International Proficiency Schemes

 AACC International Proficiency Awards



Certificates of Proficiency

By participating in international proficiency schemes SAGL demonstrates our commitment to analytical accuracy and precision.


SAGL receives eight types of proficiency samples from AACC – International (American Association of Cereal Chemists) and two types of proficiency samples from Bipea – France (Bureau InterProfessionnel d'Etude Analytique).  In total the ten proficiency schemes cover nine chemical methods, four rheological methods as well as nine micronutrients and four mycotoxins over a range of at least five different products. 


1.         The bi-monthly AACC proficiency scheme samples consists of the following:  

        Chemical analyses

a.      Ash, protein, moisture, diastatic activity and falling number (hard wheat flour sample)

b.      Crude fibre, crude fat (EE), moisture, protein and ash (Animal feed sample)

c.      Dietary fibre and moisture

d.      Vitamins and minerals

         Physical analyses

a.    Farinogram (including moisture) (Hard wheat flour sample)

b.    Mixogram (including moisture and protein) (Wheat flour sample)

c.    Alveogram (including moisture) (Hard and soft wheat flour samples)

Mycotoxin analyses

a.    Total Aflatoxin, Fumonisin, Deoxynivalenol (DON), Zearalenone

2.         The Bipea proficiency scheme samples, received monthly from September through to June, consist of the following:

a.    Alveogram (Wheat flour sample)

Moisture, protein, falling number, ash, damaged starch, gluten (wet & dry), gluten index and alveogram

b.    Farinogram (Wheat flour sample)

Moisture and farinogram

Why the extra work and expenses?

Due to the methods that are SANAS accredited, SAGL’s internal Quality System (Policies and Procedures) and our participation in international proficiency schemes (AACC and Bipea), SAGL can firstly, confidently act as the grain-analysis reference laboratory in Southern Africa and secondly, with the same confidence, present national ring tests.
