Overview

EN 13206:2017/prA1 (CEN draft amendment A1, 2018) is a European standard for plastics - thermoplastic covering films for use in agriculture and horticulture. It specifies performance classes, exposure and test methods, and labelling/management information for greenhouse and horticultural films. The 2018 amendment updates normative references, artificial weathering classification, test procedures and calibration requirements to improve reproducibility and link test results to real-life durability.

Key topics and technical requirements

• Scope: Thermoplastic covering films used in greenhouses and horticultural installations (weathering, mechanical and chemical properties).
• Weathering classification: Revised Table 2 sets minimum artificial exposure durations for durability classes (N to F) at two irradiance levels (narrowband 340 nm: 0.35 and 0.51 W/(m·nm)), with an informative correlation to natural exposure.
• Artificial weathering / light exposure: Adds EN ISO 4892-1 as a normative reference and tightens apparatus temperature control and calibration requirements.
  • Temperature set points specified by apparatus type (examples: (60 ±0.5) °C, (65/55 ±0.5) °C, (58 ±0.5) °C) and requirement for calibration against photochemical response.
  • Calibration via polyethylene reference specimens (PERS) per ISO/TR 19032 for photochemistry-relevant calibration.
• Mechanical testing: After exposure, tensile strain-at-break determined per EN ISO 527-1/527-3 using five Type 2 specimens (10 mm × 150 mm) cut longitudinally, test speed 500 mm/min.
• Chemical composition tests:
  • Chlorine: Determined by oxidative pyrolysis with coulometry; if UV absorbers such as benzotriazole are present, their non-reactive chlorine must be quantified and subtracted.
  • Sulfur: Determination using ICP-OES (inductively coupled plasma optical emission spectrometry).
• End-of-life and recycling: References to standards for plastic waste characterization and recyclate data (EN 15347, EN 15343, EN 15344) and ISO 15270 guidance for recovery/recycling.

Applications and who should use it

• Manufacturers of greenhouse and horticultural films - for product development, quality control and durability classification.
• Testing laboratories - for standardized artificial weathering, tensile and chemical analyses and apparatus calibration.
• Growers, agronomists and greenhouse designers - to select films with appropriate durability and chemical/optical properties.
• Procurement/specifiers and regulators - to define performance requirements and compliance criteria in tenders and certifications.
• Recyclers and waste managers - for guidance on end-of-life characterization and traceability of polyethylene recyclates.

Related standards (selected)

• EN ISO 4892-1 - Methods of exposure to laboratory light sources (general guidance)
• EN ISO 527-1 / EN ISO 527-3 - Tensile properties of plastics
• ISO/TR 19032 - Use of polyethylene reference specimens (PERS)
• ISO 15270 - Guidelines for recovery/recycling of plastics waste
• EN 15343 / EN 15344 / EN 15347 - Recycled plastics traceability and characterization
