1. SCOPE

1.1 This standard prescribes the requirements and methods of sampling and tests for polyethylene mulch films for agriculture and horticulture purpose.

1.2 The polyethylene mulch films of thickness below 30 microns have not been considered because retrieval of film from the field is not possible because of degradation of the film when in use.

NOTE - This standard does not cover compostable polyethylene mulch films.
