	Grading of material (% of each particle size) Percentages of clay and silt fractions* [ * if pipette analysis performed]	Specify if pipette analysis is required to individually determine clay and silt content If pipette analysis is specified, what quantity of fine material (passing 63µm sieve, clay and silt) needs to be present to require the pipette analysis to be performed (eg. only if >10% fines present)
	Typical use(s):	Material required:
	Basic classification of material according to its particle size.	Depends on particle size. For not more than 10% of the following sizes, use the corresponding sample mass
		63mm	50 kg
		50mm	35 kg
		37.5mm	15 kg
		28mm	6 kg
		20mm	2 kg
		14mm	1 kg
		10mm	500 g
		6.3mm	200 g
		3.35mm	150 g
		< 2mm	100 g
	Description	Price excl. VAT
	Particle size distribution by Wet sieve analysis (BS1377 : Part 2 : Clause 9.2 : 1990)	£ 27.50
	Particle size distribution by Dry sieve analysis (BS1377 : Part 2 : Clause 9.3 : 1990)	£22.50 NOTE: This test is for non-cohesive material only. Cohesive material will need to be wet sieved.
	Mechanical analysis by Pipette method (BS1377 : Part 2 : Clause 9.4 : 1990)	£ 27.50 NOTE: This price is in addition to a sieve analysis test (see note below for fine-grained materials)
	BOTH Particle size distribution by Wet sieve analysis (BS1377 : Part 2 : Clause 9.2:1990) AND Mechanical analysis by Pipette method (BS1377 : Part 2 : Clause 9.4 : 1990) ON THE SAMPLE SAMPLE WHERE ALL MATERIAL IS SMALLER THAN 2mm	£ 42.50 NOTE This price is for fine-grained material only (i.e. only for clay, silt and sand - NO gravel). If any of the material is larger than 2mm, add the individual wet sieve and pipette test prices together: £ 27.50 + £ 27.50 = £ 55.00
