Full title and description

STB BS ISO 5667-21:2010 — Water quality — Sampling — Part 21: Guidance on sampling of drinking water distributed by tankers or means other than distribution pipes. The document gives practical guidance on planning and carrying out representative sampling when potable water is supplied or transported by tankers, vehicles, vessels or other bulk non-piped means, and on sampling during investigations, commissioning or emergency situations.

Abstract

ISO 5667-21:2010 establishes principles to be applied to techniques for sampling water provided for drinking and for use in the manufacture of food and beverages when that water is supplied by tankers or other non-contiguous bulk means rather than through a piped distribution system. It covers sampling at stages up to and including point of consumption or transfer to piped systems and addresses sampling from aircraft, trucks, trains, ships and other vehicles and containers; it also covers sampling in system investigations, commissioning and re‑commissioning and in certain emergency situations. The part explicitly excludes guidance on sampling of source waters, potable water from contiguous piped supplies (covered by ISO 5667-5), beverage products and drink vending machines.

Scope

This part of ISO 5667 provides guidance for sampling potable water that is supplied or stored by tankers and by bulk non‑piped means (including distribution and bulk storage on aircraft, trucks, trains, ships and other vehicles or containers). It is intended for sampling at any stage up to and including the point of consumption or transfer to a piped distribution system and for specific situations such as system investigations, commissioning and re‑commissioning and certain emergency responses (provided operative safety is not compromised). It does not cover sampling of source waters (e.g., groundwater, impoundments), potable supplies from contiguous piped systems (covered by ISO 5667-5), sampling of beverage products or food, or vending machines.

Key topics and requirements

• Principles for planning representative sampling programmes for potable water supplied by tankers and bulk non‑piped means.
• Practical guidance on sample collection from tankers, mobile storage, and bulk containers on vehicles and vessels.
• Considerations for sampling during commissioning, re‑initiation of long‑idle systems and system defect investigations.
• Health and safety guidance for sampling operatives in non‑standard or emergency situations.
• Clear exclusions: source water sampling, contiguous piped distribution sampling (ISO 5667-5), beverage product sampling and vending machines.

Typical use and users

Primary users include water utilities and tanker operators, environmental and public health regulators, laboratory managers and field sampling technicians, food and beverage manufacturers using delivered potable water, emergency response teams managing temporary water supplies, and consultants conducting system investigations or commissioning work. The standard is used to ensure representative, safe and traceable sampling where potable water is supplied or transported outside permanent piped infrastructure.

FAQ

Q: What is this standard?

A: ISO 5667-21:2010 provides guidance on sampling drinking water that is distributed or stored by tankers or other bulk, non‑piped means, covering practical sampling techniques, planning and safety considerations for those situations.

Q: What does it cover?

A: It covers the principles and procedures for representative sample collection and handling when potable water is supplied or transported by tankers, vehicles or vessels and during related activities such as commissioning, re‑initiation and system investigations; it excludes source water, piped distribution systems (ISO 5667-5), beverage product sampling and vending machines.

Q: Who typically uses it?

A: Water utilities, tanker and bulk water suppliers, environmental and public health agencies, laboratories and field sampling teams, the food and beverage sector (where delivered potable water is used), consultants and emergency response personnel.

Q: Is it current or superseded?

A: ISO 5667-21:2010 is the published edition from October 2010. According to ISO review records it has been reviewed and its status confirmed in ISO review cycles; draft work items to revise it (DIS) have been progressed in the past but were not published as a replacement at the time of the latest ISO records. Users should check national body catalogues or ISO updates for any very recent changes before relying on the standard for compliance work.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 5667 series (Water quality — Sampling). Other parts address programme design, sampling techniques, preservation and handling, sampling of piped drinking water (5667-5), ambient waters, wastewaters and specialised sampling contexts.

Q: What are the key keywords?

A: Drinking water sampling, tanker sampling, bulk water delivery, potable water, ISO 5667, sampling guidance, sample handling, distribution by vehicle/vessel, emergency water supply.
