Gives requirements for properties of polyimide woven glass fabric copper-clad laminated sheet of defined flammability, in thicknesses of 0,5 mm up to 6,4 mm.

Gives requirements for properties of bismaleimide/triazine modified epoxide woven glass fabric copper-clad laminated sheet of defined flammability, in thicknesses of 0,5 mm up to 6,4 mm.

Gives requirements for properties of thin bismaleimide/triazine modified epoxide woven glass fabric copper-clad laminated sheet of defined flammability for use in the fabrication of multilayer printed boards. Laminated sheets covered by this specification have thicknesses (copper foil not included) not greater than 0,8 mm (0.031 in).

Applies to composite insulators for use as suspension/tension line insulators. Deals with those composite insulators which include a 'core' and a 'housing'. Defines the terms used, prescribes test methods, prescribes acceptance criteria.

Concerns requirements and tests, in addition to those given in chapter 1 of IEC 60185, that are necessary when inductive current transformers are used with electrical protective schemes in which the prime requirement is the maintenance of a defined performance up to several times the rated current when the current contains an exponentially decaying d.c. component of defined time constant.

Defines how the thermal requirements of building users can be identified, expressed and quantified. Describes users' objectives and the parameters used to express them. Specifies units of measurement and means of evaluation.

Defines how the air purity requirements of building users can be identified, expressed and quantified. Describes users' objectives and the parameters used to express them. Specifies units of measurement and means of evaluation.

Defines how the acoustical requirements of building users can be identified, expressed and quantified. Describes users' objectives and the parameters used to express them. Specifies units of measurement and means of evaluation.

Specifies a test method for determining under defined conditions the resistance of a single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a hemispherically tipped needle.

Is a supplementary document to the sectional specification. Defines mounting, dimension, ratings and characteristics for fixed thick film resistor networks with individually measurable resistors, all of equal value and equal dissipation, class 1 (dual-in-line network), as well as inspection requirements.
