17D003R0: Steel door frame – specification -

This Malaysian Standard specifies requirements for the design, fabrication and performance

of pedestrian door frame with a minimum Base Metal Thickness (BMT) of 1.0 mm, where all

surfaces are steel and the edges are steel and mechanically fixed.

 

It covers both complete doorsets, and door frames and hinges that could be used for doorsets with non-metallic leaves.

20D024R1: Ceramic tiles – Grouts and adhesives – Part 1: Terms, definitions and specifications for

Adhesives (First revision)

(ISO 13007 - 1:2014, IDT)

This part of ISO 13007 applies to ceramic tile adhesives for internal and external tile installations on walls and floors.


This part of ISO 13007 gives the terminology, concerning the products, working methods, application properties, etc., for ceramic tile adhesives. This part of ISO 13007 specifies the values of performance requirements for all ceramic tile adhesives
[cementitious (C), dispersion (D) and reaction resin (R) adhesives].


This part of ISO 13007 does not contain criteria or recommendations for the design and installation of
ceramic tiles.

19D004R1: Methods of testing cement - Part 6: Determination of fineness

(First revision

This document describes three methods of determining the fineness of cement.

 

The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process.

 

The air-jet sieving method measures the retention on sieving and is suitable for particles which

substantially pass a 2,0 mm test sieve. It can be used to determine the particle size distribution of

agglomerates of very fine particles. This method can be used with test sieves in a range of aperture

sizes, e.g. 63 µm and 90 µm.

           

The air permeability method (Blaine) measures the specific surface area (surface area related to mass)

by comparison with a reference material sample. The determination of the specific surface area serves primarily to check the consistency of the grinding process of one and the same plant. This method only enables a limited assessment to be made of the properties of the cement in use.
