IS 17899 T : 2024 Assessment of Biodegradability of Plastics in Varied Conditions (Tentative Indian Standard)
1 SCOPE
1.1 This tentative Indian Standard specifies theprocedures and assessment of biodegradability ofplastics under varied conditions. This standardaddresses the following aspects:
a) Biodegradation in varied conditions, asspecified;
b) Analysis of effects of resulting biomass onterrestrial plant growth/organism; and
c) Negative effects of the quality of theresulting biomass including the presence ofhigh levels of regulated heavy metals.
1.2 The standard is applicable for assessing thebiodegradability of plastics under aerobic,anaerobic conditions.
1.3 The standard is not applicable for assessingthe biodegradability of plastics under marineenvironment.
1.4 The assessment of biodegradability of plastic, ifdone through composting conditions only, videIS/ISO 14855-1 and IS/ISO 14855-2, the plastic shallbe certified as compostable plastic, and not asbiodegradable plastic as defined under PWM Rules,2016, as amended.
1.5 This standard excludes compostable plastics asper IS/ISO 17088, as per PWM Rules, 2016, asamended.
