What is Sealed Sample for Test?

A sample shall be treated to be "sealed" if it is received in the laboratory in the following condition:

 All sealed samples should be properly wrapped, gala-sealed and signed by the person having signature in the forwarding letter.

Sample shall be packed/wrapped with cloth or paper in a manner so that contents of the pack cannot be removed/altered without tearing the seal and signature.

Having sample bags printed in manner as shown in figure above(Sampling Bituminous Mixes)can be very useful for recording information until such time as you can write a sample certificate

Samples not meeting these requirements shall be considered to be "Unsealed".
