(Test Method)Standard Test Method for Particle Size Analysis and Sand Shape Grading of Golf Course Putting Green and Sports Field Rootzone Mixes
Standard Test Method for Particle Size Analysis and Sand Shape Grading of Golf Course Putting Green and Sports Field Rootzone Mixes
ABSTRACT
These test methods establish the apparatus required, standard procedures, and associated calculations for determining the particle size distribution and shape grading of sand in golf course putting green and other sand-based sports field rootzone mixtures assumed to have sand contents of 80 % by weight or greater. Particles large enough to be retained on a No. 270 sieve are determined by sieving, while, the silt and clay percentages are determined by a sedimentation process using the pipet method.
SCOPE
1.1 This test method covers the determination of particle size distribution of putting green and other sand-based rootzone mixes. Particles larger than 0.05 mm (retained on a No. 270 sieve) are determined by sieving. The silt and clay percentages are determined by a sedimentation process, using the pipet method. This procedure was developed for putting green rootzone mixes, those assumed to have sand contents of 80 % by weight or greater. Particle size analysis of soils may be performed by this test method or Test Method D 422. This test method also describes a qualitative evaluation of sand particle shape.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
