E) Supplementary References:
• Clarification of other indispensable standards.
• The complementary standard is indicated by its full number and title. If the draft has not yet been approved, its subject is indicated together with the phrase "which will be issued".
• Supplementary references may include standards issued by other available standardization bodies.
• If the date of the supplementary standard is not mentioned, the latest version should be applied.
• Supplementary references should not mention standards that are not available, criteria of information, or reference books used in the preparation of the standard.
F) Terms and definitions
• This optional item provides necessary definitions used to understand specific terms.
• If certain terms and definitions are mentioned in the standard, the item begins with "For purposes of this document, the following definitions and terms apply".
• If certain terms and definitions are mentioned in other standards, the item begins with "For purposes of this document, the terms and definitions mentioned in the following standard apply".
• Adherence to using definitions mentioned in the standard.
• A note that the term in this sense is used in the relevant field
• Commercial, old and odd terms should be avoided.
• The definition should include all necessary elements that help in understanding the meaning
• All expressions used in definitions should be clear
•Illustrations can be used to increase understanding
•International symbols and units should be used
• Basic requirements for standards of commodities and products
• All aspects of the product
• Value limits of these requirements are measurable
• Each requirement has a reference to the test method used
• Clear differentiation between characteristics, explanations, and recommendations
• Contract, legal and legislative requirements are not included
• In product standards, instructions for use and warnings may be necessary; however, they do not fall within the requirements as they do not apply to the product itself.
• This section specifies the conditions, methods of sampling, and methods of preservation.
• This item can be placed at the beginning of the test method item.
• When referring to sampling methods issued in a separate standard, this standard is indicated by the complete number and title of the standard.
I) Testing methods item:
• This item gives all measures taken to set values of properties or check conformity and ensure the accuracy of results.
• It arranges procedures related to testing methods in the following order:
4. Preparation and keeping of test sample;
5. Working method;
6. Presenting results along with method of calculation, limits of accuracy, and testing;
7. Test report.
• It is put in a separate, or part of, standard.
• Documentation of general testing methods as well as tests related to the same characteristics in other standards shall be taken into account.
• If they involve the use of hazardous substances, they should include a general warning.
• Only one testing method is mentioned in the standard.
• Testing methods are selected according to their accuracy.
J) Explanatory data and packaging:
Numbering, explanatory data and packaging are complementary topics to be included in consumer product standards, including:
1. Product identification data including factory name and address;
2. Marketing data using labels or cards;
3. Place of data;
4. Requirements for labeling or product packing.
K) Standard annexes:
Standard annexes give additional measures to the contents of the standard. They are optional.
• Tables are used when they are considered the most appropriate way to display information.
• The table number is indicated in the body of the standard.
• Tables are not divided into additional tables.
• If more than one, tables are numbered consecutively.
• The table number is followed by the table name.
• Measurement units are indicated in each column below the column header. If the units are identical in all columns, they are indicated above the table from the left side.
• Notes for each table are added within the table frame from the bottom.
M) Figures and graphs:
• Used when they are effective means of expression.
• Each figure takes a number starting with (1).
• If all units of measurement used in a figure are the same, the unit used on the left side is written above the graph
• Notes on each figure or graph is written below it.
N) Mathematical equations:
• Equations between quantities are placed in the form of mathematical equations between numeric values, while variables are placed in alphabetic characters. Then the meaning of these characters is defined taking into account not to repeat the same variable in one standard within the variable, which may cause incorrect results.
• Mathematical equations are numbered within one standard.
• They are put after the last annex.
• Sufficient information is mentioned to identify the source of reference books.
• Reference books are written in an alphabetical or numeric sequence.
• If the reference is electronic, it includes the address and electronic details in full.
