Strength of pipes The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack.

Asbestos-cement pipe is covered by three nationally recognized stand-ards.13 AWWA Committee 8340 D-Asbestos-Cement Pipe, was formed in 1949, and its first standard issued in 1953. This standard * covers the gen-eral design and required strength char-acteristics of asbestos-cement pipe. The following description should
Fiberglass pipe sections were tested per ASTM D6382 and ASTM D2290 Procedure A3to determine axial and hoop tensile strength respectively. Additionally, a transverse cross section of the pipe wall was mounted, polished, and examined using an optical microscope. The asbestos cement pipe section was crush tested per ASTM C5004 crushing strength test.

Asbestos cement building pipes are used extensivelv as rain-water pipes, soil and waste pipes anti ventilating pipes. The lightness 01 asbestos cement pipes and their durability make them suitable for all normal building purposes. This standard was first published in 1960 and subsequently revised in 1980.

2.3 Factors Influencing Deterioration of Asbestos Cement Pipes Asbestos cement pipe production ceased in 1986 in New Zealand and Australia. Most pipes have now been in service for at least 30 years with the oldest confirmed NZ pipes in service for almost 80 years.
NOTE 1 In a pipe work system, pipes and fittings of different strength classification can be used together. NOTE 2 Piping systems conforming to this International Standard can be used also for non-buried applications provided the influences of the environment and the supports are considered in the design of the pipes, fittings and joints.
Approved materials for a building sewer include clay tile, asbestos-cement sewer pipe, and plastic sewer pipe with lettering indicating 1,000 pound crush test, and that it meets the specifications of either Commercial Standard 22861 or ASTM D2751- 68. In addition, any material approved for the underground drainage system -
The widespread use of asbestos cement pipes in distribution systems has raised concerns that the fibres found in water may be a danger to health. A study carried out in the UK found that some drinking waters can contain up to 1 million asbestos fibres per litre, with more than 95% of these being less than 2 m in length (WRc, 1984).

These testing methods use phase contrast light microscopy and transmission electron microscopy to accurately measure the presence of asbestos fibers in air samples to a detection limit of 0.1 fibers per cubic centimeter of air or an asbestos fiber that is 5 micrometers long (NIOSH Manual of Analytical Methods, 1994).
Asbestos is stronger than steel and its thermal coefficient matches with cement. It provides a homogenous, microscopic, three dimensional reinforcement in AC. Thus, it can withstand more than 15 times the water pressure than a concrete pipe of similar thickness. Has a durability of about 100 years gains strength with age

Asbestos-cement pipe shall be designated as Class II or Class III based on the crushing strength per foot of pipe as listed in the following table Crushing D Load
Pipes are generally defined as rigid when they are likely to fracture under small deformations, so this often includes asbestos-cement pipes and grey cast iron pipes as well as concrete and clay. In reality the definition is always a judgement as the flexibility of the system will vary based on pipe material, pipe diameter and bedding material.
