KIA MS211-90 Glass Fiber (GF) or Mineral Powder (MD) Reinforced Polyamide 66 (PA66) - Recycled Polyamide 6 (PA6) Quality

The standard “KIA MS211-90 Glass fiber (GF) or mineral powder (MD) reinforced polyamide 66 (PA66) - Recycled polyamide 6 (PA6) quality” developed by Hyundai-Kia Motors Corporation, the oldest motor vehicle manufacturing company in Korea, describes a procedure for identifying the quality of glass fiber (GF) or mineral powder (MD) reinforced polyamide 66 (PA66) compound (recycled polyamide 6, PA6).

In the table titled “Authorized recycling” given in the standard, the type, recycling content and weight percentage are given as follows:

• Type A1: End-of-life vehicle recycling (50 percent plus/minus 5 percent) (such as radiator end tank, radiator fan, radiator casing)
• Type A2: End-of-life vehicle recycling (50 percent plus/minus 5 percent) (such as radiator end tank, radiator fan, radiator casing)
• Type D: Post-consumer recycling (35 percent plus/minus 5 percent)

Recycling refers to raw materials for recycling, which are wastes that are recovered/separated for recycling purposes.

End-of-life vehicle recycling, in this standard, means materials recycled using plastic parts from end-of-life vehicles.

Post-consumer recycling refers to recycled materials produced by end users (consumers, individuals, companies, organizations) of products that have fulfilled their intended purpose or are no longer usable.

Post-industrial recycling) refers to recycled materials that are diverted (not delivered to the consumer) during a production process (excluding reused materials such as reprocessing, regrind or scrap that are produced within a specific process and can be recovered within the same process).

The general requirements in this standard are described as follows:

• Parts utilizing this material must comply with all requirements of the applicable assembly performance specification.
• The chemical composition and processing conditions should not be changed inappropriately, which may affect the quality of the parts.
• Before changing the chemical composition of the material, it is mandatory to consult with the materials and quality control departments.
• Final parts made from this material must be free from defects, uneven shine, burn marks, warpage, silver streak, cracks, uneven color, flow marks, weld lines, sink marks or other defects.

Detailed requirements in this standard are included in a table provided within the standard.

This material is tested by the methods defined in the standard and must comply with the conditions specified in the table.

In general, the standard condition of the laboratory in the tests is 23 degrees plus/minus 2 degrees temperature and 50 percent plus/minus 5 percent relative humidity. The samples are carried out on the samples immediately after a conditioning period of at least 48 hours in the standard condition specified above at least 24 hours after molding.
