This European Standard specifies a test method for the determination of the resistance of protective
clothing, gloves and footwear materials to permeation by potentially hazardous gaseous chemicals
under the condition of continuous contact.
This test method is applicable to the assessment of protection against gazeous chemicals that can be
collected only by liquid or gaseous collecting media.
!This test method is not applicable for the assessment of gaseous chemical mixtures."
This test method describes the modifications to EN 16523-1 necessary to test against gaseous chemicals
that can be collected by liquid or gaseous collecting media.

Diese Europäische Norm legt ein Prüfverfahren für die Bestimmung des Widerstands von Schutzkleidungsmaterial, Schutzhandschuh- und Fußschutzmaterial gegen die Permeation von potentiell gefährlichen gasförmigen chemischen Stoffen unter Dauerkontakt fest.
Dieses Prüfverfahren gilt für die Beurteilung des Schutzes gegen gasförmige chemische Stoffe, die nur mit flüssigen oder gasförmigen Sammelmedien erfasst werden können.
!Dieses Prüfverfahren ist nicht für die Beurteilung gasförmiger chemischer Gemische anwendbar."
Dieses Prüfverfahren beschreibt die erforderlichen Änderungen der EN 16523 1, um gasförmige chemische Stoffe zu prüfen, die mit flüssigen oder gasförmigen Sammelmedien erfasst werden können.

Ta preskusna metoda se uporablja za vrednotenje zaščite pred plinastimi kemikalijami, ki jih je mogoče zbrati samo s tekočimi ali plinskimi mediji za zbiranje.
»Ta preskusna metoda se ne uporablja za ocenjevanje plinastih kemičnih zmesi.«
Ta preskusna metoda opisuje spremembe standarda EN 16523-1, ki so potrebne za preskušanje plinastih kemikalij, ki jih je mogoče zbrati s tekočimi ali plinskimi mediji za zbiranje.

Overview

EN 16523-2:2015+A1:2018 is a CEN European Standard that specifies a laboratory test method for determining material resistance to permeation by potentially hazardous gaseous chemicals under conditions of continuous contact. It is part of the EN 16523 series and complements EN 16523-1 (liquid challenge chemicals) by describing the specific apparatus, procedures and detection techniques needed for gaseous challenge chemicals. The standard covers single gaseous chemicals (pure or diluted in air or nitrogen) and is not applicable to gaseous mixtures.

Key topics and technical requirements

• Test principle: Permeation is quantified by measuring the normalized breakthrough time (NBT) and permeation rate of the chemical through a PPE material as a function of time.
• Scope of materials: Applies to protective clothing, gloves and footwear materials tested under continuous contact.
• Apparatus and setup:
  • Modified permeation cell design to accommodate a gaseous challenge chamber and collecting medium (gas or liquid).
  • Challenge gas introduced at a pressure just above ambient to achieve an initial flow of (5 ± 0.5) cell volumes per minute without deforming the specimen.
  • Temperature control: nominal test temperature (23 ± 1) °C; other temperatures may be used if relevant.
• Collecting media: Selection depends on oxidation, solubility, hydrolysis and compatibility with detection methods; collecting media can be gaseous or liquid.
• Sampling and detection:
  • The concentration in the collecting medium is measured periodically or continuously to define breakthrough. Minimum sampling frequencies are specified depending on expected test duration (table-based guidance up to and beyond 8 h).
  • Annex A provides examples of detection techniques for common gases (FTIR, PID, FID, electrochemical detectors, GC-MS, etc.).
• Procedure and results:
  • Calibration, specimen preparation and calculation/reporting follow EN 16523-1 with the adjustments in this part.
  • Nominal test duration is 8 hours unless otherwise specified; three specimens are tested and visual changes recorded.
• Limitations: Not intended for gaseous chemical mixtures.

Applications

• Assessing resistance of PPE materials to hazardous gases for occupational health and industrial hygiene.
• Laboratory testing by third‑party test houses and manufacturers to support product selection, CE marking and safety data.
• Risk assessment and specification of protective clothing, gloves and chemical protective footwear used in chemical processing, emergency response, laboratories, agriculture and other industries with gas hazards.

Who will use this standard

• PPE manufacturers and material suppliers
• Accredited testing laboratories and certification bodies
• Safety engineers, EHS officers and procurement teams specifying chemical protective equipment
• Regulators and conformity assessment bodies

Related standards

• EN 16523-1 (Permeation by liquid chemicals)
• EN 374 series (protective gloves vs chemicals and micro‑organisms)
• EN 13832 series (chemical protective footwear)
