Standard
ISO 14782 Plastics – Determination of haze for transparent material
ISO 14782 specifies a method for measuring haze — an optical property arising from wide‑angle scattering of light — in transparent and substantially colourless plastics. Quantifies haze (wide-angle light scattering) of flat, substantially colourless transparent plastics, with a valid measurement range of haze below 40%.
ASTM D1003 Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics
ASTM D1003 covers the evaluation of specific light-transmitting and wide-angle-light-scattering properties of planar sections of materials such as essentially transparent plastic. It defines how to quantify two key optical properties of planar, essentially transparent plastic sheets or films.
ASTM D1044 Standard Test Method for Resistance of Transparent Plastics to Surface Abrasion
ASTM D1044 test methods for transparent plastics, designed to quantify surface scratch/wear damage via optical haze change instead of mass or volume loss (volume loss measurement is abandoned due to poor inter-laboratory repeatability). The core evaluation indicator is haze difference (Δhaze) between unabraded and abraded samples.
ISO 13468-1 Plastics – Determination of the total luminous transmittance of transparent materials – Part 1: Single-beam instrument
ISO 13468-1 specifies a method for measuring total luminous transmittance (τₜ) in the visible region of planar, transparent and substantially colourless plastics, using a single‑beam photometer with a specified CIE standard light source and photodetector. Application for planar, nearly colourless transparent plastic films, sheets and moulded parts ≤10 mm thick; faintly tinted plastics are permitted.
ISO 17555 applies to packaging-grade BOPP films containing ≥95% polypropylene resin; usable as single-layer film or laminates paired with other plastic substrates. The test stipulated in ISO 17555 mainly include, tensile strength & strain at break, Dimensional change on heating (thermal shrinkage), Coefficient of water vapour transmission, Haze, Wetting tension etc.,
ISO 15988 specifies requirements for biaxially oriented transparent PET (BOPET) films, mainly used for packaging, either alone or as a laminated layer with other films. The main test stipualted in this standard include tensile strength and strain, Dimensional change on heating, Oxygen transmission coefficient, Water vapour transmission coefficient, Haze, Wetting tension, thickness etc.,
ISO 15987 specifies classification, mandatory visual, dimensional, mechanical, barrier, optical, surface energy, and food contact safety requirements for transparent BOPA film, supplied in roll form, either used standalone or laminated with PE, CPP, PET, aluminium foil for multi-layer packaging structures. The test stipulated in ISO 15987 mainly include, tensile strength & tensile strain at break, Oxygen transmission coefficient, Dimensional change on heating, Haze, Wetting tension etc.,
