What are the standard pressure ratings for these agricultural pipes?

The standard specifies pressure classes of 4, 6, 8, and 10 kgf/cm² (Clause 5.3).

What is the maximum reversion allowed for these pipes?

The longitudinal reversion must not exceed 5% when tested according to IS 12235 (Part 5) (Table 2).

Can IS 10124 pipes be used for drinking water supply?

No, this standard is for agricultural pump sets. Pipes for potable water supply are covered by IS 4985.

What is the minimum Vicat softening temperature?

The minimum Vicat softening temperature should be 76°C when tested as per IS 6307 (Table 2).

Practical Notes

These pipes are specifically designated as 'Agri' pipes and should not be confused with or substituted for potable water pipes under IS 4985.

The standard covers both plain-ended suction pipes and delivery pipes which may have an integral socket.

Ensure proper storage away from direct sunlight to prevent UV degradation and brittleness.
