Full title and description

ISO/TS 22492:2019 — Water pipe tobacco products — Determination of carbon monoxide emission of glowing water pipe charcoal — NDIR method. This technical specification defines a laboratory procedure using non‑dispersive infrared (NDIR) analysis to quantify carbon monoxide (CO) emitted from glowing water‑pipe (hookah/shisha) charcoal under specified test conditions.

Abstract

This document specifies a method for the determination of carbon monoxide (CO) emission of glowing water pipe charcoal. It sets out apparatus, sample preparation, calibration, measurement using an NDIR analyser, calculation procedures, and reporting requirements to produce reproducible CO emission results for comparative testing.

Scope

Specifies a laboratory method to determine CO emissions released from glowing water‑pipe charcoal (i.e., charcoal used to heat water‑pipe tobacco) using an NDIR analyser. The procedure covers sample handling, the test apparatus configuration, calibration of the CO analyser, test conditions to simulate glowing charcoal, measurement sequence, calculation of emission values and the format for reporting results. It is intended for testing charcoal products rather than smoke or vapour from the tobacco itself.

Key topics and requirements

• Definition of test specimen (glowing water‑pipe charcoal) and required conditioning before test.
• Required apparatus, including a non‑dispersive infrared (NDIR) CO analyser and sample chamber / flow system.
• Calibration procedures for the CO analyser (span and zero checks) and use of reference gases.
• Specified test atmosphere, flow rates and measurement timing to simulate glowing charcoal emissions reproducibly.
• Calculation methods for reporting CO emission (expressed according to the method’s prescribed units and reporting format).
• Requirements for documentation and reporting of test conditions, deviations and results to allow inter‑laboratory comparison.

Typical use and users

Used by product testing laboratories, charcoal manufacturers, water‑pipe (hookah/shisha) product developers, public‑health testing facilities, and regulators concerned with product safety and emissions. Typical activities include product compliance testing, comparative product evaluation, and research into emission reduction or consumer safety.

FAQ

Q: What is this standard?

A: ISO/TS 22492:2019 is a technical specification that describes a laboratory method using NDIR analysis to measure carbon monoxide emissions from glowing water‑pipe charcoal.

Q: What does it cover?

A: It covers apparatus, calibration, sample preparation, measurement procedure, calculation and reporting for CO emissions from glowing charcoal used with water‑pipe tobacco. It does not cover CO in tobacco vapour (that is addressed in ISO/TS 22491:2019).

Q: Who typically uses it?

A: Accredited testing laboratories, charcoal and water‑pipe product manufacturers, researchers, and regulatory agencies use the standard for product testing, compliance assessment and comparative evaluations.

Q: Is it current or superseded?

A: ISO/TS 22492:2019 was published in May 2019 (Edition 1). According to ISO’s record it was reviewed and confirmed (remains current) at the time of the latest ISO bibliographic update. Users should check the ISO catalogue or their national standards body for any subsequent amendments or a newer edition.

Q: Is it part of a series?

A: Yes — it is part of a group of technical specifications on water‑pipe tobacco products and emissions (for example ISO/TS 22491:2019 and ISO/TS 22487:2019) prepared by ISO/TC 126.

Q: What are the key keywords?

A: Key keywords include carbon monoxide, CO, NDIR, glowing charcoal, water pipe, hookah, shisha, emissions testing, ISO/TS 22492.
