comparable (no detailed subgroups):

Technical Testing and analysis: This class includes the performance of physical, chemical
and other analytical testing of all types of materials and products such as:
Acoustics and vibration testing
Testing of composition and purity of minerals etc.
Testing activities in the field of food hygiene, including veterinary testing and control in relation to food production
Testing of physical characteristics and performance of materials, such as strength, durability, radioactivity etc.
Qualification and reliability testing
Performance testing of complete machinery: motors, automobiles, electronic equipment etc.
Radiographic testing of welds and joints
Failure analysis
Testing and measuring of environmental indicators: air and water pollution
– Certification of products, including consumer goods, motor vehicle, aircraft, pressurised containers, nuclear
plants etc.
– Periodic road-safety testing of motor vehicles
– Testing with use of models or mock-ups (e.g. of aircraft, ships, dams etc.)
– Operation of police laboratories
•
This class excludes testing of animal specimens and diagnostic imaging, testing and
analysis of medical and dental specimens.

Industry classification
•
NAICS 2007 - 541380 Testing Laboratories
•
Very similar to ISIC/NACE in that no separate
subgroups but description is more complete:
–
•
ANZSIC(2006) 6925 - Scientific testing and
analysis
–
•
Similar includes to ISIC/NACE but much more detail – 33 separate
‘includes’
It is comparable to NACE and ISIC but excludes units mainly engaged in
providing motor vehicle roadworthy inspections
Decomposition of current classification systems to
represent national activities of technical testing
–
e.g. The Netherlands, Norway

Product dimension
•
CPA 2008 (71.20) and CPC ver.2 (83.44) directly
comparable
•
Both identify five product groups:

Turnover Statistics
•
Definition: The sum of remuneration for rendering of
services to customers and sales of merchandise, and
gross income from other activities.
•
European countries obliged to measure both
turnover and prices
– SBS: Structural Business Statistics (annual
turnover amongst other variables)
– STS: Short Term Statistics (turnover and prices)
show short term economic trends

Turnover Statistics – progress and issues
• Of the 23 countries that reported progress to the VG
in 2011, 22 of them collected turnover data for the
technical testing industry at the industry level
• More specifically:
–
–
–
Norway: A mix-model approach using SBS, STS and administrative
data.
Germany: SBS are produced annually and STS quarterly.
Administrative data are provided by the German states tax
authorities (Länder)
Poland: collects data through three surveys, namely the Annual
survey on enterprises (SP), the Survey of small enterprises (SP-3)
and the Business Services survey

SPPI Development
• Pricing unit of measure – mixed depending on the
service being offered. Can be price per unit of time
for more complex testing or per test/analysis etc
• Distinction between administratively regulated and
freely negotiated prices.
E.g. in Germany prices for periodic safety tests for motor vehicles and
periodic mission tests for motor vehicles are decided by federal
regulation

Time-based methods
List prices
Advantages:

Particularly applicable when prices depend on
charge out rates of machinery and personnel (e.g.
List price charge out
certification)
rates, realized charge
Quality changes can be easily identified
out rates or computed 
Disadvantages:
charge out rates

Difficult to apply for heterogeneous services

Changes in productivity are not captured
Advantages:
List prices without additional 
Relatively simple pricing method for NSIs and
information on discounts and
respondents
surcharges
Disadvantages:

No real transaction prices

SPPI Development – quality issues
• Main quality adjustment methods used: overlap and
expert judgment
• Prices for exports should be monitored to ensure
exchange rate movements are controlled
• Where companies are subsidiaries of multinational
companies, prices might be set by the parent
company
