This International Standard specifies the minimum requirements for billing of all consumption-based utility
network services to domestic customers. It covers the processes required to produce the bill and to deal with
issues that arise after the bill has been sent, as well as the content of the billing document or statement. This
International Standard is applicable to utility network services that are unmetered, metered at the point of
delivery or metered remotely (e.g. on the supplier's own premises), and it covers any unmetered or unmeasured
charges appearing on the same bill as metered or measured charges, as well as flat rate charges.
NOTE 1 Utility network services include electricity supply, water, sanitation, gas supply, district heating and
communications.
NOTE 2 The requirements given in this International Standard are also applicable to other consumers who are legally
entitled to use the service provided by the supplier, except where in order to comply with privacy or data protection
requirements, it is necessary for the supplier to obtain the authority of the registered customer before dealing with another
consumer on billing matters.
This International Standard does not cover pricing, except for a requirement to provide information to
customers. It is only applicable to billing for consumption-based utility network services and it applies to all bills
or statements for utility network services where there is an ongoing account relationship between the customer
and the supplier, regardless of the payment method used.
NOTE 3 This includes bills for metered consumption, bills where a formula is used to estimate consumption (e.g. water
bills based on the number of persons per household or the size of the house), or where a flat rate fee is charged regardless
of consumption (e.g. telephony or internet bills where the tariff allows unlimited usage). It also applies to prepayment
customers, where a bill or account from the supplier is necessary to enable the customer to reconcile the amount paid
in advance with the cost of consumption, or where the customer expects to receive a bill based on point of sale or other
advertising (e.g. mobile telephony and energy metering) where codes, keys, electronic dongles or electronic cards are
used to load and reload the service and to indicate what was purchased.
NOTE 4 Services that are not billed [e.g. mobile telephony paid for by pre-purchased SIM (Subscriber Identity Module)
cards that are unmetered] and services that are funded directly by the taxpayer without bills being issued are not covered
by this International Standard.
NOTE 5 Many of the key principles in this International Standard also apply to all forms of billing, and suppliers are
therefore encouraged to adopt the relevant requirements in this International Standard for billing of other services.

This part of IS0 2631 defines methods for the measurement of periodic, random and transient whole-body
vibration. It indicates the principal factors that combine to determine the degree to which a vibration exposure will
be acceptable. Informative annexes indicate current opinion and provide guidance on the possible effects of
vibration on health, comfort and perception and motion sickness. The frequency range considered is
- 0,5 Hz to 80 Hz for health, comfort and perception, and
- 0,l Hz to 0,5 Hz for motion sickness.
Although the potential effects on human performance are not covered, most of the guidance on whole-body
vibration measurement also applies to this area. This part of IS0 2631 also defines the principles of preferred
methods of mounting transducers for determining human exposure. It does not apply to the evaluation of extrememagnitude single shocks such as occur in vehicle accidents.
This part of IS0 2631 is applicable to motions transmitted to the human body as a whole through the supporting
surfaces: the feet of a standing person, the buttocks, back and feet of a seated person or the supporting area of a
recumbent person. This type of vibration is found in vehicles, in machinery, in buildings and in the vicinity of
working machinery.

ISO 2631-2:2003 concerns human exposure to whole-body vibration and shock in buildings with respect to the comfort and annoyance of the occupants. It specifies a method for measurement and evaluation, comprising the determination of the measurement direction and measurement location. It defines the frequency weighting Wm which is applicable in the frequency range 1 Hz to 80 Hz where the posture of an occupant does not need to be defined.
Whilst it is often the case that a building will be available for experimental investigation, many of the concepts contained within ISO 2631-2 would apply equally to a building in the design process or where it will not be possible to gain access to an existing building. In these cases, reliance will have to be placed on the prediction of the building response by some means.
ISO 2631-2 does not provide guidance on the likelihood of structural damage, which is discussed in ISO 4866. Further, it is not applicable to the evaluation of effects on human health and safety.
Acceptable magnitudes of vibration are not stated in ISO 2631-2.
The mathematical definition of the frequency weighting Wm is given in Annex A. Guidelines for collecting data concerning complaints about building vibration are given in Annex B.

It concerns mainly low-power generating sets driven by reciprocating internal combustion engines for the generation of single or multiphase alternating current or direct current up to 500 V. The generating sets are standard manufactured sets.
In this part of ISO 8528, "low-power" is taken to mean rated power of a magnitude up to approximately 10 kW/50 Hz, 12 kW/60 Hz. Low-power generating sets, for the purpose of this International Standard, are determined by the following special features:
- the users normally are laymen (for further details, see 3.1);
- the complete generating set is usually transportable or mobile;
- the electrical output is connected by means of plugs, sockets and screwed terminal except for extra low voltages;
- the generating set is ready for use without any additional installation work by the user.
Generating sets for special applications or of higher rated power conforming to the above special features may, by agreement between manufacturer and customer, be tested in accordance with this part of ISO 8528. If supplementary stipulations are required for certain applications, this is to be done taking this part of ISO 8528 as a basis.
