ISO/DIS 13137:2021(E)
Introduction

Many different methods are used to determine the concentration of chemical and biological agents in

workplace air. Many of these methods involve the use of a pump and sampler connected by a flexible

tube. Air is drawn through the sampler and chemical and biological agents are trapped, e.g. on a filter,

sorbent tube or long-term detector tube, or in a gas washing bottle. In personal sampling, the pump and

sampler are attached to the worker so as to collect chemical and biological agents in the breathing zone.

The volume of air drawn by the pump during the sampling period is one of the quantities in the

calculation of the concentration of the chemical and biological agents in air. Therefore, the volume

of air sampled should be determined accurately and, in order to facilitate this, the flow rate should

be maintained within acceptable limits throughout the sampling period. For particle size selective

sampling, the short-term fluctuation of the flow rate should also be maintained within acceptable limits

in order to ensure that the sampler exhibits the required collection characteristics.

[1]

ISO 20581 specifies general performance criteria for methods for measuring the concentration of

chemical and biological agents in workplace air. These performance criteria include maximum values of

expanded uncertainty that are not to be exceeded under prescribed laboratory conditions. In addition,

the performance criteria should also be met under a wider variety of environmental influences,

representative of workplace conditions. The contribution of the sampling pump to measurement

uncertainty should be kept to a minimum.

This International Standard is intended to enable manufacturers and users of personal sampling

pumps to adopt a consistent approach to, and provide a framework for, the assessment of the specified

performance criteria. Manufacturers are urged to ensure that pumps meet the requirements laid down

in this International Standard, including environmental influences which can be expected to affect

performance.

1 Scope

This International Standard specifies performance requirements for battery powered pumps used for

personal sampling of chemical and biological agents in workplace air. It also specifies test methods

in order to determine the performance characteristics of such pumps under prescribed laboratory

conditions.

This International Standard is applicable to battery powered pumps having a nominal volume flow rate

above 10 ml ⋅ min , as used with combinations of sampler and collection substrate for sampling of

gases, vapours, dusts, fumes, mists and fibres.
This International Standard is primarily intended for flow-controlled pumps.

4 Type of pump
Sampling pumps are classified according to their intended use as follows:
— type P: pumps for personal sampling of airborne particles;
— type G: pumps for personal sampling of gases and vapours.

NOTE 1 Type P pumps can be used for personal sampling of gases and vapours as long as they comply with the

type G pump requirements.
NOTE 2 For types of pump mechanism and control system. see Annex A.
5 Requirements
5.1 Features
The pump shall have the following features:
a) an automatic control which keeps the volume flow rate nominally constant;

b) a means to reduce the likelihood of unintentional or unauthorized adjustment of any pump control,

such that it is concealed beneath a cover, can only be actuated with the aid of a tool or requires

specialized knowledge for operation;

c) either a malfunction indicator which, following completion of sampling, indicates that the air flow

has been reduced or interrupted during sampling, or an automatic cut-out which stops the pump if

the flow rate deviates by more than 5 % or is interrupted;

d) a fuse or resettable breaker which interrupts the current in the electrical circuit of the pump in the

case of excessive current drain;

e) a filter which prevents particles from being drawn into the mechanism of the pump;

f) a means to secure the pump on a person (integrated or available as an accessory).

NOTE 1 Some pumps use internal sensors to provide atmospheric, pressure and air flow data. Information on

the use of these sensors is given in Annex B.

NOTE 2 Among the test parameters described in this section, manufacturers shall test at least parameters

including operating time, long-term performance, pulsation of flow rates, time accuracy, and flow rate stability

under increasing pressure drop.
5.2 Mass

The mass of the pump, including batteries and integral holders, shall not exceed 1,2 kg for sampling

pumps with a flow rate of less or equal than 5 l ⋅ min and 2,5 kg for sampling pumps with a flow rate

above 5 l ⋅ min .
5.3 Design safety

The outer case of the pump shall be so designed that there are no sharp corners or other uncomfortable

protruding parts.
5.4 Operating time

The operating time shall be at least 1 h and should preferably be greater than 8 h. This applies to the

complete nominal flow rate range against the pressure drops as specified in Table 4 at (5 ± 2) °C. The

manufacturer shall report, in the instructions for use, the operating time at the specified pressure drop

according to 5.10 for the flow rates given in Table 1 at (5 ± 2) °C.

oSIST prEN ISO 13137:2021
ISO/DIS 13137:2021(E)

For the duration of the operating time, the flow rate shall not deviate by more than 5 % from the initial

value.

NOTE Annex C describes regular tests that users can perform to maintain pumps and flow meters. These

tests are not required for compliance with this document.
5.5 Start-up and long-term performance

During operation of the pump at (5 ± 2) °C and in the range from 20 °C to 25 °C, the flow rate shall not

deviate by more than 5 % from the value measured at the start of the determination of the long-term

performance.
5.6 Short-term interruption of air flow

When the air flow is fully blocked, the pump shall cut out or the malfunction indicator activate. The

pump may try to restart automatically after the airflow is blocked. If the air flow is blocked for more

than (120 ± 10) s, the pump shall not restart automatically or the malfunction indicator shall remain

activated until reset.

NOTE Some manufacturing sampling pumps are designed to restart automatically for a number of times

after being blocked. In this case, it is acceptable to restart automatically provided that the total time does not

exceed 120 ± 10 s.
5.7 Temperature dependence

When the flow rate is set within the temperature range from 20 °C to 25 °C in accordance with 7.7, it

shall not deviate by more than 5 % after cooling down the sampling train to (5 ± 2) °C within about

2 h and running for a period of (60 ± 1) min when the temperature is changed to the next (fixed) value

within the range from 5 °C to 40 °C as stated in 7.7.3.
5.8 Mechanical strength

The general function of the pump shall not be impaired by shock treatment (see 7.8). No mechanical

damage or electrical defect shall occur.

After shock treatment, the flow rate measured shall not deviate by more than 5 % from the value

measured prior to shock treatment.
