Full title and description

ISO 9073-16:2007 — Textiles — Test methods for nonwovens — Part 16: Determination of resistance to penetration by water (hydrostatic pressure). This part defines a hydrostatic pressure test to measure the resistance of nonwoven fabrics to water penetration under controlled hydrostatic head pressures, intended for nonwovens used as barriers to fluid penetration.

Abstract

ISO 9073-16:2007 describes the hydrostatic pressure test procedure, required apparatus and test conditions for determining the hydrostatic head at which water first penetrates a nonwoven specimen. The method is applicable to nonwoven fabrics intended to resist fluid penetration and specifies test rates, specimen preparation and reporting of results.

Scope

This part of ISO 9073 specifies a hydrostatic pressure test to determine the resistance of nonwoven fabrics to penetration by water. It applies to nonwovens intended for use as a barrier to fluid penetration and defines the principle of the test, specimen mounting, acceptable pressure increase rates, environmental conditioning and the criteria for defining the test endpoint (appearance of water penetration). The method is intended for routine laboratory evaluation and comparative assessment of water resistance properties.

Key topics and requirements

• Principle: clamp specimen over a test head reservoir and increase hydrostatic pressure until water penetrates; endpoint determined by appearance of drops or continuous leakage.
• Apparatus essentials: hydrostatic pressure apparatus with leak-tight clamping head and accurate pressure measurement; provision for specimen support (optional nets) and controlled pressure ramp rates.
• Test conditions: specified temperature/conditioning of specimens (standard laboratory conditions unless otherwise agreed) and use of clean water as the test fluid.
• Pressure application rates: defined rates (examples in the standard) to ensure reproducible determination of hydrostatic head at first penetration; rates and units reported (e.g., cm H2O or hPa).
• Specimen preparation and number: requirements for sample size, orientation and recommended number of replicate specimens for statistical reporting.
• Results and reporting: record individual values, mean, standard deviation and coefficient of variation; report test conditions, apparatus configuration and any deviations.
• Precision and calibration: follow appropriate metrology and calibration practices for pressure measurement and apparatus performance verification.

Typical use and users

Used by nonwovens manufacturers, independent textile and materials test laboratories, quality assurance teams, product developers and procurement/specification engineers who need to verify or compare water resistance (barrier) performance of nonwoven products (e.g., medical barrier fabrics, protective apparel, industrial wipes, geotextiles where fluid penetration resistance is relevant). Regulatory bodies and certification schemes may reference the method when assessing barrier performance.

Related standards

ISO 9073 is a multi-part series (test methods for nonwovens) — related parts include ISO 9073-1 through ISO 9073-18 covering mass per unit area, thickness, tensile and tear, absorption, liquid strike-through, air permeability and other properties. Other referenced standards commonly used with ISO 9073-16 include standards for conditioning and test atmosphere and water quality (for example, ISO conditioning standards and water purity references noted in the normative references of ISO 9073-16).

FAQ

Q: What is this standard?

A: ISO 9073-16:2007 is Part 16 of the ISO 9073 series of test methods for nonwovens; it specifies a hydrostatic pressure test to determine the resistance of nonwoven fabrics to penetration by water.

Q: What does it cover?

A: It covers the principle, apparatus, specimen preparation, test procedure (pressure application and endpoint determination), reporting and related requirements to measure the hydrostatic head at which water first penetrates a nonwoven specimen. The method is aimed at nonwovens used as fluid barriers.

Q: Who typically uses it?

A: Manufacturers of nonwoven materials, product development and QA laboratories, third‑party testing houses, specifiers and certification bodies that need standardized, comparable measurements of water penetration resistance.

Q: Is it current or superseded?

A: ISO 9073-16:2007 is the first edition published in December 2007. The ISO bibliographic record shows the standard was reviewed and confirmed (no superseding edition) in subsequent systematic reviews (including confirmation in 2011, 2016 and 2021), so the 2007 edition remains the current published version and was confirmed as current at the last ISO review. Users should check ISO or national standards bodies for any newer amendments or replacements beyond the last confirmation.

Q: Is it part of a series?

A: Yes — ISO 9073 is a multi‑part series of test methods for nonwovens (Parts 1–18 cover mass, thickness, tensile and tear, absorption, strike‑through, air permeability, water penetration by spray impact, etc.). ISO 9073-16 is the part that specifically addresses hydrostatic pressure water penetration testing.

Q: What are the key keywords?

A: Nonwovens, hydrostatic pressure, water penetration, hydrostatic head, barrier, textile test, ISO 9073-16, water resistance.
