This protocol has been developed to address polypropylene (PP)@ polyethylene (PE or HDPE)@ and polyester (PET) geosynthetics (i.e.@ geotextiles and geogrids). For other geosynthetic polymers [(e.g.@ polyamide (PA) or polyvinyl alcohol (PVA)]@ the installation damage and creep protocols provided herein are directly applicable. While the chemical and biological durability procedures and criteria provided herein may also be applicable to other polymers (for example@ hydrolysis testing as described in Annex C is likely applicable to PA and PVA geosynthetics)@ additional investigation will be required to establish a detailed protocol and acceptance criteria for these other polymers. These other polymers may be considered for evaluation using this protocol once modifications to the chemicalhiological durability aspects of this protocol have been developed and are agreed upon by the approval authority This standard may involve hazardous materials@ operations@ and equipment. This standard does not propose to address all safety problems associated with its usage. It is the duty and responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1-The values stated in SI units are to be regarded as the standard.
