Laboratory
Laboratory Services Include:
- Collaboration laboratory of the National Standards Organization of Iran for testing all light/heavy vehicle air filters based on National Standard 34.
- Complete testing of air filters for light vehicles according to Iran's National Standard 34
Section 3-6 of Iran's National Standard 34
- -Testing of airflow restriction and pressure differential
- Efficiency testing
- Capacity testing
- Disintegration testing
- Temperature cycle testing
The purpose of this test is to determine the restriction/pressure differential of the unit under test when air passes through it under predetermined conditions. The airflow restriction or pressure differential is measured with a clean filter element or filter elements at five equal increments of airflow between 50% and 150% of the nominal airflow, or as agreed upon by the manufacturer and user.
Section 3-6 of Iran's National Standard 34
The purpose of this test is to determine the impurity retention capability of the unit under test. This test can be conducted with either a constant or variable airflow and with fine or coarse dust. If desired, efficiency and capacity tests can be performed simultaneously
Section 4-6 of Iran's National Standard 34
The purpose of this test is to determine the total mass obtained from the unit under test in final conditions. This test can be conducted with either a constant or variable airflow and with fine or coarse dust. If desired, capacity and efficiency tests can be performed simultaneously.
Section 5-6 of Iran's National Standard 34
The purpose of this test is to determine the capability of the air filter element in terms of resistance to a specified pressure differential, or to determine the pressure differential at which the disintegration of the air filter element occurs.
Section 6-6 of Iran's National Standard 34
The purpose of this test is to determine the performance of the air filter in relation to high and low temperatures. To conduct this test, the air filter element is placed between two heat-resistant plates and secured with a specified torque. The assembly is then exposed to a predetermined cycle of warm and cold air. At the end of the test, no mechanical failure or evaporation of the adhesive between the paper folds is permitted.
