Overview
EN ISO 11721-1:2001 - Textiles: Determination of the resistance of cellulose-containing textiles to micro-organisms - Soil burial test (Part 1: Assessment of rot-retardant finishing) - is a CEN-adopted method that specifies how to evaluate the effectiveness of rot-retardant (imputrescible) finishes on cellulosic textiles when exposed to micro-organisms present in soil. The standard defines a comparative test procedure for chemically pretreated (finished) textiles against untreated controls, focusing on products that typically contact soil during use.
Key topics and requirements
- Scope and applicability
- Applicable to flat textiles made from cellulose-containing yarns (examples: tentage, tarpaulins, webbing, tapes).
- Designed to assess resistance to micro-organisms in soil for chemically pretreated textiles.
- Comparative assessment
- Requires comparison between treated (rot-retardant finished) samples and untreated counterparts to determine treatment effectiveness.
- Limitations
- Acknowledges that synthetic fibres are inherently more resistant to microbial attack; where fabrics contain a high proportion of synthetics, this method is limited to assessing changes in structure and appearance rather than biological degradation.
- Test focus
- Concentrates on the soil burial test methodology - a practical simulation of real-world soil exposure to evaluate rot resistance and durability of finishing.
Applications
- Performance evaluation of rot-retardant finishes applied to cellulose-containing textiles intended for outdoor or ground-contact use (e.g., tents, tarpaulins, ropes, slings).
- Routine quality control and acceptance testing for textile manufacturers and finishers to validate preservative treatments.
- Product development and comparative studies when selecting finishing chemistries for enhanced microbial resistance.
- Compliance checks for procurement of durable textiles used by military, camping/outdoor equipment manufacturers, civil engineering, and industrial safety sectors.
Who should use this standard
- Textile manufacturers and finishers working with cellulosic fabrics
- Independent and in-house textile testing laboratories
- Product development teams and quality assurance professionals in the outdoor, industrial and technical textile sectors
- Procurement specialists and certification bodies requiring standardized evaluation of rot resistance
