The results of these experiments have been considered by the Joint Committee for the Co-ordination of the Cathodic Protection of Buried Structures and, in view of the various types of buried structures concerned and the circumstances in which field tests are conducted, the Committee decided not to amend its provisional recommendation that when cathodic protection is applied to a buried structure the maximum permissible potential change in the positive direction on a nearby pipe or cable should be 20 mV. If there is a history of corrosion on the unprotected installation no detectable positive change in structure/soil potential should be permitted. These criteria of interaction have been adopted in the British Standard Code of Practice for Cathodic Protection .

There are several British Standards that deal with liquid pyknometry applied to specific materials12-13-141516. A pyknometer bottle of up to 50 ml volume is usually sufficient for fine powders but coarse materials may require larger calibrated vessels. BS 1377 1975, for example, requires the use of a 1 litre cylindrical gas jar, closed by a ground plate, to measure the density of soils that contain particles coarser than 2 mm BS test sieve (but not coarser than 37.5 mm). 

British Standard for soils, for example16, defines a liquid limit at which a soil passes from the plastic to the liquid state and determines it by the liquid limit test. The test consists of preparing a sample of wet soil and pushing it into a test cup. A cone... 

Note that a portable tester based on the same principle as the compression tackiness tester is defined by a British Standard for testing of soils16. It uses a split mould 38 mm in diameter and 76 mm long (note the 2 1 ratio), with the sample of soil extruded into it from a sampling tube. The load is applied manually by a rotary handle and a lead screw, through a calibrated spring. 

Sometimes the density of powder compacted over and above what can be achieved by tapping may be needed. There are no standard procedures for this other than the rather specialized soil compaction tests and density determinations (2.5 and 4.5 kg rammer methods) quoted in a British Standard for soils16.

According to British Standard (PAS 100) compost means solid particirlate materials that are the result of composting, that have been sanitized and stabilized and that eorrfer beneficial effects when added to soil and/or ttsed in conjtmction with plarrts. 

See for example, British Standard 1377, 1948, Methods of Test for Soil Classification and Compaction (this standard was revised in 1961).
