BS ISO 6565-2015 PDF

Full title and description

STB BS ISO 6565-2015 — Tobacco and tobacco products — Draw resistance of cigarettes and pressure drop of filter rods — Standard conditions and measurement. This designation combines the international ISO document (ISO 6565:2015, 5th edition) with national adoption notation (BS ISO 6565:2015); "STB" in the title indicates a national designation applied alongside the BS/ISO number in some catalogues. The standard specifies standard conditions, apparatus and procedures for measuring the draw resistance of whole cigarettes and the pressure drop of filter rods.

Abstract

ISO 6565:2015 defines a laboratory method and the environmental/test conditions for determining the draw resistance (pressure loss during puffing) of cigarettes and the pressure drop across filter rods. It covers sample conditioning, instrument calibration, measurement procedure (vacuum and pressure instrument variants), expression of results and reporting of test data. The method is applicable to cigarettes, filter rods and similar cylindrical tobacco products.

General information

• Status: Published and confirmed (international standard; national adoptions exist such as BS ISO 6565:2015).
• Publication date: December 2015 (ISO publication implemented in December 2015 — ISO implementation date recorded 7 December 2015; BS national adoption shown as 31 December 2015). Confirmed on review in 2022 and current as of 23 February 2026.
• Publisher: International Organization for Standardization (ISO). National/adopted editions published by national bodies (example: British Standards Institution (BSI) for BS ISO 6565:2015).
• ICS / categories: 65.160 (Tobacco, tobacco products and related equipment).
• Edition / version: Edition 5 (2015).
• Number of pages: ISO published edition: approximately 20 pages (ISO layout). National/adopted versions (e.g., BS ISO) typically contain additional national foreword/identification pages and commonly show a larger total (example: BS ISO copies often listed as ~32 pages).

Scope

This standard specifies the standard atmospheric/test conditions, instrument calibration and a repeatable measurement procedure for (a) the draw resistance of finished cigarettes (measured under defined puffing/draft conditions) and (b) the pressure drop across filter rods. It is intended for use with cylindrical tobacco products similar to cigarettes and is intended to provide comparable, reproducible laboratory results between test laboratories and manufacturers.

Key topics and requirements

• Definitions and terms specific to draw resistance and pressure drop measurements for tobacco products.
• Standard test atmosphere and sample conditioning requirements (temperature and relative humidity control).
• Instrument types and calibration procedures for vacuum and pressure instruments.
• Detailed measurement procedure: sample insertion/encapsulation, flow or puff conditions, sequence of measurements.
• Calculation and expression of results (units in pascals and commonly reported conversions such as mmH2O), including repeatability and reproducibility guidance.
• Requirements for test reporting: sample identification, test conditions, instrument calibration records and measurement results.
• Precision data and inter-laboratory considerations (to support comparability of results).

Typical use and users

Used by tobacco product manufacturers, quality control and product development laboratories, independent test laboratories, regulatory and compliance bodies, and standards committees working on tobacco product test methods. Typical applications include incoming/raw material and finished product testing, R&D comparisons, production quality control and regulatory compliance testing where draw resistance or filter pressure drop are specified.

Related standards

Standards commonly referenced alongside ISO 6565 include: ISO 3402 (Atmosphere for conditioning and testing of tobacco products), ISO 10185 (Tobacco — Vocabulary), ISO 3308 (Routine analytical cigarette-smoking machine — definitions and standard conditions), ISO 4387 (Determination of total particulate matter — routine analytical smoking machine), and other ISO/TC 126 test-method standards for tobacco product analysis. National equivalents/adoptions (for example BS ISO 6565:2015) are also related.

FAQ

Q: What is this standard?

A: ISO 6565:2015 is an international standard that specifies how to measure the draw resistance of cigarettes and the pressure drop of filter rods under defined laboratory conditions. The title is often shown in national catalogues as BS ISO 6565:2015 when adopted by BSI; the user's heading included "STB" as a national/catalogue prefix that may appear in some listings.

Q: What does it cover?

A: It covers the required test atmosphere and conditioning, instrument calibration, step‑by‑step measurement procedures for both vacuum-style (cigarettes) and pressure‑type (filter rods) instruments, calculation and reporting of results, and precision information to support reproducible testing.

Q: Who typically uses it?

A: Tobacco manufacturers, product development and QC laboratories, independent testing houses, and regulatory agencies that need standardized, comparable measurements of draw resistance and filter pressure drop.

Q: Is it current or superseded?

A: ISO 6565:2015 is the 5th edition (published December 2015). The 2011 edition was withdrawn when the 2015 edition was issued. ISO records indicate the 2015 edition was reviewed/confirmed in 2022; as of 23 February 2026 the 2015 edition is the current ISO publication.

Q: Is it part of a series?

A: It is not a numbered series itself but is one of several ISO methods for tobacco test and analysis developed under ISO/TC 126 (Physical and dimensional tests and other analytical methods). It is commonly used together with other tobacco testing standards (for conditioning, smoking-machine methods and analytical determinations).

Q: What are the key keywords?

A: Draw resistance, pressure drop, filter rod, cigarette, conditioning, calibration, ISO 6565, tobacco testing, test method, BS ISO 6565.
