Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
Specifies a volumetric method, after distillation, for determining of neutral oils, and a titrimetric method, after distillation, for determining of pyridine bases. The principle is based on distillation from an aqueous alkaline solution of a test portion. Measurement of the volume of neutral oils collected. Titration of the bases present in the aqueous distillate and in the oils with standard…

Simple empirical test of no great precision. The principle consists in shaking a test portion with sodium hydroxide solution under specified conditions and assessment of any insoluble matter present in suspension in the mixture by comparison either with an agreed standard turbidimetric solution or with sodium hydroxide solution. The comparison of the turbidity of the two solutions is carried out…

Simple empirical test of no great precision. The principle consists in shaking a test portion with sodium hydroxide solution under specified conditions and assessment of any insoluble matter present in suspension in the mixture by comparison either with an agreed standard turbidimetric solution or with water. The comparison of the turbidity of the two solutions is carried out by viewing…

Specifies a method for the comparison of the colour of a test portion against the colour of colorimetric standard colour matching solutions. The colour of cresols present in the test portion is liable to darken on keeping and on exposure to ligth. ISO 1897/7 replaces ISO Recommendation R 1909-1971.
Embossed Credit Cards - Specifications, Numbering System and Registration
Procedure
This standard for embossed credit cards defines the physical
specifications of the card, type fonts, location and dimensions
of the embossed data and an account numbering system. It further
specifies the procedure by which card issuer identifiers shall be
registered and promulgated for the information and use of all
concerned.
1. SCOPE
1.1 This Standard covers the requirements for the safe installation,
operation and maintenance of woodworking machinery, including cooperage
and veneering operations and the finishing of wood products.
1.2 This Standard does not apply to logging and primary milling operations.
Continuous mechanical handling equipment — Safety code for conveyors and elevators with chain-elemen...
The aim is to give examples for the guarding of nip points between the chains and the sprocket wheels or caterpillar drives for all conveyors and elevators using chains as transporting elements. Describes different safety devices. Supplements the various International Standards dealing with safety of continuous mechanical handling equipment.
