Current edition approved July 1, 2014. Published August 2014. Originally approved in 1954. Last previous edition approved in 2009 as D1349 – 09. — 2 p.
Reliable comparisons between different rubber compounds and between different laboratories is an essential component of effective testing.
It is necessary to standardize the temperature and humidity conditions to which materials are subjected prior to and during testing.
Section 2 of this practice includes the definition of terms commonly used to describe the conditions of testing.
Section 3 of this practice covers a list of standard test temperatures for testing from which selection may be made for a specification, procedure, practice, standard or method.
Any specification, procedure, practice, standard or method that specifies test temperatures shall take precedence over this practice.
The standard test temperatures for testing do not apply to preparation, mixing, processing, or vulcanizing temperatures for rubber compounds.
Section 4 of this practice covers a list of standard relative humidity conditions for testing from which selection may be made for a specification, procedure, practice, standard or method.
Any specification, procedure, practice, standard or method that specifies relative humidity shall take precedence over this practice.
The standard relative humidity conditions for testing do not apply to preparation, mixing, processing, or vulcanizing of rubber compounds, but may serve as a guide when the condition is not specified.
Section 5 of this practice covers the standard conditioning of materials for testing.
Any specification, procedure, practice, standard or method that specifies the conditioning of materials for testing shall take precedence over this practice.
Section 6 of this practice includes the keywords associated with this document which may be used in standard document or internet searches.
