Summary of Practice4.1 This practice defines test methods and procedures forevaluating the resistance of geonet to liquid exposure bymonitoring physical and ch
17、emical properties of geonet speci-mens immersed in a test liquid. The physical condition of thegeonet is monitored as a function of cumulative exposure timeby means of dimensional measurements and physical andchemical property tests.5. Significance and Use5.1 This practice is intended to provide a l
18、ist of standardprocedures for test programs for investigating the chemicalresistance of a geonet with a liquid waste, leachate, orchemical. This practice should be used in the absence of otherspecifications required for the particular situation being ad-dressed.5.2 Chemical resistance, as used in th
19、is practice, is not aquantifiable term. This practice is intended to provide a basis ofstandardization for those wishing to compare or investigate thechemical resistance of a geonet. It should be recognized thatchemical resistance is a user judgment evaluation and that thispractice does not offer pr
20、ocedures for interpreting the resultsobtained from test procedures contained herein. As a practice,a test result is not produced.5.3 This practice is for the chemical resistance assessmentof geonets and is written in parallel to similar practices forgeomembranes, geogrids, geotextiles, and geopipes.
21、 Each prac-tice is to be considered individually for the geosynthetic underinvestigation and collectively for all geosynthetics exposed tothe potentially harsh chemical environment under consider-ation.6. Apparatus6.1 Analytical Balance, capable of weighing to an accuracyof 0.001 g.6.2 Measuring Equ
22、ipment, such as scales or calipers, suit-able for determining dimensions of geonet specimens.6.3 All other required equipment is specified in the refer-enced test methods. Refer to the appropriate standards for adescription of the apparatus necessary to perform those tests.7. HazardsNOTE 1Warning: T
23、he solutions used in this practice may containhazardous chemicals. Appropriate precautions must be taken when han-dling hazardous waste, chemicals, and the immersion solutions. Protectiveequipment suitable for the chemicals being used must be worn by allpersonnel handling or exposed to the chemicals
24、. Particular care should betaken when opening storage vessels at elevated temperatures due to theincreased volatility of organics and the increased activity of acids andbases. Care also must be taken to prevent the spilling of hazardousmaterials, and provisions must be made to clean up any accidenta
