Foreword
The standard paper and cardboard to take samples partially modified using ISO 186.2002 "Paper and board Determination of the average mass of the sample taken."
This standard and ISO 186.2002 Differences in Appendix B.
This standard is GB/T "to take a sample of paper and cardboard," 450-2002, measurement GB/T 452.1-2002 "aspect to the paper and cardboard
Fixed "and GB/T 452.2-2002" Paper and cardboard measuring positive and negative "integration amendment.
This standard replaces GB/T 450-2002, GB/T 452.1-2002 and GB/T 452.2-2002.
This standard and GB/T 450-2002, GB/T 452.1-2002 and GB/T 452.2-2002 compared to the main changes are as follows.
--- Increasing the sampling theorem;
--- Increasing the terms and definitions, as well as sampling method packaging unit packaging unit;
--- Specifies the sampling method consists of a single batch of product composition, increasing the extraction method of packaging unit sheet can not or should not be broken up;
--- Original standard paper tray sampling method into a roll or cardboard sampling method.
The Standard Appendix A, Appendix B are informative appendices.
The standard proposed by China National Light Industry Council.
This standard by the National Standardization Technical Committee of the paper industry.
This standard was drafted. China Pulp and Paper Research Institute.
The main drafters of this standard. High-SOCIALIST.
This standard replaces the standards previously issued as follows.
--- GB/T 450-1989, GB/T 450-2002;

--- GB/T 452.2-1989, GB/T 452.2-2002.
The standard National Standardization Technical Committee commissioned the paper industry is responsible for interpretation.
Paper and cardboard to take samples and
Vertical and horizontal sample, positive and negative determination
1 Scope
This standard specifies the aspect to take samples and specimens of paper and paperboard, positive and negative measurement.
This standard applies to all kinds of paper and cardboard.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
The same species, the same characteristics, and can be a sample of paper or paperboard assembly.
2.2
Composed of a number of components, which can be a form of a roll, one, bundle, a bag, a box, etc.
2.3
From the sheet (or product unit) according to a predetermined size cut out of paper or cardboard.
2.4
The aggregate of all samples taken from the batch is the average of the sample is used to reflect the average quality of the batch, and possibly as an evaluation of the bulk sample
basis.
2.5
Prescribed test method for testing a certain amount of paper or cardboard, usually a sample taken from the sample, the sample can sometimes be a sample of the
Body or several samples.
2.6
The sampling method should ensure that each part of the overall have the same chance of being selected.
2.7
With the machine running direction consistent with the longitudinal direction, and the direction perpendicular to the machine direction to landscape.
2.8
Sheet molding is not in contact with the paper machine forming wire surface is positive, also known as carpet surface; on the contrary, when the paper forming the paper machine forming wire phase
The contact surface is opposite, also known as mesh. This definition does not apply to double (folder) net production of paper or cardboard.
3 sampling theorem
Paper or paperboard from a number of randomly taken several packaging units, from the packaging unit randomly selected number of sheets, and then selected
