ASTM Standards

When refering to ASTM standards what is the difference between;

Standard Specification
Standard Practice
Standard Guide

None of them are codes (legally binding) so I am curious as to what the difference is.

Re: ASTM Standards

: When refering to ASTM standards what is the difference between;

: Standard, as used in ASTM International, a document that has been developed and
established within the consensus principles of the Society and that meets the approval requirements
of ASTM procedures and regulations.

DISCUSSION—The term “standard” serves in ASTM International as a nominative adjective in the title of documents, such as test methods or specifications, to connote specified consensus and approval. The various types of standard documents are based on the needs and usages as prescribed by the technical committees of the Society.

: Standard Practice, a definitive set of instructions for performing one or more specific operations that does not produce a test result.

DISCUSSION—Examples of practices include, but are not limited to: application, assessment, cleaning, collection, decontamination, inspection, installation, preparation, sampling, screening, and training.

: Standard Guide, a compendium of information or series of options that does not recommend a specific course of action.
DISCUSSION—A guide increases the awareness of information and approaches in a given subject area.

Specifcation, specification, n—an explicit set of requirements to be satisfied by a material, product, system, or service.

DISCUSSION—Examples of specifications include, but are not limited to, requirements for; physical, mechanical, or chemical properties, and safety, quality, or performance criteria. A specification identifies the test methods for determining whether each of the requirements is satisfied.


: None of them are codes (legally binding) so I am curious as to what the difference is.

A word of caution while these are not codes (legally binding) they are incorpoarted by refernce into code, hence they do become legally binding. A good example is the OSHA (Health and Safety Standards ) 29CFR1910 & 29CFR1926.
