Foreword
This standard is GB/T 12746-1991 "standard penetrometer" amendments.
The main difference compared with the standard GB/T 12746-1991 as follows.
--- Increased emphasis penetrometer and pocket penetrometer technical content;
--- Increased penetrometer environment, storage environmental requirements;
--- Increase the working environment requirements and material requirements;
--- Complements the inspection rules and signs, packaging, transportation and storage requirements;
--- On the provisions of the relevant contents of the original provisions and adjustments were made to broaden appropriate, and be clarified;
--- The technical contents of this standard, related primarily to product design, manufacturing, testing and test related product standards, technical
Select the application preparation conditions.

3 Terms and Definitions
GB/T 50279 and established the following terms and definitions apply to this standard.
3.1
The kinetic energy of the hammer to a predetermined standard of penetration is hit into the soil at the bottom of the borehole to a predetermined depth, and measuring and recording the corresponding standard
In situ geotechnical penetrometer test equipment hit numbers.
3.2
By the partial probe, measuring devices, reading devices and other components, estimate soil bearing capacity, rapid assessment portable test instrument soil bearing capacity.
3.3
Quality mandrel hammer heavier, off a high increase in the penetration of the outer diameter of the enlarged penetrometer.
3.4
Standard penetrometer, increased penetrometer assembled by the penetration device boots, waffle cones, penetration head, drain holes and other devices from the penetration side
In contact with the soil type, carrying its penetration resistance of rigid metal utensils.
3.5
Pocket penetrometer rigid metal body having a predetermined shape and size and direct way to CPT soil contact.
