[k.sub.p] C where H and [H.sup.O] represent the crushing strengths
of the batches made with the given excipient and the control tablets batch, respectively.
The crushing strength-friability ratio ([C.sub.t]/[F.sub.t]) is a better measure of the mechanical strength of tablets than crushing strength
as it removes the weakness related to the friability of a tablet .
Two important indicative properties of brick and brick aggregate are crushing strength
of brick and water absorption of brick aggregate.
Table 2: Crushing Strength
(CS) Friability (FR) and CSFR/D Values for Paracetamol Tablet Formulations
of 10 randomly selected tablets was determined using a hardness tester (DBK Instruments, India).
were tested for cold crushing strength
, spalling resistance and permanent linear change on reheating.
Most current methodology relies on indirect measurements such as tablet crushing strength
and friability to assess tablet robustness and coating weight gain to estimate the amount of coating on tablets.
Samples of southern yellow pine outer bark and wood were tested in compression to determine values for modulus of elasticity, stress at proportional limit, and maximum crushing strength
. Results reported here resolve inconsistencies in the compressive strength data previously reported by others for pine bark.
Each entry provides thorough information on appearance, growth rate, distribution (with maps), working properties (in both narrative and chart form: impact resistance, stiffness, density, workability, bending strength, and crushing strength
), and commercial uses, both historical and current.
Both underwent eight cycles of [S.sub.0] recurrent selection for high stalk crushing strength
The weight-bearing capacity of the Florida Mat Rental system is not as dependent on the crushing strength
of the wood as it is on the weight-bearing strength of the soil system below.
Methods of testing clay pipe for crushing strength
, absorption; and acid resistance are outlined in ASTM C301, "Standard Method of Testing Vitrified Clay Pipe." ASTM C828 is a recommended practice for "Low-Pressure Air Test of Vitrified Clay Pipe Sewer Lines (4 through 12 in.)." In the recommended procedure, a section of line is plugged and air is introduced into the line.
