 °C no test shall be carried out except where

the temperature is within the extended temperature range according to 5.1.

If the temperature at the end of the test is outside +5 °C to +25 °C the test results are not valid except where

the temperature is within the temperature range according to 5.1.

The test sequence for each nozzle shall be as set out below and given in Figure 1.

Where the test result meets the requirement of Clause 4 the nozzle shall be considered to pass the test. No

further test is required.

Where the test result fails to meet the requirement of Clause 4 the nozzle shall be retested.

Where the test result fails to meet the requirement of Clause 4 the nozzle shall be considered to have failed.

No further test is required.

Where the test result meets the requirement of Clause 4 the nozzle shall be retested.

Where the test result meets the requirement of Clause 4 the nozzle shall be considered to pass the test. No

further test is required.

Where the test result fails to meet the requirement of Clause 4 the nozzle shall be considered to have failed.

No further test is required.
The results shall be recorded.
