ISO 1419:2019

Overview

ISO 1419:2019 - Rubber- or plastics-coated fabrics - Accelerated-ageing tests - defines four accelerated-ageing methods to assess how coated fabrics deteriorate under controlled heat, humidity and time. The standard is primarily used to evaluate loss of volatiles (plasticizer loss in plasticized-PVC), general heat ageing, tropical high-humidity ageing, and specific ageing for nitrocellulose-type coatings. It references ISO 188, ISO 2231 and ISO 2286 series for procedures, conditioning and mass determinations.

Key topics and technical requirements

• Four test methods (A–D):
  • Method A - Loss of volatiles on heating (for plasticized PVC): measures mass loss after exposure at 100 °C and reports loss as a percentage of coating mass. Uses ISO 188 procedures.
  • Method B - General elevated-temperature ageing: exposes specimens to warm air (typically 70 °C) and evaluates post‑exposure physical/chemical changes.
  • Method C - Tropical test: high‑humidity accelerated ageing (relative humidity not less than 95 %) to simulate tropical environments.
  • Method D - Specific ageing for nitrocellulose-type coatings.
• Apparatus and environmental control:
  • Air oven with slow air circulation (3–10 air changes per hour), temperature control (e.g., 100 °C ±1 °C for Method A, 70 °C ±1 °C for Method B), accurate thermometry and capability to suspend specimens without contact or direct radiant heating.
  • Restrictions inside the oven (no copper/copper alloy, specimen spacing and oven free air-space limits).
• Specimen preparation and measurement:
  • Defined numbers and placement of test pieces (e.g., Method A calls for multiple specimens, avoiding selvedges).
  • Conditioning atmospheres per ISO 2231 and mass determinations per ISO 2286-1/2.
  • Balance accuracy requirements (e.g., 1 mg for Method A).
• Reporting:
  • Required test report content includes method reference, fabric identification, conditioning atmosphere, individual and mean results, and any deviations.

Applications and users

• Who uses ISO 1419:2019:
  • Manufacturers of rubber- or plastics-coated fabrics (PVC‑coated, nitrocellulose coatings, etc.)
  • Independent test laboratories and QA/QC teams
  • Product designers, materials engineers and failure‑analysis specialists
  • Procurement and compliance officers specifying durability requirements
• Practical uses:
  • Quality control and batch verification to detect plasticizer loss or other ageing-related changes
  • Comparative evaluation of coating formulations and substrates
  • Simulating service environments (hot, humid, tropical) for product development
  • Supporting specifications, claims and conformity assessments for coated textile products

Related standards

• ISO 188 - Rubber - Accelerated ageing and heat resistance tests
• ISO 2231 - Standard atmospheres for conditioning and testing (conditioning atmospheres A, B, C)
• ISO 2286-1 / ISO 2286-2 - Determination of roll characteristics; coating and substrate mass per unit area

ISO 1419:2019 is essential when you need standardized, reproducible accelerated‑ageing data for coated fabrics used in outdoor, industrial or tropical applications.
