The purpose of the study is to adapt the requirements of the international standard ISO/IEC 17025: 2017 “General requirements for the competence of testing and calibration laboratories”, defining the functions and responsibilities of laboratory personnel, to the domestic forensic expert activity. The following requirements for personnel are addressed in the article: impartiality, competence, manageability, and performance of operations according to the laboratory’s management system. International standards and comments to them, foreign forensic practice, publications on domestic forensic expert science, and procedural codes of the Russian Federation have been analyzed. The article points out that in forensic organizations, the entire staff divides into two groups: those who perform forensic examinations (research) and those who ensure the functioning of the forensic organizations. Achieving objectivity in laboratory activities during research or testing is strictly applicable and is regulated by documenting the research/ test, validating research/test methods, training and admitting personnel, and maintaining equipment. The combination of these procedures ensures the objectivity of a study. It is shown that the standard extends its provisions to all accredited organizations under the uniform rules, which goes along with the ethical standards of the forensic expert institutions of the Ministry of Justice of the Russian Federation, other departments, as well as commercial organizations.

SummarySeveral methods of estimating the heparin neutralizing capacity of protamine were investigated for their reliability and practicability. The results from two chemical methods were compared with those from two in vitro biological assays, one of which was the method of the British Pharmacopoeia (1973). An in vivo method using mice was used to assess the accuracy of the in vitro test methods. Three standard heparin preparations were tested against the W.H.O. 1st International Reference Preparation for Protamine. Two of the heparin preparations were of mucosal origin, one of which was the 3rd International Standard, and the third heparin preparation was of lung origin (the 2nd International Standard for Heparin).The mean neutralization values (all methods) of heparin by protamine for a House Reference Preparation and the 3rd and 2nd International Standards for Heparin were 95.8, 109.8 and 89.9 units per mg of Protamine, respectively. All the methods read the House Reference Preparation to have a lower value than the 3rd International Standard, which had a higher value than the 2nd International Standard for Heparin. There was a constant relationship between the results of any one method and those of another. The chemical and in vitro biological methods gave results of comparable precision although the latter required a greater degree of technical skill and time to perform.

The Impact

Purpose Library impact and how to evaluate it has been debated for a number of years. While the activity – the busy-ness – of the library is now routinely measured and described, the difference the library makes is less tangible and harder to measure. Libraries in all sectors and worldwide are grappling with this issue, and the purpose of this paper is to summarise international standards available to support them. Design/methodology/approach The first international standard concerning library impact, ISO 16439 Information and documentation – methods and procedures for assessing the impact of libraries, was published in 2014 after several years in development. Findings The standard describes a range of methods for assessing library impact which have been used across the world in a variety of libraries in all sectors. Originality/value This paper summarises the key methods described in the standard, and gives references for further reading.

The fan industry has developed rapidly because of the large demand in the fields of thermal power, metallurgy and so on. There are many manufacturers in Zhejiang Province. However, energy efficiency projects are not carried out sufficiently in those factories. Compared with foreign standards on fan energy efficiency such as ANSI/AMCA 205 and ISO 12759, national standard GB 19761 still has some disparity in the scope of application, the energy efficiency classification and definition of energy efficiency. Using the experience of foreign standards and vigorously promoting the energy efficiency projects in the fan manufacturing enterprises could accelerate the development of domestic standard system on fan energy efficiency and entire fan industry.

This chapter outlines the theoretical and empirical puzzles that inform the book, its objectives, overall argument, and structure. This research sets out to explain the post-crisis international regulation of derivatives markets. In particular, it addresses three interconnected questions. What factors drove international standard-setting concerning derivatives post-crisis? Why did international regime complexity emerge? How was it managed and with what outcomes? The focus of this volume is on international standards, not the domestic implementation of these standards, or other domestic regulatory reforms concerning derivatives. This chapter also outlines the book’s theoretical and empirical contributions to the international relations literature on regime complexity and the international political economy literature on the regulation of finance.

Further Development

The fitness-for-service assessment is widely used to demonstrate whether identified defects or in-service deterioration threaten the structure integrity of the pressure equipment. This article introduces the development of the Chinese national safety assessment standard. The assessment procedure and assessment techniques of current Chinese national safety assessment standard GB/T 19624-2004 are demonstrated, and the improvement is proposed. In order to maintain availability of aging equipment and enhance the long-term economic performance of in service pressure equipment, a new Chinese national safety assessment standard system is methodology proposed based on the analysis of some international structure integrity procedures or standards. A new national standard fitness-for-service which focuses on the evaluation of in-service damage and degeneration will be established while GB/T 19624 is applicable for general defects.

Abstract Background: Prostate-specific antigen (PSA) measurements in serum by immunoassay are widely used in the screening, diagnosis, and monitoring of patients with prostate cancer although the lack of common reference reagents has led in the past to wide differences in estimates. We report here the results of a WHO international collaborative study in which two preparations of PSA representative of the main immunoreactive components in serum, free PSA and PSA 90:10, and a preparation of recombinant DNA-derived PSA were assessed as potential standards for the calibration of diagnostic immunoassays for PSA. Methods: Coded vials of the candidate materials and serum preparations containing PSA in the clinically important range were provided to the 10 laboratories in the study, and participants were asked to perform PSA assays currently in use in their laboratories. Data from 89 immunoassays by 26 different method-laboratory combinations were contributed to the study and analyzed centrally at the National Institute for Biological Standards and Control. Results: Potency estimates of the preparations relative to the in-house calibrators were in good agreement with the target value of 1 μg of total PSA/vial, the preparation of free PSA giving 1.10 μg/vial (95% confidence interval, 0.99–1.21 μg/vial) and PSA 90:10, 1.11 μg/vial (95% confidence interval, 1.04–1.18 μg/vial). No immunoreactivity was detected in ampoules containing the recombinant material. Use of a common standard of PSA 90:10 significantly reduced the between-laboratory geometric coefficients of variation for serum samples included in the study and gave a much narrower range of potency estimates. Conclusions: The preparation of free PSA was established by WHO as the First International Standard for PSA (free) with an assigned content of 1 μg of total PSA per vial. In addition, the preparation of bound PSA was established as the First International Standard for PSA (90:10) with an assigned content of 1 μg of total PSA per vial.

There is no national standard and international standard about nominal module operating temperature (NMOT) test methods for Building Integrated Photovoltaic (BIPV) modules. An in-lab testing method for measuring NMOT of BIPV modules is proposed. Based on the real operation condition of solar cell, the effect of ambient temperature, wind speed and optimal load resistor to operating temperature were analyzed. The surface temperature, interior temperature and back temperature of BIPV module were measured and the NMOT was determined.
