ASTM D1998 & AS/NZS:4766 Оба требуют :
Долгосрочные физические свойства
Наклонение конструкции Hoop (HDS) в соответствии с ASTM2837
Краткосрочные физические свойства обычно предоставляются
большинством поставщиков полимеров
ASTM D1998 & AS/NZS4766 tank standards both require :
Long Term Physical Properties
Hoop Design Stress (HDS) according to ASTM2837
Short term physical properties (Tensile & Flexural) are provided by most
polymer suppliers

PlasticDeformation
Когда дается нагрузка или напряжение, ниже критического уровня,
полимер реагирует на нагрузку, деформируя
какую то часть себя, а когда нагрузка ослабевает, полимер снова
возвращается в первоначальную форму.
When the load is released, the polymer relaxes back into its original shape.
When a load or stress is applied, below a critical value, the polymer can respond to the
load by deforming a certain amount, and when the load is released, the polymer
relaxes back into its original shape.

Stressversustime
Полимеры могут справляться с высоким напряжением, в течении
коротких периодов времени, или же с низким напряжением, в
течении длительных периодов времени. Но когда нагрузка
дается выше критического значения, полимер в конечном итоге
терпит неудачу (ломается).
Polymers can cope with high stress for
short periods of time,
or Polymers can cope with low stress for
long periods of time.
When a load is applied above a critical
value the polymer will ultimately fail
(fracture).

Designwithconfidence
Design your tank using recognised standards (ie. ASTM D1998 or
AS/NZS:4766) to avoid possible failure of your tank.
Understand the difference between short term performance
(Tensile & Flexural) and long term performance (Hydrostatic
Design Stress & Creep).
Globally recognised tank standards require long term
performance data.
Request both short term and long term physical properties for
the polymer you intend to use.
