Typical vertical joints between two prefabricated ordinary concrete external wall components — Prope...
For the determination of the watertightness of a joint a method has still not been elaborated. Because of the fundamental importance of this property, solutions are proposed, by way of examples, that experiences and laboratory studies have shown to be satisfactory under the usual conditions. Is applicable to all public or private buildings, used as dwellings, offices, educational or hospital…
The dimensions specified are close to average dimensions of current production in most manufactering countries. The types of beakers are specified: a low-form beaker with spout an a tall-form beaker with spout. The nominal capacities, the material and the construction are described. The basic dimensions are tabulated and the incriptions are defined.
Horizontal joints between load-bearing walls and concrete floors — Laboratory mechanical tests — Eff...
Specifies methods of test for the determination ot the mechanical properties of horizontal joints between load-bearing walls and concrete floors subjected to vertical loading and moments transmitted by the floors. The walls may be interior or exterior walls composed of masonry or of prefabricated units and supporting a floor on one or on both sides.
Grooved vertical joints with connecting bars and concrete infill between large reinforced concrete p...
Specifies a laboratory mechanical method of test for the determination of the relationship between tangential loading and relative displacement for certain types of vertical joints between large reinforced concrete panels subjected to tangential loading. Is applicable to vertical joints between large wall-panels satisfying certain conditions defined in the standard.

Green coffee — Determination of proportion of insect-damaged beans
The method consists in visual examination of the external surface of beans to identify those which have been damaged by insects. Determination of the observed proportion, as a percentage, of damaged beans and, if possible, identification of the species of insect responible to damage. From the proportion of damaged beans thus determined: estimation of the confidence limits of the true proportion…
Traveller irrigation machines — Part 1: Laboratory and field test methods
Specifies test methods for machines intended for spreading of liquids, such as water, waste water, water with chemical solutions, liquid manure and sewage sludge. Applies to stationary hose coiling machines, mobile hose laying machines and mobile hose dragging machines, each equipped with flexible hose or pipe and sprinkling devices.
The purpose of the measuring method is to determine the residual camber height and length as a function of the load ("flattening test"). Gives some essential informations related to the parameters "contact load" and "standard camber length". Applies to cross-country skis of size 130 cm and longer.
Glass — Resistance to attack by hydrochloric acid at 100 degrees C — Flame emission or flame atomic ...
The specified method applies to pieces of glass, preferable flat but if necessary curved, but from articles of laboratory glassware. Sample pieces are subjected to an aqueous hydrochloric acid solution, and the amount of alkali metal oxides extracted per unit area is determined as a measure of the acid resistance. Apparatus, reagents, and procedure are specified.
