UN Certifications
When and Why do we need UN Certifications?
UN Certifications are required for packaging, marking and labelling of dangerous goods, in order to transport it safely (by road, rail, sea and air). Testing is required to be carried out before a UN Certification can be issued.
Are UN Certifications valid internationally?
Yes, they are valid internationally
Which test are mandatory for UN certifications
Depending on the material and type of Drum, Drop test, Stack test, Cobb test, Leakproofness test and Hydraulic test may be required.
Are Single certificate valid for Air and Sea?
Single certificates are valid for air and sea transportation.
What is Packing Group?
The Packing Group is a grouping of substances (other than those in Hazard Class 2, Class 6 Division 2, and Class 7), in accordance with the degree of danger they present: The appropriate packaging is also dependent on the Packing Group of the material
- Packing group I(X): substances presenting high danger;
- Packing group II(Y): substances presenting medium danger; and
- Packing group III(Z): substances presenting low danger.
Biodegradation
What is Biodegradility Testing?
Biodegradability testing measures the complex biochemical process that occurs when microorganisms consume a given type of material. Although complicated, the test results measure relatively simple markers of the biodegradation process.
How to check Biodegradability of plastics?
You can check Biodegradability of plastics by testing the products as per ASTM D or ISO test methods
What is Aerobic Biodegradation?
Aerobic Biodegradation is the breakdown of organic contaminants by microorganisms when oxygen is present. More specifically, it refers to occurring or living only in the presence of oxygen; therefore, the chemistry of the system, environment, or organism is characterized by oxidative conditions.
What is Aerobic Biodegradation testing of plastics?
Aerobic Biodegradation testing of plastics is testing of plastics in aerobic conditions such as soil, compost, sea water.
Which is the test method for Aerobic Biodegradation testing of plastics?
ASTM D 5988/ ISO 17556 for soil
ASTM 5338/ ISO14855 for compost
ASTM 6691 for sea water
What is Anaerobic Biodegradation?
The degradation of compounds by microorganisms in the absence of oxygen is termed as Anaerobic Biodegradation. The process whereby microorganisms use a chemical other than oxygen as an electron acceptor.
What is Anaerobic Biodegradation testing of plastics?
Anaerobic Biodegradation testing of plastics is testing of plastics in anaerobic high solid digestion conditions that resembles landfill conditions.
Which is the test method for Anaerobic Biodegradation testing of plastics?
ASTM D 5511 Or ISO 15985
How to test compostable plastics?
You can test compostable plastics by testing the products as per ASTM D 6400 or ISO 17088 specifications
