ISO 23409:2011

Overview

ISO 23409:2011 - "Male condoms - Requirements and test methods for condoms made from synthetic materials" - specifies minimum requirements and test methods for male condoms manufactured from synthetic materials or blends of synthetic materials and natural rubber latex. The standard covers design, preclinical and clinical evaluation, lot-by-lot quality verification, physical performance (bursting, holes, dimensions), biocompatibility, packaging integrity, labelling and shelf-life. It is intended to ensure condoms function effectively for contraception and in helping to prevent sexually transmitted infections (STIs).

Key topics and technical requirements

• Scope and definitions: Clarifies terms such as lot, individual container, expiry date, visible/non-visible holes, shelf-life.
• Design and product claims: Requirements for fit, retention, strength and barrier validation to infectious agents and spermatozoa.
• Preclinical and clinical evaluation: Guidance on laboratory testing and clinical investigations to demonstrate safety and effectiveness before routine lot testing.
• Physical performance tests:
  • Bursting volume and pressure testing (annexes describe methods).
  • Freedom from holes (water/electrical/bacteriophage methods referenced in annexes).
  • Dimensions and thickness measurements (length, width, thickness).
• Biocompatibility: Evaluation of materials and additives to avoid toxicity, sensitization or irritation (referenced ISO 10993 series).
• Sampling and lot release: Lot-by-lot sampling plans and inspection schemes (Annex A/B; ISO 2859-1) for ongoing quality verification.
• Stability and shelf-life: Real-time stability tests, accelerated ageing guidance and determination of expiry date.
• Packaging and labelling: Individual container integrity tests, consumer package labelling and traceability requirements.
• Documentation: Required data sheets and test reports for regulatory compliance and traceability.

Practical applications

• Manufacturer quality systems: design controls, production validation and routine lot release testing.
• Regulatory submissions: evidence for safety, performance and shelf-life in conformity assessments.
• Test laboratories: standardized methods for burst, hole, dimensional, lubricant and packaging integrity testing.
• Procurement and public health programs: product selection criteria and supplier audits for condoms used in family planning and STI prevention.
