This standard outlines a code of safety for chemical laboratories.
1 Scope
1.1 This standard outlines a code of safety for chemical laboratories.
1.2 The standard outlines:
(a) general rules of conduct concerning safety;
(b) details for fire emergency and rescue procedures;
(c) general laboratory techniques.
1.3 This standard does not cover hazards relating to radioactive substances.
Prescribes the requirements for metric capacity measures of cylindrical and conical shapes. It is intended for use by manufacturers in manufacturing Metric Capacity Measures thus ensuring all measures of a specified type and capacity will have the same dimensions. These measures are intended for use in normal commercial transactions and are for use in measuring liquids only. 7p. (Price Code B)
1.1 This standard specifies:
(a) requirements for the manufacturing, alloying and testing of gold articles of 23, 22, 20, 18, 15, 14, 12, 10 and 9 kt gold;
(b) requirements for findings and solders to be used in the manufacture of gold articles;
(c) methods for assaying gold, alloyed gold, solder, findings and gold articles;
(d) non-destructive testing of gold articles by X-ray fluorescence spectroscopy (XRF); and
(e) requirements for making and labelling of imported gold articles.
NOTE 1 It does not specify requirements for design of gold articles and does not apply to gold articles intended for industrial purpose such as dentistry, electronics, official coins, gold bars and other such uses.
This standard specifies:
a a) requirements for the manufacturing, alloying and testing of gold articles of 23, 22, 20, 18, 15, 14,12, 10 and 9 kt gold;
b b) requirements for findings and solders to be used in the manufacture of gold articles;
c c) methods for assaying gold, alloyed gold, solder, findings and gold articles; and
d d) requirements for marking and labelling of imported gold articles.
NNOTE It does not specify requirements for design of gold articles and does not apply to gold articles intended for industrial purposes such as dentistry, electronics, official coins, gold bars and other such uses.
This standard specifies inter alia conversion factors to be used in converting quantities measured in Imperial to SI and other units. It sets out procedures for the uniform use for these conversion factors. It is intended for use in everyday operations in government commerce, industry, education certain branches of technology and sport.
This International Standard gives specifications for the angular coordinate system to be used in the design of scales, reticles or other display means incorporated in instruments for determining optical data on human eyes or corrective lenses for human eyes.
This standard specifies requirements for the operation of laboratories and is applicable to all laboratories regardless of the number of personnel or the extent of the scope of testing activities.
This standard is for use by laboratories in developing their quality, administrative and technical systems that govern their operations. Any party may use this standard when confirming or recognising the competence of laboratories.
This standard specifies requirements for the operation of testing and/or calibration laboratories. It is applicable to all laboratories regardless of the number of personnel or the extent of the scope of testing activities.
