Rubber, vulcanized or thermoplastic — Determination of the effect of liquids
Scope: This document describes methods of evaluating the resistance of vulcanized and thermoplastic rubbers to the action of liquids by measurement of properties of the rubbers before and after immersion in test liquids. The liquids concerned include current service liquids, such as petroleum derivatives, organic solvents and chemical reagents, as well as reference test liquids.

Rubber — Determination of ash — Part 1: Combustion method
Scope: This document specifies three methods for the determination of ash from raw rubbers, compounded rubbers and vulcanizates. The methods are applicable to raw, compounded or vulcanized rubbers of the M, N, O, R and U families described in ISO 1629 [1], except that:
Method A is not used for the determination of ash from compounded or vulcanized rubbers containing chlorine, bromine or iodine;
Method B is used for compounded or vulcanized rubbers containing chlorine, bromine or iodine. It is not applicable to uncompounded rubbers;
Method C is intended to be used for the determination of ash from raw, compounded or vulcanized rubber not containing chlorine, bromine or iodine by wrapping the test portion in ashless filter paper;
lithium and fluorine compounds can react with silica crucibles to form volatile compounds, giving low ash results.
This document does not cover the interpretation of the ash results as to the inorganic chemical content of a compound or vulcanizate, which is the responsibility of the analyst, who must be aware of the behaviour of rubber additives at elevated temperatures.

Classification of thermoplastic wood adhesives for non-structural applications
Scope: This European Standard classifies thermoplastic resin based wood adhesives for non-structural applications into durability classes D1 to D4 based on the dry and wet strengths of bond-lines measured under specified conditions after various conditioning treatments.
For special applications, further tests that do not fall within the scope of this European standard can be applicable.
The adhesives specified in this European standard are suitable for the bonding of furniture and interior structures, panelling, doors, windows, stairs etc. made of wood or derived timber products.
This European Standard does not specify the temperature resistance of bond-lines

Adhesives - Wood adhesives for non-structural applications - Determination of tensile shear strength of lap joints
Scope: This European Standard specifies tests for adhesives for wood and derived timber products for the assessment of their resistance to hot and cold water. It can be used for the assessment of the strength of bonds with a thin bond-line. It does not apply to adhesives for structural use or to the manufacture of particleboards, fibreboards and plywood. It does not replace tests on finished products.
